SolidWorks Parts and Assembly

The prototype is somewhat successful in its current state.  The laser cut top and bottom plates work nicely as a frame and mount the servo motors in appropriate positions.  The catapult arm itself, also laser cut, works properly and demonstrates smooth motion.  The groups biggest issue is properly controlling the servos to work in accordance with each other.


Here is a video go-around of our prototype.  The servo filmed moving is the motor for loading the elastic band (not shown) to pull the catapult arm.  The rear servo filmed not moving will release the spring-loaded arm.

Below are models of the individual parts laser cut for the prototype, as well as a 3D model of our servo motor to be mounted.

-Team Thumbs Down

First update on the project. We decided to go with a catapult style launcher. Here are some of the assembly pictures:

We are finalizing the size of the two servo motors we are going to use to apply the tension and release the catapult.

Project Goal

Arduino Catapult 1

Arduino Catapult 2

Our goal for this project is to design some type of catapult involving a push button start for the programmed arduino, which will trigger the release, and possibly tension a spring or control an additional element.

Team formed!
