The Caterpillar (production prototype)
Caterpillar Evolution video shows how this project has gone from a simple hobby robot to a mass produced robot. The first clear ABS caterpillar is now up to mischief in China :D
Update 3 of July 2009
Well the first prototypes came out of the factory and of course some calibration is always required. DAGU contacted me to say they had a problem. It seems the program needs calibration to work with the new roll sensor as resistors can vary slightly even when they are all marked as the same value. Consequently the caterpillar constanly thinks it has fallen over and needs to get back up. The end result is quite funny :D
Whoops!, my mistake :0
I specified a different analog input in the schematic to what was being used in the program.It's all fixed now :D
I have posted some pictures if the new circuit boards used. The Antenna now use springs where I had wire, this is a big improvement as occasionally the wire got bent when stuck in a corner or getting back up on it's feet. Once the wire was bent it kept thinking it had hit something.
The IR sensor has been moved to the top of the roll sensor board so that it can recieve IR better.
