“A robotic arm made from easily available materials that can record and replay positions.
This is a simple robotic arm that can record and replay positions. It is made from easily available materials, like cardboard and hot glue, which makes it easy to build.
You control the arm with a graphical interface on the computer that sends data to the Arduino that controls the arm. There are sliders to control each servo, and buttons to record positions and replay what you’ve recorded. You can also save and open past recordings.”
