Been thinking of running a competition to give away some free PCBs and now that I have your attention thanks to Slashdot, here goes:

Prizes 15 PCB pairs (main controller and IR shield).

  • Individuals – 5 prizes of 1 PCB pair
  • Maker/Hacker spaces or other like minded groups – 2 prizes, each of 5 pairs of PCBs

To enter: Write a submission on what you would do with the SwarmRobot PCBs. The winners will be those displaying the best spirit of open sharing and learning in what they intend to do with the PCBs and how they intend to do this.

Hints:

  • Look at this sites goals and those of the AFRON competition
  • Swarm – of robots and people creating…..
  • Individuals – can work with others via the internet
  • Groups – can work as a group or with other groups
  • XinCheJian is one such group of individuals!
  • XincCheJian wiki has a lot of SwarmRobot information and ideas
  • Be creative, but realistic – it would be great if you can follow through with your ideas and the PCBS!
  • Look at this sites goals and those of the AFRON competition

Entries will close – near the end of November. Full details with closing time and how to submit will be published shortly. If you can’t wait – then look to how dangerousprototypes run the 7400 competition – loose and flexible rules, with core goals of encouragement and having fun!

The video shows three SwarmRobots being controlled by one InfraRed signal – sorry for the poor video quality.

Looking at ways to have some sort of SwarmRobot display for MakerCarnival in Shanghai in early November, found this AtTiny 2313 code which can decode RC5 IR. It compiled, loaded and ran (verified looking at serial data output), but it did not detect IR from several different remote controls tried.

Using this Arduino code, (which uses some really nice multi-protocol IR receive and transmit libraries) it was discovered that all the remote controls used where NEC protocol, not RC5! Research indicates the NEC protocol is very common in Asia!

Rather than find NEC code for the AtTiny, or write code decode NEC, I used the above library to send RC5 and now a SwarmRobot can receive commands and as the shows, several SwarmRobots can be controlled at the same time! Kept using RC5 because it actually sends two sets of information an ID and a command, so this really fits controlling robot X to do command Y, or group z of robots to all do same command.

The code is on GitHub: SwarmRobot AtTiny2313 and the Arduino transmitter.

Success:- Using one InfraRed transmitter LED and four receiver LEDs for 360 degree object avoidance. The program logic is very simple at present.

Unfortunately the setup is not yet reliable – works one day but not the next and there are still some initialisation issues.

Biggest issue seems to be that there are huge variations in the functionality of IR receiver LEDs and we have not found matching data sheets for the two types we are using!

Xinchejian SwarmRobotsThe fantastic capability of the XinCheJian SwarmRobots has been recognised with 2nd placing in the AFRON $10 robot competition Traditional (Roaming) category. The announcement made at World Maker Faire today (via Wired) awarded first place to Harvard’s research group and third place by to MIT University. XinCheJian’s high placing against such prestigious competition highlights just how good XinCheJian’s SwarmRobots are!

The SwarmRobots are still under rapid development with work progressing on coding object detection and inter-robot communications using the already developed InfraRed shield. Work is also underway on wireless charging and a Atmel 32u4 version. It has been a lot of fun to be part of this team as can be seen in these videos!

SwarmRobot with new IR shield PCB

SwarmRobot with new IR shield PCB

Just put in a huge effort to enter the Xinchejian SwarmRobot into the AFRON competition.

Also used the assembly instructions created as part of the entry to help run a  workshop with other Xinchejian members making SwarmRobots. The workshop was pretty successful, although our preparation was lacking a bit with an untested PCB that just arrived and was assembled for the first time during the workshop and a different power switch that did match the board!

Definitely time for a more relaxed pace – exploring the Lophilo and a few other projects!
