[0069] Still referring to FIGS. 8-12, a distal end of each of the plurality of hand linear actuators 50 terminates at a different axial position, when each of the plurality of hand linear actuators 50 are in a fully retracted position (as shown in FIGS. 8 and 9). Specifically, when each of the first subset of hand actuators 50c and the second subset of hand actuators 50d is in the fully retracted position, the distal ends of the second subset of hand actuators 50d are arranged axially further from the flange 160 of the first housing section 154 than the distal ends of the first subset of hand actuators 50c. This axially-staggered arrangement of the plurality of hand linear actuators 50 further aids in packaging more linear actuators within of the robotic forearm assembly 12 and facilitates access between the plurality of hand linear actuators 50 and the corresponding joints in the wrist assembly 14 and the hand assembly 16. [0070] The operation and control components of the robotic forearm assembly 12 of FIGS. 8-12 is similar to that of the robotic forearm assembly 12 of FIGS. 1-7 described herein. For example, the robotic forearm assembly 12 shown in FIGS. 8-12 includes the one or more linear printed circuit board assemblies 84 and the rotary printed circuit board assembly 96 that are both arranged internal to the housing 150. The rotary actuator 42, the plurality of hand linear actuators 50, and the wrist linear actuators 52 are each independent controlled by a respective one of the linear printed circuit board assemblies 84 or the rotary printed circuit board assembly 96 to selectively move one or more of the joints in the wrist assembly 14 or the hand assembly 16.
