Thanks @jker. I tested the voltage across the output terminals and it was ok. I got a new L298N and it seemed to work much better. Perhaps it just was...

@robotbuilder I just used an L298N because I had one lying around. I think it's probably a bit faulty. I will see if I can test with another one. I th...

@robotbuilder Also, do you think I might get a better result with a MOSFET type motor controller?

@robotbuilder Sorry, that wasn't very clear. By power supply I meant battery without the motor controller. I think I should probably try a high...

Thanks @robotbuilder. I'm just using one of those cheapo plastic motors that come with the robot chassis kit. When I test the motor with a power suppl...

@byron You're welcome. I know what you mean. I have a million and one projects, plus kids and work. I think the key is to be consistent, even if yo...

Video link is here. Right motor stalls at end and causes robot to spin around.

I've managed to write some code for the potential fields. Basically it just takes an weighted average of the path to the obstacle and the object avoid...

@robotbuilder @codecage @byron @bigbadjohn Chasing away rabbits would be a good application in Australia. We have loads of them here. Also chasing ...

@codecage @bigbadjohn I am working on something at the moment with the potential fields for a small robot car. I will put my code up on github when ...

@briang Hi Brian, There are two wheels at the front as well. I followed Bill pretty much to the letter in building my chassis. Except the motors I...

Thanks Brian. That is so cool. This is what I've got. I will be looking to integrate some of your ideas onto it.

@wolfsbane What about using old compact discs for the feet. I like the idea of making it out of all recycled materials.

Is that thick plexiglass?
