for everyone

After handing in my master's thesis and a 3 day trip to Berlin, the rest of the easter was used to make a snake robot to participate in the DTU robocup. I made the robot together with Lars Pontoppidan whom I also wrote the thesis with.

The robot moves froward only based on the snake movement, lateral undulation, the wheels underneath are passive.

I'll write a bit about the robot later, but here are a couple of videos from the competition:

The first round:

The second round with a bit more interesting ending:

Other videos taken during the competition can be seen here.

Very Creative, Robotten fra Slangerup.
- do think it was trying to hide at the end?

Well it wasn't supposed to fall of the ramp, just stay at it until a timeout happened. Then across the course finding the black line at the other side... happened the night before!

wow very nice robot snake, what type of sensors did you use, did you put ucontroller for every snake body....very impressive work. i've created also my spider robot but some little errors occurs due to i ji=ust make use of an photo-xsistor as my sensor no much budget.....what type of ucontroller did you use, which do you prefer to use the PIC or the ZILOG ucontroller

Hi Mark
We used a single Atmel mega32 microcontroller. It generates a pwm signal for each of the 8 servos on the robot. To follow the line we used simple phototransistors.
You can find a good deal more on the robot on Lars' site: http://pontoppidan.info/lars/index.php?proj=sicksack
