True or False: Pushbuttons and keypads may be used for incremental control of robot motion.

• A. It depends
• B. Not commonly used
• C. True
• D. False

Answer: (C)

Incremental control relies on discrete inputs to advance motion in small steps. Pushbuttons and keypads fit this role because each press can be mapped to a fixed, predefined amount of movement for a robot joint or axis. This allows a human operator to nudge the robot precisely, step by step, which is exactly how jog modes and teach pendants are used in practice. If you want a tiny adjustment, press once; for another tiny adjustment, press again. Some systems may let a held input produce continuous motion or alter the step size, but the core idea remains that these devices enable controlled, incremental movement rather than a single seamless velocity. So the statement is true: pushbuttons and keypads can be used for incremental control of robot motion.
