Robotic Arm

The base itself is made out of two aluminium circles. One of them has a hole drilled in the middle which enables servo control horn to be attached to the arm construction. The servo itself was glued between plates that were connected with bolds and nuts. Subsequently all cables from servo motors were wired to a board where an 8-link cable was soldered. This cable connects to the control box.

So, what does the control box consist of? The interior of the box includes Arduino and potentiometers that directly control the arm movements. That is one option. The other one is to use a USB port and use the serial communication to control the Arduino with preloaded code.

The last missing part is a gripper. It was ordered from the internet. The gripper is attached to the top of the robotic arm using an aluminium piece.
