METHOD AND SYSTEM FOR ELECTROMECHANICAL SAFETY FOR ROBOTIC MANIPULATORS
An apparatus includes a base and a robotic arm operatively coupled to the base via a connector. The robotic arm includes a set of links interconnected by a set of joints. A first link from the set of links is operatively coupled to the connector. Each joint from the set of joints includes a brake from a set of brakes, each brake from the set of brakes configured to be enabled or disabled. The apparatus further comprises an end effector operatively coupled to the robotic arm via a second link from the set of links different from the first link. The apparatus further comprises a controller, communicably coupled to at least one of the base, the robotic arm, or the end effector. The controller is configured to cause the robotic arm to perform a task, and determine, during the task, that movement of the robotic arm is to be restricted.
1 . An apparatus,
comprising: a base;
a robotic arm operatively coupled to the base via a connector, the robotic arm including a set of links interconnected by a set of joints, a first link from the set of links operatively coupled to the connector, each joint from the set of joints including a brake from a set of brakes, the set of brakes including a first subset of brakes and a second subset of brakes, each brake from the set of brakes configured to be enabled or disabled;
an end effector operatively coupled to the robotic arm via a second link from the set of links different from the first link; and
a controller, communicably coupled to at least one of the base, the robotic arm, or the end effector, the controller configured to:
cause the robotic arm to perform a task;
determine, during the task, that movement of the robotic arm is to be restricted; enable the first subset of brakes in response to determining that movement of the robotic arm is to be restricted; and
disable the second subset of brakes in response to determining that movement of the robotic arm is to be restricted.
