I'm just about done with my 3 robot project but have one last problem. I've
posted before and have taken people's advise on building this project but
alas I have one last barrier before I can present this at work for our Bring
a Child to Work Day presentation. Please visit my website for details of
the project and what my FINAL PROBLEM is.

Bascially, I can not get one of the robots to go in a staright line.
Thanks

| Here's three ideas ranging from easy to implement, but not terribly effective, to fairly effective, but harder to employ. You could try to characterize the amount of rotation that occurs in the robot as the caster wheel straightens out when you (...) (24 years ago, 7-Mar-01, to lugnet.robotics)

| Sorry about getting to this so late. This message got lost. (...) I suggest replacing the wheels on your caster with medium pulleys (the ones similar to 24t gears), WITHOUT putting the "O-ring" tires on them. I have found this to be an excellent (...) (24 years ago, 23-Mar-01, to lugnet.robotics)
