Back from Suzhou

without comments

Last monday we traveled back from Suzhou. Unfortunately the robots have been delayed by the customs inspection, so we haven’t been able to continue working on them. Visiting the RoboCup 2008 has been a great experience, and I think it was certainly worth it to have 18 people working very committed on the completion of the robots. Next year in Austria we’ll be back :)

Suzhou update

without comments

Days fly past here. We managed to get the second robot (twente-TUlip or just TUlip2) working right in time. Just minutes after we did its first complete test (standing still) the delft-TUlip (TUlip1) broke one of its optical encoders for hip angle measurement. So tomorrow we’ll have to use the TUlip2 robot for the goal-keeping contest! At the dutchrobotics website also a blog is being kept with a lot of pictures and movie clips.

First day @ Suzhou

without comments

Today started with a lot of work on our robots. To be honest, they were not completely working when they got here, and due to transport and other circumstances, besides the ’scheduled work’ there is a lot more to solve, repair, invent, design and build.

Besides the dealings with our own two robots, there is some time fortunately to walk around in the main Expo room. Over 300 contestants (all in all- I’m not sure I understood the Chinese guide correctly) divided over about 100 teams participating in various categories: humanoid soccer, fish soccer (polo?), rescue robots, home robots, etc.
In lot of the leagues, the technology is very similar over all contestants. Especially in the teen size humanoid league a lot of teams are participating with robots build with dynamixel servo’s. Most have directly build a robot with the robotis kit and use the camera as its main sensor. The camera is used for detecting whether the robot has fallen to the floor (dark/no image). Some use accelerometers for balancing and a few use a gyro for active balancing. When they use one, they use an RC gyro (normally used for model RC helicopters)

humanoid league, testing A clever solution comes from a German team which uses a Nokia telephone as brain. The bioloid servo system comes with a controller which has an optional bluetooth interface module. Unfortunately bluetooth is not allowed, so the team equipped the standard Bioloid controller with an RS232 coupling. Using the telephone’s camera and irda connection the telephone controls the robot. The telephone also comes with a 3d accelerometer which can be used for robot stabilization.

So, a lot of inspiring ideas, lots of people, and hopefully tomorrow a robot that can at least stand still :)

Arrived in China for RoboCup 2008

without comments

long bus trip to suzhouWith the team ‘Dutch Robotics‘ the three technical universities are going to participate in the RoboCup 2008. After a long flight we arrived in Shanghai today, and took an almost equally long coach-trip to Suzhou, where the contest is being held. We are hopping from air-conditioned bus to air-conditioned hotel room, which is just as well, because outside it is 35 degrees! First impression: China is big. China is Huge. There must be living So Many People in China. Wow.
