A robot designed for reducing collision impacts during human interaction. The robot includes a robot controller including a joint control module. The robot includes a link including a rigid support element and a soft body segment coupled to the rigid support element, and the body segment includes a deformable outer sidewall enclosing an interior space. The robot includes a pressure sensor sensing pressure in the interior space of the link. A joint is coupled to the rigid support element to rotate or position the link. During operations, the robot controller operates the joint based on the pressure sensed by the pressure sensor. The robot controller modifies operation of the joint from a first operating state with a servo moving or positioning the joint to a second operating state with the servo operating to allow the joint to be moved or positioned in response to outside forces applied to the link.

A control system may receive a first plurality of measurements indicative of respective joint angles corresponding to a plurality of sensors connected to a robot. The robot may include a body and a plurality of jointed limbs connected to the body associated with respective properties. The control system may also receive a body orientation measurement indicative of an orientation of the body of the robot. The control system may further determine a relationship between the first plurality of measurements and the body orientation measurement based on the properties associated with the jointed limbs of the robot. Additionally, the control system may estimate an aggregate orientation of the robot based on the first plurality of measurements, the body orientation measurement, and the determined relationship. Further, the control system may provide instructions to control at least one jointed limb of the robot based on the estimated aggregate orientation of the robot.

A positioning device is adapted for positioning a tool at a setpoint position on a flat substrate in an X-Y plane, the tool exerting a process force in its axial direction perpendicularly onto the substrate. The tool includes a multicomponent force sensor to measure unwanted process-force components in the lateral direction. The setpoint position of the tool is correctable by the positioning device such that the lateral process-force components are minimized.
