This was a robot I made when I was in the 9th grade during highschool. It is a bluetooth controlled mobile robotic arm. It can hold objects and move the around. I used servo motors to make the arm. I programmed an arduino board and used an H-Bridge controller to drive the motors. This is the 3D model that I made using 3DsMax I made before printing all the parts.
Then I made it real using my reprap 3D printer.
Although this project is completed and I was able to drive the robotic arm using my phone via bluetooth. In fact I don’t have any videos of it except for the short video below that I recorded while building the robotic arm.
