| (...) Yes, but I think the "power" portion of the cycle will draw more, because it's always trying to go from stop to full speed. Like driving a car with the brakes on. Start with the brake totally pressed, and the more you push on the gas, the less (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)

| (...) The brake function (as far as I know) should not use more battery power as the short circuit is in the driver chip itself. The drivers are MOSFETs, so setting the H bridge to brake does not actually apply any battery power to the motor (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)

| (...) I've been using a power/brake method (instead of power/float) for quite some time in BrickOS. That was one of the first big steps in getting my Legway to work. ( (URL) ) It allows you to program a robot to make smooth turns (slow, instead of (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)

| (...) I'm doing somthing similair at the moment. My robot runs along a track and needs to be controlled so it doesn't go too fast. I've successfully written some code which limits the top speed, you may be able to modify it or just incorparate ideas (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)
