| | | How does a balancing robot like Legway balance on a patterned floor? Or can it? I've got some of the way there. My understanding from reading the web descriptions of various projects is that you _ought_ to measure - angle of tilt - rate of change (...) (21 years ago, 20-Jan-04, to lugnet.robotics)

I choose to ease the problem by lowering center of gravity (I put the bottom of (...) (21 years ago, 28-Jan-04, to lugnet.robotics)

| | | | | (...) I don't think there's a good source for this data (motor back-emf) using an RCX. Yes, Legway just used the motor commands to simulate the wheel velocity. It would have greatly increased the complexity of the wheel assembly to add rotation (...) (21 years ago, 22-Jan-04, to lugnet.robotics)

| | | | | | (...) Um, the back-EMF of the motore isn't related to the motor load per se but rather the relaxation of the current in the coil when it moves off the stators. It's also very fast (ie E=Bc) so the RCX isn't likely to get good readings for this. It's (...) (21 years ago, 22-Jan-04, to lugnet.robotics)
