A robotic wrist for a robotic arm includes a hybrid differential with a first cam, a second cam, a first differential input, and a second differential input. The first cam and the second cam are disposed about first and second pivots oriented along a first rotational axis. An abduction output is coupled to the second cam and has a second rotational axis transverse to the first rotational axis. The robotic wrist includes a first actuator, a second actuator, a first link coupling an output of the first actuator to the first differential input, and a second link coupling an output of the second actuator to the second differential input. Synchronous motion of the actuators causes flexion of the abduction output about the first rotation axis, and asynchronous motion of the actuators causes abduction motion of the abduction output about the second rotation axis.

An actuator for a robotic joint includes an actuator housing. A motor is disposed within the actuator housing. The motor includes a stator that is rotationally fixed relative to the actuator housing and a rotor that is rotatable relative to the stator and actuator housing. An output shaft is coupled to a rotational motion of the rotor by a gear reducer. A first rotary encoder is coupled to the rotor to measure one or more parameters of the rotational motion of the rotor. A second rotary encoder is coupled to the output shaft to measure one or more parameters of a rotational motion of the output shaft.

Robotic joint actuator

A method for photographing at least a portion of a subject is disclosed, the method comprising: generating a photography scheme, the photography scheme comprising a set of photography control points, each of the photography control points comprising: a location of the platform relative to the subject; an orientation of the platform relative to the subject; and one or more photography parameters; determining a location and an orientation of the platform carrying the imaging system; navigating the platform to each of the photography control points and operating the imaging system to capture an image of the subject at each of the photography control points according to the associated photography parameters. A method of administering photodynamic therapy to a subject is also disclosed.
