Both statements I and II are correct.
Reason — Statement I is correct because gears are used in a robotic system to transmit motion and power and also to amplify force.
Statement II is also correct because the gear ratio depends on the number of teeth on the driving and driven gears. By choosing a suitable gear ratio, a robot can increase either its torque (force) or its rotational speed.
