Description
Robotic Arm
This my DIY robotic arm which is made up of foam and double sided tapes. There is an arduino uno r3 for the code. It is connected to two motors via drivers. The DC BO motor turns the arm right and left. The DC stepper motor turns it up and down. There is also a Q-box processor which is a custom driver thingy only avaliable in the QuadStore where I got most of my products from. It is only used for the power source since I only had a 6v barrel jack battery. It also connects the gnds togther. There is a metal part on the hand help with screws used the push buttons. there is also a breadboard which has an IR reciever to control the robotic arm with an IR remote.
