The Bioloid Frame F4 extended bracket has the same mounting positions as the F2 bracket. Unlike the F2, with its extra long arms, it allows room for an entire AX-12 motor to pass through it! This is used on a bioloid as a complex ankle, and it can be used in any robotics project utilizing Dynamixel AX-12 robot actuators and brackets.
Looking for metal brackets? We carry Bioloid Frame Metal F4 Brackets, compatible with AX-12 and AX-12+ mounting points.
