HOW TO MAKE THE ROBOTIC ARM PART 1

These are the items needed to make the mechanical part of the robotic arm:

 Procedure:

1) Cut the curtain window rail into these specific measurements:
    2x30cm
    1x26cm
    2x20cm

2) Drill some holes about 5mm in diameter

3) Spray the curtain window rail

4) Put in the bolt and nut into the hole to combine the rail. This is the main frame of the robotic arm

5) Cut the front part of the spatula and drill some hole. Put anything to the spatula that may increases it grip

6) By using bolt and nut connect the front part of the spatula. This will be the gripper of the robotic arm

7) Weld three bolt onto three different gear box motor

gear box motor for gripper

 

gear box motor for lift

gear box motor for base

 

 8) Attach two gear box motor to the frame of the robotic arm by using cable tight. The first at the top and the second at the bottom.

9) Drill a hole on the remote control car. Then put one of the gear box motor with bolt into the hole. Screw the gear box motor tightly.

10)Then attach the robotic arm to the remote control car by using nut. Make sure there is a bracket between the nut. So that the robotic arm is attach straightly

11)Put 10 limit switches onto the robotic arm and remote control car, based on specific locations. 

12)Finally, tie 2 fishing line thread like shown in the picture below. One for the lift and the other for the gripper. Make sure it is very tight.
