Not really.. braking using the current generated by the motor (acting as a
generator) once the power is removed from it. H-Bridge has what is called
a break bit. The break bit simply shorts the two terminals on the motor
together, generating a magnetic field that "brake's" the motor. This uses
virtually current from the batteries. But I do see the advantage of having
a motor capable of coasting.... so the selectable build option sounds cool.

| (...) I may be wrong - 'my' RCX is actually my brother's, and is 3 hours drive away - but doesn't the remote control with the official firmware do float when buttons released, but brake if forward and reverse are pressed together? Max (22 years ago, 17-May-02, to lugnet.robotics.rcx.legos)
