Welcome to Robotic Arms Wiki!

I found some spare servos a year ago but never got the previous project to work. Now salvaged a broken controller for joysticks and decided to make a new robotic arm. The arm needs some spare metal or weight in the base for extra heft so it won't tip over so easily. Going to replace the sg90 servos with metal gearbox ones soon, big ones already are. Joysticks cahnge the servo position values so they hold position and won't come back when you let go.

If anyone knows a better crapple system or way to make it move than servos, hmu, it doesn't close and open as well as i'd like.

Also if anyone knows how i can translate a potentiometer input better than (value -520)/10 then also let me know, the graplle up down movement is limited currently by it (50-150° about).
