The average firing frequencies of slow depressor coxa (Ds) and slow extensor tibia (SETi) motor neurons are directly proportional to the average angular velocity of their joints during stance, and the average Ds and SETi firing frequency appears to be modulated on a cycle-by-cycle basis to control running speed and orientation.

A hexapod robot called Whegs I is described, which uses one motor for propulsion and two small servos for steering to move over various terrains and climb over small obstacles in a manner similar to a cockroach.
