摘要
Devices, systems, and methods for controlling manipulator movements include a manipulator arm coupled to a proximal base. The manipulator arm is configured to support an end effector and robotically move the end effector relative to the proximal base. The manipulator arm includes a plurality of joints between the end effector and the proximal base and a processor. The processor is configured to calculate joint movements of the plurality of joints that provide a desired position of the end effector using inverse kinematics of the manipulator arm and when a first set of one or more joints of the plurality of joints is at corresponding joint range of motion limits: determine a constraint based on a relationship between joint movement of the first set and a second set of one or more joints of the plurality of joints and apply the constraint within the inverse kinematics to provide haptic feedback.
