METHOD AND SYSTEM FOR ELECTROMECHANICAL SAFETY FOR ROBOTIC MANIPULATORS
A robotic system includes a robotic arm that interacts with an object during operation. It further includes a locking component that, during operation, locks a multi-position component in an operating position. Responsive to a triggering event, locking of the multi-position component in the operating position is released and the multi-position component moves away from its operating position, facilitating separation between the robotic arm and the object.
1 . A robotic system, comprising:
a robotic arm that interacts with an object during operation; and
a locking component that, during operation, locks a multi-position component in an operating position;
wherein responsive to a triggering event, locking of the multi-position component in the operating position is released and the multi-position component moves away from its operating position, facilitating separation between the robotic arm and the object.
2 . The robotic system of claim 1 , further comprising a damper that regulates a speed at which the multi-position component moves away from its operating position.
3 . The robotic system of claim 2 , wherein the damper is associated with a damper rate that based at least in part on a specified amount of time to move the multi-position component away from its operating position.
4 . The robotic system of claim 1 , further comprising a spring that causes the multi-position component to move away from its operating position.
5 . The robotic system of claim 4 , wherein a spring force exerted by the spring is specified based on a maximum permitted force from a user.
6 . The robotic system of claim 4 , wherein during operation, a holding force of the locking component counters a force of the spring that is directed to moving the multi-position component away from the operating position.
7 . The robotic system of claim 1 , wherein the multi-position component comprises at least one of a rotating joint, a prismatic joint, or a linkage-based component.
8 . The robotic system of claim 1 , wherein the locking component comprises an electromagnet.
9 . The robotic system of claim 1 , wherein a holding force of the locking component is based on a force associated with applying massage content.
10 . The robotic system of claim 1 , wherein the multi-position component is coupled to the robotic arm.
11 . The robotic system of claim 10 , wherein the robotic arm is coupled to a base plate, and wherein the multi-position component is coupled to the base plate.
12 . The robotic system of claim 11 , wherein the multi-position component comprises a pivoting joint located at the base plate.
13 . The robotic system of claim 1 , wherein the multi-position component is coupled to a support structure that supports the object.
14 . The robotic system of claim 13 , wherein subsequent to release of the locking on the multi-position component, the support structure moves away from the robotic arm.
15 . The robotic system of claim 13 , wherein the support structure comprises a platform that supports the object.
16 . The robotic system of claim 1 , wherein the triggering event comprises user activation of an emergency stop.
17 . The robotic system of claim 1 , wherein the triggering event comprises a power outage event.
18 . The robotic system of claim 1 , wherein a range of motion of the multi-position component is limited by an end stop.
