What pieces of information must a robot have to move to another step in the program?

• A. COMMAND POSITION, MOTION TYPE, and PLAY SPEED
• B. COMMAND POSITION and SPEED only
• C. MOTION TYPE and PLAY SPEED only
• D. COMMAND POSITION only

Answer: (A)

To move to another step in the program, the robot needs three pieces of information: COMMAND POSITION, MOTION TYPE, and PLAY SPEED. The COMMAND POSITION specifies the destination coordinates or pose the end effector must reach. The MOTION TYPE defines how the move is performed, such as a straight-line path or a joint-interpolated path, which determines the trajectory and how the axes coordinate during the move. The PLAY SPEED sets how fast the move should be executed, shaping timing, acceleration, and smoothness. Together, these three define the complete instruction for the next step: where to go, how to move, and how quickly. If any one is missing, the move would be undefined—no destination, no defined path, or no timing. Hence all three pieces are required.
