They appear to grip tightly enough that they never slip within the torque range of the micromotor. Don't worry about (...) (25 years ago, 24-Jan-00, to lugnet.robotics)

For the other two, I found a quick and easy way to add some slip: insert one or (...) (25 years ago, 24-Jan-00, to lugnet.robotics)

| | | | Unfortunatelly I don't have a clutch gear. It's hard to find and I can't order kits with it outside US. :( Pulleys and clutch gears can solve the problem but they requires more space. I really don't know if the friction pulley was designed for that (...) (25 years ago, 24-Jan-00, to lugnet.robotics)

| | | | I found a way to "regulate" the friction in the friction pulley. The point is that the axle doesn't need to be inerted all the way inside the rubber ring. You can insert it just a little and use small bushings to keep things in place. I used this to (...) (25 years ago, 29-Jan-00, to lugnet.robotics)
