Group Buy – Doodle bot and competition

May 17th, 2013 § 1 comment § permalink


There’s a group buy happening right now! and a competition going on!

Dagu electronics has announced a competition: use a doodlebot to make the most awesome drawing to compete for prizes, plenty of prizes to be won! read about it here:

Lutz a long time member of XinCheJian has contacted them since we’re in china and negotiated a great deal if we do a group buy, our target.. at least 20 pieces and our price.. 198rmb/each

if you want to get a doodle bot and not participate in the competition instead that’s fine! but if you want to get in on the competition, then it’s even more awesome!

here is more information about the competition:

Sign up to the XinCheJian google group (email,  Send an email to  titled “programming competition” with the words “i Pledge to buy X amount of Doodlebots if we succeed in our group buy” then get ready to send 198rmb to a group buy alipay account or drop into XinCheJian and hand over the cash to a staff member!  Lets put a deadline of May 22nd on this so we can hack the doodlebot sooner than later. Do not transfer or pay until Lutz gives us the word via email and verify it by checking website.

Once the pledge is made, you’re on the hook for the cash!

City project new video

February 10th, 2013 § 2 comments § permalink

Happy new year. Right to the beginning of the new year of the snake here the new video of our city project. This shows the first test with the 3D mapping and projection. The robots are not moving yet since the roads are not completely done.

Project City

February 2nd, 2013 § 3 comments § permalink

We’ve started a new project in Xinchejian, the Project City, code name “Metropolis“.

More about the project will be in the wiki soon as we just begun. Today we built the table where the city will be installed.

IMG_6316 IMG_6317 IMG_6321 IMG_6315 IMG_6329

The project will be a fusion of 3D projection and robot hardware combined with mechanics and interactive components.

This project is open for all members with interest. There will be a huge part in 3D mapping/projection and this content has to be created too. The robotics and mechanical part will include Arduino based hardware for the movements, communication between the central computer and the city and interface for interactive components.

If you think you could help with something then just let us know.


X-Bot in following mode

January 24th, 2013 § 2 comments § permalink

X-Bot is evolving and now already smart enough to follow another X-Bot. What is so special about that you may ask. Well, there is this small quite technical looking robot and there is a program running in X-Bot’s brain (also called Microcontroller or MCU). To follow another robot means that they need to communicate and this works with infrared signals going from the leader to the follower and back. Leo did the programming and the hardware and is willing to share that with you. Just check this website regulary and see when the next workshop is scheduled. Build your own X-Bot in Xinchejian

If you want to support the X-Bot, buy a couple of them or just help to develop it further then please go to and see more details there.

I’m a brave robot – Workshop @ XinCheJian – 1/20/2013

January 23rd, 2013 § 2 comments § permalink

Last Sunday we had a brilliant workshop at XinCheJian — the brave robot workshop hosted by Yair Reshef, an artist from Iseral. Yair started the brave robot workshops as the idea of compassion in design and robotics is something he has been dealing with and the workshop is the chance to get it on. The brave robots in this project are the ones without micro-controllers and/or sophisticated programming. The robotic design is purely analog and mechanic based. You can make your brave robot without much electronic knowledge but you need to be creative to make your robot unique and have fun!

During the 3 hour workshop, everyone who joined finished their first brave robot. Thanks to the hard work on soldering! Perhaps we could expect a brave robot racing at XinCheJian sometime, why not?





RoboRacing – Bragging rights

December 16th, 2012 § 3 comments § permalink


Bragging rights, well deserved, the winner of this years Autonomous racing championship is EdwardRF with his entry XHD, a 10 second car that flew around the track, sticking like glue to the ground, nimble and hightech in one.

5 competitors competed for best time in time trials on the track for 2012, but only one would win. first up on the track was “Icecream Breaker” which unfortunately didn’t make it off the starting track.


The second contestant was Charlie “wallbanger” famed for it’s uncanny desire to hit every wall in the past, for this year it had an upgrade, 2 Sharp IR range sensors a powerful microservo, a high current motor driver all on top of an arduino nano built right into the original platform, he was no longer a wallbanger but a high powered racing car which clocked in at 7seconds in testing on the same course but different surface. Charlie set the time to beat at 14.62 seconds

XHD time to roll around, with a tough 14.62 seconds to beat, it started out on the track for 1 flawless lap, unfortunately the second lap was not as great, but it did clock in at 10.25seconds. this was the highest tech vehicle to race, PID controllers, wickedly expensive racing platform, 3 Sharp IR range sensors, 1 nano, 1 703n, 1 micro servo, 1 high power motor for the quad wheel drive-shaft with differential driving allowing it to take corners like no ones business.

With a little intermission Cherokey was ready to try again, this 4 wheel drive platform from dfrobot needed a little more time to work out the bugs but it was a great start, it could turn 360° on the spot! equipped with 4 Basic IR sensors, 4 powered wheel drive shaft and a nice base, unfortunately it’s fastest time on the track was 25.02 seconds with 1 collision making it 35.02 seconds.


With man behind the wheel in the only entrant into the User controlled group Stanley clocked in with Loader Shovel with 31.96 seconds, not a good start for human controlled. anyway he won by default.

Lio finally entered in with the Lone Ranger – unfortunately time and a new platform didn’t work out for him, it was a good show of walloping wall-banging!.

in winner takes all, EdwardRF took home the prize of 500rmb :) congratulations to EdwardRF, if you would like to challenge him, make sure you have a 10 second car or you’ll be paying the price of loosing to the champion.

RoboRacing – Final Races for Bragging rights

December 2nd, 2012 § 0 comments § permalink

A few of us have gotten together to organize a Robo race on the 16th of December 2012 at 1pm, we’re racing autonomous, it’s purely for fun but also bragging rights for the end of the season.

If you would like to join us to race (you can be a spectator but its more fun to join in) then sign up for the event, to enter Autonomous racing you’ll need to drop 100rmb into the robo racing box, the ultimate winner will take the winnings, if there is no winner, then the money goes into XinCheJian’s donation box.  We’re doing it for fun with a little incentive.

If you would like to race a line follower please sign up, there is no prizes for that category and is free to enter (for now, but if you want an incentive then we can put an entry fee on this). Who knows, there might not be a robo racing season next year, so build and join in!

1: autonomous course – entry 100rmb winner takes all (Challenge track)

2: line follower – entry ???rmb winner takes all? << track

Robotics Spectacular at XinCheJian!

October 16th, 2012 § 0 comments § permalink

Bring out your robots! We will have an evening dedicated to Robotics talks next Wednesday evening at XinCheJian (1035 Changle Rd, 2nd floor, Xuhui District, Shanghai, CHINA, 200031) from 19h00 to 21h00. Talks will be between 8 and 20 minutes each. You have a robot but no presentation? Feel free to demo it before and after the talks!

Prof. Dr. Rolf Pfeifer from the AI Lab at the University of Zurich will be talking about his work in robotics (such as Roboy) in a talk entitled “Embodied Intelligence”. Dr Pfeifer is the worldwide leader on how well designed intelligent bodies can dramatically reduce non-linear control complexity (“embodiment”) and the Deputy Director of the NCCR (National Competence Center for Research in Robotics) in Switzerland.

Dr Ricky Ye (叶琛) and Rockets Xia (夏青) from DFRobot will bring and present a set of their commercial robots and how they’re approaching development of robots with OpenSource and OpenHardware.

Spencer Featherstone and Edward Jiang (姜昊) will give an update on XinCheJian Swarm Robots. Our swarm robots placed second at the AFRON competition, just between Harvard and MIT!

Rodolfo “Rudy” Cossovich will show off making robots with Multiplo, the robot building system. Rudy has just recently successfully completed a round of fundraising on Kickstarter for Multiplo.

Announcement by Ricky Ng-Adam (伍思力), translated to Chinese by Amaca Wang, revision by Min Lin Hsieh. Robot drawing by Kevin Chen.
