Position Control

If you want to create an actuator that uses the position of a joint or a location in the coordinate system as the driving parameter, use the Position Control command. You must apply the actuator to an existing joint so the rigid bodies have a defined axis to move about. You can apply a Position Control to angular joints for uses such as a robotic arm rotating to a specific angle, or to linear joints for uses such as an elevator rising to a specific height.

You can set angular path options to control how the actuator reaches the destination. You can set the motion to follow the shortest path or set the direction. If you set the direction, you can track multiple turns.

Use with other commands

You can use the Position Control command in conjunction with the following commands:

• Transport Surface — Apply a position control actuator to a transport surface to create conveyor systems that stop at a specific distance.
• Signal — Select a signal to control the force or torque of an actuator.
• Inverse Kinematics — Select the Data from External check box to deactivate the Constraints group so that you can use inverse kinematics to control the motion of the controller.
• Dynamic Material — Apply a position control actuator to a dynamic material and to control the production of a continuous rigid body, such as a roll of sheet metal unwinding to a specific length.
