Robotic Arm Project -- Cup Crane
For this project I was grouped with two other people. Our task was to create some form of a robotic arm that was able to lift up a Styrofoam cup. It had to be at least 18 inches in length. We were given a select number of tools to work with that included cardboard, fishing line, string, hangers, paper clips, rubber bands, tape, and brads. Our teacher gave us $15,000 to spend on these materials. We needed to construct a robotic arm, create and stay within a budget, demonstrate how our arm works, and explain our designing process. Our group got to work and finished right on schedule! This project was interesting because all groups came up different but equally effective designs.
When making our design we thought about cranes that are used in construction work and in skill crane games. We figured it would be hard to build a "hand" that opens and closes like in the skill crane games, so we decided to build a sort of scooping crane. We used hangers, cardboard, tape, brands, and fishing line. We used a small box for the base of our robot and taped a long strip of card board to the top of it to fit the required 18 inches in height. Then we put the brads in the long strip of card board at the bottom for the fishing string to go through. We added a hole the at the height of the long strip of card board so the string can run through to the other side of the robot. We then formed the hanger around the Styrofoam cup so it can pick it up. Then we tied the string around the hanger and put it through the brads to the other side of the robot. Lastly, we added a rectangular hole at the side all the way through to the other side of the robot to put our adjusting rod through to push the scooping hanger onto the cup.
