Drill Go-Cart Harry Geisenberger

Problem Statement - Our group was given a goal of building and designing a drill powered go cart. Our constraints are that we have a $20 budget, a two marking period timeline, and one of our group members has to be able to ride in the go-cart. We will be judged on how fast it moves, how long the can the go-cart travel, and how well the go-cart maneuvers.

Base Design
Axel Design

Research - Our research was based on image 1 with the bottom having some form of open space to reduce weight. We also will use the side bumpers to keep the driver in the cart. Our research based off image 2 is the axel design in how the front wheels will be the ones that turn and the rear wheels will propel the cart forward.

Base
Brake System

Design - The design in image one is design for the base. We wanted the base to be light weight and be able to hold our driver. The base will be 4 and 1/4 feet long and the cut out 1 and 3/4 in to the base. In image 2 the brake system will be a system of levers. We will run a PVC pipe on the bottom and use connectors to be able to brake on each side evenly.

Build

For our build stage we decided to used the shop bot and V-carve to design and cut out our base of the go-cart. We laid out the top views of our 3-D models on to a blank document to lay out a configuration to minimize wood usage. To be able to cut the wood we created tool paths to guide the shop bot to know where to cut the wood and where to avoid the screws. When I was creating the tool path I decided to use 4 passes instead of 2 due to the risk of breaking the drill bit. We also used different tool paths for items that belong in the joint due the half inch disparity the drill pass would create.
