Wrist Kit, with Three Degrees of Freedom
Robotic wrist kit, with three -- count 'em!, three! -- degrees of freedom (technically, radial flexion-ulnar flexion and flexion-extension movements of the wrist, and pronation-supination of the forearm).
The wrist kit works with most any standard size R/C servo -- three are required. The servos are not included.
Made to work with the gripper kit.
With four servos at about $12 each, you can build a sophisticated 4 DOF (degree of freedom) end-effector for under $60 -- a bargain no one else offers.
Available as gripper only, gripper/wrist combo, or gripper/wrist combo with four servos.
