Post from Fall 2013 - Independent Project Period

Fall 2013 - Independent Project Period | Projects | Prop Car | Updates

  •       Yesterday, We chose to branch off from our Minibot to work on another project. We did this because we lacked materials, and it will take a few days to come. We had many ideas, until we thought of building an RC plane. This project wasn't quite enough, so we chose to mix our two ideas. We got the idea to build a propeller powered car. 

             At first, we wanted to build it out of foam, but we found foam was too light and couldnt support the propellers. Then we just chose to build it with wood. With our idea in mind, we designed it on Rhino. The car resembles a space ship. We cut two lines of triangles down the middle, which surprising reduces the weight by about 40%. The propellers will be mounted on the rear, where the fins go out. We also needed to raise the RC propellers, since they were about 7 inches long. We designed inserts on the main body, and made a rectangular platform to stand up. We put extrusions on the sides to stop it from going through, and holes for the RC motor to attach. We also added triangles to support the platform.

               After the design, we printed all the parts. We assembled with wood glue, supports/interlocking parts, and screws. The car will be mounted on three RC plane wheels, One in the front, which will be controlled by a servo, and two for the rear wings. These wheels are easy to work with, and extremely lightweight. We are attaching the wheels with the wire, clamps and glue. The RC motors have 5000 hp each. We are mounting 7 inch propellers that should easily propel this car forward. We will mount these motors to the wood platforms on the wings. We will attach them with the servo screws, which fit perfectly. 

          After we assemble this completely, we will program the servo and motors. We will also have to set up a MAX file to let us control the car by remote. Then we can test it!!!
