A powered sliding platform assembly may include an actuator, a platform, and a controller. The platform may have a rail defining first and second openings configured to receive a pin of an actuator. The actuator and the rail may be arranged such that while the platform moves between extended and retracted positions, the pin rides along the rail between the openings. The controller may be programmed to, in response to a signal indicative of an object being proximate the platform, inhibit movement of the platform.
