Collision Sensor

If you want to provide feedback about the interaction of bodies during a simulation, you can attach a Collision Sensor to geometry to monitor parameters and trigger events. Use the status of a collision sensor to trigger condition statements or advanced mechatronics commands.

You can select different collision shapes to encapsulate the component to form the detection area. If necessary, you can change the orientation and origin of the Box, Line, and Cylinder collision shapes to increase their physical accuracy and reduce unwanted detections.

You can specify whether the collision sensor is active only during a detection, or whether the sensor state changes each time a detection occurs. You can also specify whether the collision sensor is triggered only by collisions with a body of a specified category, or if it can be triggered by collisions or clicks.

Use with advanced mechatronics commands

Use collision sensors with advanced mechatronics commands to do the following:

• Trigger the start or stop of operations.
• Trigger the change of a runtime parameter. For example, changing the speed of an actuator.
• Create counters within runtime expressions.
• Trigger the exchange of rigid bodies.
• Trigger changes of visual properties.
