A spherical roller is just a ball in a loose fiting socket like on the underside of a mechanical mouse. (Computer pointing device, not a robo-rodent !) Some people actually use the tops of roll on anti-perspirant bottles for casters on small (...) (24 years ago, 9-Mar-01, to lugnet.robotics)

I have heard that RCX 2.0 has more memory in it than RCX 1.0 . Could you use tools like RcxCC to check the amount of memory in your RCX 2.0? Cheers, Hao-yang Wang (24 years ago, 8-Mar-01, to lugnet.robotics)

Hi folks, Apologies if this has been asked before, but I'm a little stumped. I just received a RIS 1.5 set, and inside was a yellow brick labelled RCX 2.0. I'm reasonably familiar with the RCX 1.0, and I have a 1.0 with a power jack. This one has no (...) (24 years ago, 8-Mar-01, to lugnet.robotics)

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)

I designed a caster wheel assembly that worked pretty well. It uses a single, centered wheel instead of the two wheels you have. The two wheel assembly you are using tends to not want to turn. Anyway go to the following web site for assembly (...) (24 years ago, 7-Mar-01, to lugnet.robotics)
