Description

A LinearMotor node can be used to power a SliderJoint and a Track.

Field Summary

• The name field specifies the name identifier of the motor device. This the name to which the wb_robot_get_device function refers. It defaults to "linear motor".

• The maxForce field specifies both the upper limit and the default value for the motor available force and is expressed in newton [N]. The available force is the force that is available to the motor to perform the requested motions. When used in velocity control, this maximum force is always applied (with the correct sign) until the target speed is reached, more details are available here. The wb_motor_set_available_force function can be used to change the available force at run-time. The value of maxForce should always be zero or positive (the default value is 10 N). A small maxForce value may result in a motor being unable to move to the target position because of its weight or other external forces.
