A two joint module includes a housing and a pair of hollow rotary actuator assemblies. Each actuator assembly has an axis and a hollow shaft and the axes are arranged at an angle to each other. The pair of hollow rotary actuator assemblies are arranged back to back and attached to the housing such that cables can be fed from the outside of one of the pair of hollow rotary actuator assemblies to the inside thereof and to the inside of the other of the pair of hollow rotary actuator assemblies to the outside thereof. The disclosure also relates to a robotic arm. The robotic includes at least two two joint modules as described herein and at least a first link.

The present invention relates to an automated grading process and apparatus for grading an animal carcass. The process includes the steps of generating and receiving signals; determining the location of the ribs in the carcass therefrom; determining a predetermined reference point on the carcass; determining a probing location; and probing the carcass. As an example the predetermined reference point may be the first rib and the probe location may be between the third and fourth ribs. The present invention also includes a method for determining the location of the ribs and a method for determining the first rib. The apparatus includes a base, a clamping sub-system for positioning the carcass and a sensing-probing subsystem. The sensing-probing subsystem includes a signal generator and a signal receiver each directed at the clamped carcass; a method of determining the location of the ribs; a method of determining a predetermined reference point on the carcass; a method of determining a probing location; and a probe. The probe is attached to a robotic arm.
