Robotic Arm

Project Manager: Pneumatic System & Electrical Circuit Wiring

Role: involved in pneumatic system design and hardwiring of electrical components

The Robotic Arm is a crane-like structure with truss linkages. It was designed to rotate 180 degrees and translate horizontally with speeds up to 25 in/min (635 mm/min) utilizing a motorized ball screw system. A vertical Z-Axis using a pneumatic cylinder and vacuum gripper will also be designed by the students and added to the main structure of the Robotic Arm. Once completed, the Robotic Arm will be able to precisely pick up alpha-numeric tile from any given height and stack it onto a turntable table top without toppling.

The Robotic Arm is controlled by the operator using pushbutton, switches and knob mounted on the control box. This control box is electrically linked to the Robotic Arm via cable. A momentary-momentary switch controls the motor driven ball screw system, causing the Robotic Arm to extend and retract. The extension or retraction speed is regulated via a motor controller. The total travelled distance by the ball screw system is monitored by two limit switches; one at the fully extended position and the other at the predetermined retracted position. Each limit switch is equipped with a red LED light to indicate when the travelled limit has been reached. The extension and retraction of the Robotic Arm can be done in either Manual or Auto modes.
