A sensor system includes a first member that extends along a rotational axis and has a surface disposed circumferentially about the rotational axis. A conductive element is disposed on the surface of the first member and disposed about the rotational axis. A second member extends along the rotational axis. A rotational position between the first member and the second member is adjustable. A target is mounted to and rotatable with the second member and is movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is spaced further from the conductive element in the second position compared to the first position. The conductive element detects a change in movement of the target from the first position to the second position for any rotational position between the first member and the second member.

A system including a controller, and at least two agents that communicatively access the controller. At least one of the agents is a robot. The system includes at least one processor communicatively coupled to the agents, and at least one storage device, communicatively coupled to the processor(s), that stores processor-executable instructions which, when executed, cause the processor(s) to: receive first job set of instructions provided by the controller, for a first agent included in at least two agents; and send, on behalf of the first agent, a sham status message before actual completion of the first job. The processor-executable instructions may, when executed, further cause the at least one processor to: update a data store to reflect the first job set of instructions; and receive for a second one of the at least two agents a second job set of instructions before completion of the first job.

Systems and methods of assisting operator engagement with input devices include an input device configured to be operated by a hand of an operator, a repositionable structure coupled to the input device, a hand detection system, and a control unit. The control unit is configured to detect a position and an orientation of the hand using the hand detection system, determine, based on the position of the hand, a target position for the input device, wherein moving the input device from a current position of the input device to the target position moves the input device closer to a grasping position for the hand, and in response to determining that an orientation difference between the orientation of the hand and a current orientation of the input device is not greater than a threshold orientation difference, cause one or more actuators to move the input device toward the target position.

A dynamic planning controller receives a maneuver for a robot and a current state of the robot and transforms the maneuver and the current state of the robot into a nonlinear optimization problem. The nonlinear optimization problem is configured to optimize an unknown force and an unknown position vector. At a first time instance, the controller linearizes the nonlinear optimization problem into a first linear optimization problem and determines a first solution to the first linear optimization problem using quadratic programming. At a second time instance, the controller linearizes the nonlinear optimization problem into a second linear optimization problem based on the first solution at the first time instance and determines a second solution to the second linear optimization problem based on the first solution using the quadratic programming. The controller also generates a joint command to control motion of the robot during the maneuver based on the second solution.
