Robotic arm with coding and physics explanation

Presently, the robotic arms are used in various industrial applications like fixing of parts and assembling of the motherboards etc. which seeks the human power power in large scale but are done easily by these robots with certain range of higher accuracy. DIY Robotic Arm Here, we are going to see how to make a "DIY Robotic Arm",  which is the miniature size of the industrial robotic arm in a completely working state along with the coding written in  Arduino software. Few months back I was trying a simple robotic arm. But practically working is not posible.It's effeciency is only 53% Now we are going to see a fully completed Robotic arm with 17 stepper motor Come!! let's see how the robotic arm is working Buy the components at better price from here๐Ÿ‘‡๐Ÿ‘‡ 1.
