Q76. During a design review, an engineer must reason about differential drive rather than rely on a memorized label. Which statement is defensible?

A. a robot arm with two wrist joints B. a robot with only hydraulic legs C. a stationary CNC fixture D. A mobile robot drive using independently controlled left and right wheels

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: Differential drive turns by changing the relative wheel speeds and moves straight when the wheel speeds are equal under ideal conditions.
