Abstract: Implementations relate to detection and mitigation of potential collisions with a user control system. In some implementations, a method includes detecting an object in a sensing field of a sensor of a user control system, and the user control system includes a control input device. The control input device is in a controlling mode in which manipulation of the control input device activates a function of a manipulator device. The method includes determining that the object is an unidentified object and determining a characteristic of the object including a location with respect to the user control system, a velocity, or a trajectory. The method determines whether the characteristic of the object satisfies a condition corresponding to the characteristic, and exits the controlling mode in response to determining that the object is an unidentified object and that the characteristic satisfies the corresponding condition.

Abstract: Implementations relate to actuated grips for a controller. In some implementations, a controller includes a central member, a grip member coupled to the central member and moveable in a grip degree of freedom, a shaft coupled to the grip member, and an actuator coupled to the shaft and operative to output an actuator force on the shaft. The actuator force causes a grip force to be applied via the shaft to the grip member in the grip degree of freedom.

Abstract: Implementations relate to control switch position sensing across a rotational joint. In some implementations, a control input device includes a base member and a roll member rotatable about a central axis with respect to the base member in a roll degree of freedom. A switch contact portion is rotatable with the roll member and moveable to multiple positions in a switch degree of freedom. A first sensor element is coupled to and moveable with the switch contact portion and can be a passive element. A base sensor element is coupled to the base member and configured to sense a proximity of the first sensor element to the base sensor element, and to output a signal indicative of a current position of the switch contact portion in the switch degree of freedom independently of a rotational orientation of the roll member in the roll degree of freedom.
