  31         <p>After many months of hard work by the good people involved in
  32 <a href="https://en.wikipedia.org/wiki/LinuxCNC">LinuxCNC</a>, the
  33 system was accepted Sunday
  34 <a href="https://tracker.debian.org/pkg/linuxcnc">into Debian</a>.
  35 Once it was available from Debian, I was surprised to discover from
  36 <a href="https://qa.debian.org/popcon.php?package=linuxcnc">its
  37 popularity-contest numbers</a> that people have been reporting its use
  38 since 2012.  <a href="http://linuxcnc.org/">Its project site</a> might
  39 be a good place to check out, but sadly is not working when visiting
  40 via Tor.</p>
  41
  42 <p>But what is LinuxCNC, you are probably wondering?  Perhaps a
  43 Wikipedia quote is in place?</p>
  44
  45 <blockquote>
  46 "LinuxCNC is a software system for numerical control of
  47 machines such as milling machines, lathes, plasma cutters, routers,
  48 cutting machines, robots and hexapods. It can control up to 9 axes or
  49 joints of a CNC machine using G-code (RS-274NGC) as input. It has
  50 several GUIs suited to specific kinds of usage (touch screen,
  51 interactive development)."
  52 </blockquote>
  53
  54 <p>It can even control 3D printers.  And even though the Wikipedia
  55 page indicate that it can only work with hard real time kernel
  56 features, it can also work with the user space soft real time features
  57 provided by the Debian kernel.
  58 <a href="https://github.com/linuxcnc/linuxcnc">The source code</a> is
  59 available from Github.  The last few months I've been involved in the
  60 translation setup for the program and documentation.  Translators are
  61 most welcome to

 131       <div class="body">
 132         <p>A while back a college and friend from Debian and the Skolelinux /
 133 Debian Edu project approached me, asking if I knew someone that might
 134 be interested in helping out with a technology project he was running
 135 as a teacher at <a href="https://www.ecolefrancodanoise.dk/">L'école
 136 franco-danoise</a> - the Danish-French school and kindergarden.  The
 137 kids were building robots, rovers.  The story behind it is to build a
 138 rover for use
 139 <a href="http://blog.ecolefrancodanoise.dk/first-week-on-the-dark-side">on
 140 the dark side of the moon</a>, and remote control it.  As travel cost
 141 was a bit high for the final destination, and they wanted to test the
 142 concept first, he was looking for volunteers to host a rover for the
 143 kids to control in a foreign country.  I ended up volunteering as a
 144 host, and last week the rover arrived.  It took a while to arrive
 145 after <a href="http://blog.ecolefrancodanoise.dk/model-moms">it was
 146 built and shipped</a>, because of customs confusion.  Luckily we were
 147 able fix it quickly with help from my colleges at work.</p>
 148
 149 <p>This is what it looked like when the rover arrived.  Note the cute
 150 eyes looking up on me from the wrapping</p>

 155
 156 <p style="text-align:left">Once the robot arrived, we needed to track
 157 down batteries and figure out how to build custom firmware for it with
 158 the appropriate wifi settings.  I asked a friend if I could get two
 159 18650 batteries from his pile of Tesla batteries (he had them from the
 160 wrack of a crashed Tesla), so now the rover is running on Tesla
 161 batteries.</p>
 162
 163 <p>Building
 164 <a href="https://gitlab.com/ecolefrancodanoise/arduino-efd/">the rover
 165 firmware</a> proved a bit harder, as the code did not work out of the
 166 box with the Arduino IDE package in Debian Buster.  I suspect this is
 167 due to a unsolved
 168 <a href="https://github.com/arduino/Arduino/pull/2703"> license problem
 169 with arduino</a> blocking Debian from upgrading to the latest version.
 170 In the end we gave up debugging why the IDE failed to find the
 171 required libraries, and ended up using the Arduino Makefile from the
 172 <a href="https://tracker.debian.org/pkg/arduino-mk">arduino-mk Debian
 173 package</a> instead.  Unfortunately the camera library is missing from
 174 the Arduino environment in Debian, so we disabled the camera support
 175 for the first firmware build, to get something up and running.  With
 176 this reduced firmware, the robot could be controlled via the
 177 controller server, driving around and measuring distance using its
 178 internal acoustic sensor.</p>
 179
 180 <p>Next, With some help from my friend in Denmark, which checked in the
 181 camera library into the gitlab repository for me to use, we were able
 182 to build a new and more complete version of the firmware, and the
 183 robot is now up and running.  This is what the "commander" web page
 184 look like after taking a measurement and a snapshot:</p>

 214       <div class="body">
 215         <p>I am amazed and very pleased to discover that since a few days ago,
 216 everything you need to program the <a href="https://microbit.org/">BBC
 217 micro:bit</a> is available from the Debian archive.  All this is
 218 thanks to the hard work of Nick Morrott and the Debian python
 219 packaging team.  The micro:bit project recommend the mu-editor to
 220 program the microcomputer, as this editor will take care of all the
 221 machinery required to injekt/flash micropython alongside the program
 222 into the micro:bit, as long as the pieces are available.</p>
 223
 224 <p>There are three main pieces involved.  The first to enter Debian
 225 was
 226 <a href="https://tracker.debian.org/pkg/python-uflash">python-uflash</a>,
 227 which was accepted into the archive 2019-01-12.  The next one was
 228 <a href="https://tracker.debian.org/pkg/mu-editor">mu-editor</a>, which
 229 showed up 2019-01-13.  The final and hardest part to to into the
 230 archive was
 231 <a href="https://tracker.debian.org/pkg/firmware-microbit-micropython">firmware-microbit-micropython</a>,
 232 which needed to get its build system and dependencies into Debian
 233 before it was accepted 2019-01-20.  The last one is already in Debian
 234 Unstable and should enter Debian Testing / Buster in three days.  This
 235 all allow any user of the micro:bit to get going by simply running
 236 'apt install mu-editor' when using Testing or Unstable, and once
 237 Buster is released as stable, all the users of Debian stable will be
 238 catered for.</p>
 239
 240 <p>As a minor final touch, I added rules to
 241 <a href="https://tracker.debian.org/pkg/isenkram">the isenkram
 242 package</a> for recognizing micro:bit and recommend the mu-editor
 243 package.  This make sure any user of the isenkram desktop daemon will
 244 get a popup suggesting to install mu-editor then the USB cable from
 245 the micro:bit is inserted for the first time.</p>
 246
 247 <p>This should make it easier to have fun.</p>

 272         <p>A while back I received a Gyro sensor for the NXT
 273 <a href="mindstorms.lego.com">Mindstorms</a> controller as a birthday
 274 present.  It had been on my wishlist for a while, because I wanted to
 275 build a Segway like balancing lego robot.  I had already built
 276 <a href="http://www.nxtprograms.com/NXT2/segway/">a simple balancing
 277 robot</a> with the kids, using the light/color sensor included in the
 278 NXT kit as the balance sensor, but it was not working very well.  It
 279 could balance for a while, but was very sensitive to the light
 280 condition in the room and the reflective properties of the surface and
 281 would fall over after a short while.  I wanted something more robust,
 282 and had
 283 <a href="https://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&key=NGY1044">the
 284 gyro sensor from HiTechnic</a> I believed would solve it on my
 285 wishlist for some years before it suddenly showed up as a gift from my
 286 loved ones. :)</p>
 287
 288 <p>Unfortunately I have not had time to sit down and play with it
 289 since then.  But that changed some days ago, when I was searching for
 290 lego segway information and came across a recipe from HiTechnic for
 291 building
 292 <a href="http://www.hitechnic.com/blog/gyro-sensor/htway/">the
 293 HTWay</a>, a segway like balancing robot.  Build instructions and
 294 <a href="https://www.hitechnic.com/upload/786-HTWayC.nxc">source
 295 code</a> was included, so it was just a question of putting it all
 296 together.  And thanks to the great work of many Debian developers, the
 297 compiler needed to build the source for the NXT is already included in
 298 Debian, so I was read to go in less than an hour.  The resulting robot
 299 do not look very impressive in its simplicity:</p>
 300
 301 <p align="center"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-robot.jpeg"></p>
 302
 303 <p>Because I lack the infrared sensor used to control the robot in the
 304 design from HiTechnic, I had to comment out the last task
 305 (taskControl).  I simply placed /* and */ around it get the program
 306 working without that sensor present.  Now it balances just fine until
 307 the battery status run low:</p>

 311 </video></p>
 312
 313 <p>Now we would like to teach it how to follow a line and take remote
 314 control instructions using the included Bluetooth receiver in the NXT.</p>
 315
 316 <p>If you, like me, love LEGO and want to make sure we find the tools
 317 they need to work with LEGO in Debian and all our derivative
 318 distributions like Ubuntu, check out
 319 <a href="http://wiki.debian.org/LegoDesigners">the LEGO designers
 320 project page</a> and join the Debian LEGO team.  Personally I own a
 321 RCX and NXT controller (no EV3), and would like to make sure the
 322 Debian tools needed to program the systems I own work as they
 323 should.</p>

 344         <p>Drones, flying robots, are getting more and more popular.  The most
 345 know ones are the killer drones used by some government to murder
 346 people they do not like without giving them the chance of a fair
 347 trial, but the technology have many good uses too, from mapping and
 348 forest maintenance to photography and search and rescue.  I am sure it
 349 is just a question of time before "bad drones" are in the hands of
 350 private enterprises and not only state criminals but petty criminals
 351 too.  The drone technology is very useful and very dangerous.  To have
 352 some control over the use of drones, I agree with Daniel Suarez in his
 353 TED talk
 354 "<a href="https://archive.org/details/DanielSuarez_2013G">The kill
 355 decision shouldn't belong to a robot</a>", where he suggested this
 356 little gem to keep the good while limiting the bad use of drones:</p>
 357
 358 <blockquote>
 359
 360 <p>Each robot and drone should have a cryptographically signed
 361 I.D. burned in at the factory that can be used to track its movement
 362 through public spaces. We have license plates on cars, tail numbers on
 363 aircraft. This is no different. And every citizen should be able to
 364 download an app that shows the population of drones and autonomous
 365 vehicles moving through public spaces around them, both right now and
 366 historically. And civic leaders should deploy sensors and civic drones
 367 to detect rogue drones, and instead of sending killer drones of their
 368 own up to shoot them down, they should notify humans to their
 369 presence. And in certain very high-security areas, perhaps civic
 370 drones would snare them and drag them off to a bomb disposal facility.</p>
 371
 372 <p>But notice, this is more an immune system than a weapons system. It
 373 would allow us to avail ourselves of the use of autonomous vehicles
 374 and drones while still preserving our open, civil society.</p>
 375
 376 </blockquote>
 377
 378 <p>The key is that <em>every citizen</em> should be able to read the
 379 radio beacons sent from the drones in the area, to be able to check
 380 both the government and others use of drones.  For such control to be
 381 effective, everyone must be able to do it.  What should such beacon
 382 contain?  At least formal owner, purpose, contact information and GPS
 383 location.  Probably also the origin and target position of the current
 384 flight.  And perhaps some registration number to be able to look up
 385 the drone in a central database tracking their movement.  Robots
 386 should not have privacy.  It is people who need privacy.</p>

 407         <p>Back in 2010, I created a Perl library to talk to
 408 <a href="http://en.wikipedia.org/wiki/Spykee">the Spykee robot</a>
 409 (with two belts, wifi, USB and Linux) and made it available from my
 410 web page.  Today I concluded that it should move to a site that is
 411 easier to use to cooperate with others, and moved it to github.  If

 489         <p>As part of my investigation on how to improve the support in Debian
 490 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 491 Launcher and updated the Debian package
 492 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 493 sure udev will fix the device permissions when it is plugged in.  I
 494 also added a "Modaliases" header to test it in the Debian archive and
 495 hopefully make the package be proposed by jockey in Ubuntu when a user
 496 plug in his rocket launcher.  In the process I moved the source to a
 497 git repository under collab-maint, to make it easier for any DD to
 498 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 499 is not very active, but the software still work for me even after five
 500 years of relative silence.  The new git repository is not listed in
 501 the uploaded package yet, because I want to test the other changes a
 502 bit more before I upload the new version.  If you want to check out
 503 the new version with a .desktop file included, visit the
 504 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git">gitweb

 561         <p>This summer I got the chance to buy cheap Spykee robots, and since
 562 then I have worked on getting Linux software in place to control them.
 563 The firmware for the robot is available from the producer, and using
 564 that source it was trivial to figure out the protocol specification.
 565 I've started on a perl library to control it, and made some demo
 566 programs using this perl library to allow one to control the
 567 robots.</p>
 568
 569 <p>The library is quite functional already, and capable of controlling
 570 the driving, fetching video, uploading MP3s and play them.  There are
 571 a few less important features too.</p>
 572
 573 <p>Since a few weeks ago, I ran out of time to spend on this project,
 574 but I never got around to releasing the current source.  I decided
 575 today that it was time to do something about it, and uploaded the
 576 source to my Debian package store at people.skolelinux.org.</p>
 577
 578 <p>Because it was simpler for me, I made a Debian package and
 579 published the source and deb.  If you got a spykee robot, grab the
 580 source or binary package:</p>

 608       </div>
 609       <div class="body">
 610         <p>This evening I made my first Perl GUI application.  The last few
 611 days I have worked on a Perl module for controlling my recently
 612 aquired Spykee robots, and the module is now getting complete enought
 613 that it is possible to use it to control the robot driving at least.
 614 It was now time to figure out how to use it to create some GUI to
 615 allow me to drive the robot around.  I picked PerlQt as I have had
 616 positive experiences with the Qt API before, and spent a few minutes
 617 browsing the web for examples.  Using Qt Designer seemed like a short
 618 cut, so I ended up writing the perl GUI using Qt Designer and
 619 compiling it into a perl program using the puic program from
 620 libqt-perl.  Nothing fancy yet, but it got buttons to connect and
 621 drive around.</p>
 622
 623 <p>The perl module I have written provide a object oriented API for
 624 controlling the robot.  Here is an small example on how to use it:</p>
 625
 626 <p><pre>
 627 use Spykee;
 628 Spykee::discover(sub {$robot{$_[0]} = $_[1]});
 629 my $host = (keys %robot)[0];
 630 my $spykee = Spykee->new();
 631 $spykee->contact($host, "admin", "admin");
 632 $spykee->left();
 633 sleep 2;
 634 $spykee->right();
 635 sleep 2;
 636 $spykee->forward();
 637 sleep 2;
 638 $spykee->back();
 639 sleep 2;
 640 $spykee->stop();
 641 </pre></p>
 642
 643 <p>Thanks to the release of the source of the robot firmware, I could
 644 peek into the implementation at the other end to figure out how to
 645 implement the protocol used by the robot.  I've implemented several of
 646 the commands the robot understand, but is still missing the camera
 647 support to make it possible to control the robot from remote.  First I
 648 want to implement support for uploading new firmware and configuring
 649 the wireless network, to make it possible to bootstrap a Spykee robot
 650 without the producers Windows and MacOSX software (I only have Linux,
 651 so I had to ask a friend to come over to get the robot testing
 652 going. :).</p>
 653
 654 <p>Will release the source to the public soon, but need to figure out
 655 where to make it available first.  I will add a link to
 656 <a href="http://wiki.nuug.no/grupper/robot/">the NUUG wiki</a> for
 657 those that want to check back later to find it.</p>

 678         <p>I dag fikk jeg endelig tittet litt på mine nyinnkjøpte roboter, og
 679 har brukt noen timer til å google etter interessante referanser og
 680 aktuell kildekode for bruk på Linux.  Det mest lovende så langt er
 681 <a href="http://ispykee.toyz.org/">ispykee</a>, som har en
 682 BSD-lisensiert linux-daemon som står som mellomledd mellom roboter på
 683 lokalnettet og en sentral tjeneste der en iPhone kan koble seg opp for
 684 å fjernstyre roboten.  Linux-daemonen implementerer deler av
 685 protokollen som roboten forstår.  Etter å ha knotet litt med å oppnå
 686 kontakt med roboten (den oppretter et eget ad-hoc wifi-nett, så jeg
 687 måtte gå av mitt vanlige nett for å få kontakt), og kommet frem til at
 688 den lytter på IP-port 9000 og 9001, gikk jeg i gang med å finne ut
 689 hvordan jeg kunne snakke med roboten vha. disse portene.  Robotbiten
 690 av protokollen er publisert av produsenten med GPL-lisens, slik at det
 691 er mulig å se hvordan protokollen fungerer.  Det finnes en java-klient
 692 for Android som så ganske snasen ut, men fant ingen kildekode for
 693 denne.  Derimot hadde iphone-løsningen kildekode, så jeg tok
 694 utgangspunkt i den.</p>
 695
 696 <p>Daemonen ville i utgangspunktet forsøke å kontakte den sentrale
 697 tjenesten som iphone-programmet kobler seg til.  Jeg skrev dette om
 698 til i stedet å sette opp en nettverkstjeneste på min lokale maskin,
 699 som jeg kan koble meg opp til med telnet og gi kommandoer til roboten
 700 (act, forward, right, left, etc).  Det involverte i praksis å bytte ut
 701 socket()/connect() med socket()/bind()/listen()/accept() for å gjøre
 702 klienten om til en tjener.</p>
 703
 704 <p>Mens jeg har forsøkt å få roboten til å bevege seg har min samboer
 705 skrudd sammen resten av roboten for å få montert kamera og plastpynten
 706 (armer, plastfiber for lys).  Nå er det hele montert, og roboten er
 707 klar til bruk.  Må få flyttet den over til mitt vanlige trådløsnett
 708 før det blir praktisk, men de bitene av protokollen er ikke
 709 implementert i ispykee-daemonen, så der må jeg enten få tak i en mac
 710 eller en windows-maskin, eller implementere det selv.</p>
 711
 712 <p>Vi var tre som kjøpte slike roboter, og vi har blitt enige om å
 713 samle notater og referanser på <a
 714 href="http://wiki.nuug.no/grupper/robot/">NUUGs wiki</a>.  Ta en titt
 715 der hvis du er nysgjerrig.</p>

 736         <p>Jeg kjøpte nettopp to

 738 leking.  Kjøpte to da det var så billige, og gir meg mulighet til å
 739 eksperimentere uten å være veldig redd for å ødelegge alt ved å bytte
 740 ut firmware og slikt.  Oppdaget at lekebutikken på Bryn senter hadde
 741 en liten stabel på lager som de ikke hadde klart å selge ut etter
 742 fjorårets juleinnkjøp, og var villig til å selge for en femtedel av
 743 vanlig pris.  Jeg, Ronny og Jarle har skaffet oss restbeholdningen, og
 744 det blir morsomt å se hva vi får ut av dette.</p>
 745
 746 <p>Roboten har belter styrt av to motorer, kamera, høytaler, mikrofon
 747 og wifi-tilkobling.  Det hele styrt av en GPL-lisensiert databoks som
 748 jeg mistenker kjører linux.  Firmware-kildekoden ble visst publisert i
 749 mai.  Eneste utfordringen er at kontroller-programvaren kun finnes til
 750 Windows, men det må en kunne jobbe seg rundt når vi har kildekoden til
 751 firmwaren. :)</p>
