The Industrial Robot named "MECHRO" designed to pick and place objects of maximum one kg and used in the Automotive and Electronics Industry using "SCARA CONFIGURATION". The distinct parts of "Mechro" are the upper arm, lower arm, the gripper and base. The arms are made of Aluminum and its houses the drive system consisting of motors, sprockets, chains and gears. This facilities the programmer to write the control programme in any convenient language. The Gripper assembly was tested and the following results were inferred. The Gripper opening and closing was found to be 0-35 mm. The roll of the Gripper was 360°. For every revolution of the gripper the M-12 screw advanced by 1.7 mm (pitch) giving the vertical linear movement of the gripper. Next the rotations at the axes were examined and the rotation of the elbow axis was found to be equal to 255° and at the shoulder axis 360° rotation was obtained. The gripper was found to grip a load of 1 kg. The robot is command to move 20 inches and the actual move is measured and found to be 19.99 inches. The error is ± 0.01 inch and can be represented as an accuracy error of 0.05% less than the commanded distance.
