| (...) Actually, it's more like standing on the brakes, letting go and then gunning the gas, stepping off the gas and standing on the brakes :-) And yes, that WILL use more gas, and more batteries. Now, if the resolutiion of timing for the brake (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)

| (...) 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)
