<p>A robotic crash protection device (10) is adapted to be interposed between a robot arm and a robotic tool for detecting a crash. The device includes a housing (12), a piston (20) having a generally central bore (22) movably mounted within the housing (10), an actuator (40) for engaging the piston (20) and moving the piston (20) in response to a crash, and a switch (46) disposed within the housing (10) and generally aligned with the bore of the piston (22). The switch contacts (48) are disposed such that in a default position the bore of the piston (22) engages the contacts (48) and maintains the contacts in one switch state, and in the event of a crash the piston moves and permits the contacts (48) to assume the opposite switch state. A non-circular contact surface (21) between the actuator (40) and the piston (20) ensures a consistent response to lateral forces applied in to the axial direction in any radial direction.</p> |
