Using the Worm and Gear Constraint Block - Solar Tracker

This example illustrates the use of the Worm and Gear Constraint block to model a solar tracker. A slew drive containing a worm and gear constraint powers the yaw rotation of the solar trackers. The worm and gear geometry gives a large reduction in a single stage of gearing which provides precision tracking and high torque output. The yaw rotation is specified as a motion input to the gear revolute joint and the necessary actuator torque is automatically computed at the worm revolute joint.
