Engineering Drawings

Below are the dimesions of the second and third layer of our chassis. The top layer was not needed, since it was the same length, width and height as the bottom layer. Each layer was laser cut using plywood that was supplied to us.

These supports were created in order to fix the second layer of the chassis to the top layer. This was 3D printed with holes that allowed for screws to drill into each layer of the chassis, making them rigid.

The rack is another name for the arm of our lever that enters the payload. This portion of our OTV is the part that will be moving vertically up and down in order for us to successfully connect to the two nodes and detect the duty cycle. The bottom of the arm will contain the magnetic sensor, whereas the body will have the wiring and motor going through it, which will ultimately power the movement.

Our motor mount is a 3D printed piece that is screwed to the bottom layer of the chassis. The main function of this is to hold both of the motors in place, which will then attach to the two wheels on the outside of the mount.

The lower back support was created to attach the bottom layer of the chassis to the second layer. This is also 3D printed with holes in order for screws to hold the two parts together. This design is different from the upper support due to the chassis layers having a different design and components attached.

The lift is the base of our lever arm that interacts with the moving rack. This part ultimately stabilizes the rack, restricting it from detaching from the whole OTV. There are jagged marks inside of the lift that interact with the rack, allowing it to move at a steady and calculated pace.

The final design of our OTV shows each of the separate parts integrated together to form the final product. The dimensions below show our success of creating a small and compact OTV.
