Description

• The GEARWURX ARM 3.0 improves on the ARM 2.0(DISCONTINUED) with better position sensors, more robust linear actuators, and more powerful motor controllers.
• This 6 degree of freedom arm uses linear actuators and rotary servos to provide an operation envelope of over 7 ft in diameter.
• Sealed ball bearings provide precision movement at each joint.
• The lower 4 joints use absolute encoders for precise, linear control.
• Typical current draw at full capacity is approximately 7 amps. Rotation speed of base joint is 60 degrees / second.
• Wrist rotates 240 degrees in 2.3 seconds.
• Gripper moves from fully open to  fully closed in less than 1 second.
• A power switch with green LED “on” state indication is located on the electronics enclosure.
• See below for mounting pattern and refer to datasheet below for signal pinout and additional information.

ARM 3.0 Closed-Loop Position Control:

• All joints operate in a closed loop position control mode.
• All joints are PWM ready if you choose to command from your microcontroller or from an RC radio.
• All joints utilize absolute feedback.
• This version of the ARM is best suited for applications where the ARM will be under computer control.
• And where the computer will send a PWM command to the each joint of the ARM to go to a specific position.
• The GEARWURX ARM 3.0 will then hold that position.

ARM 3.0 Open-Loop Velocity Control:

• All joints in this version of the ARM operate in open-loop velocity mode.
• This ARM is most friendly when using a joystick or radio control unit to allow a human operator to directly control the ARM.
• This version of the GEARWURX ARM 3.0 can run out-of-the-box by connecting 12VDC power and any standard RC radio to the input connector.
