Group project | 2023 Summer | 3 months
Collaborated with Yuke Yang


Our project name, Infinity, is taken from Buzz Lightyear's famous catchphrase 'To infinity...and beyond!'. Under the name infinity, we wanted to create a kart that was both fast and rugged enough to ride the pavement. Instead of the traditional way of building a go-kart, we utilized a hand-held drill as the primary means of powering our kart and used wood as the main material to build our kart.

step 1


• Cool & Minimal

• Elegant & Streamline

• Ergonomic structure

• Less weight & Faster speed

step 2

1:8 Model 

• Use a Laser cutter to cut out pieces and glue them to see the basic shape.
• Testing the basic arrangement
• Figure out the right proportions
• Found problems with previous thought on rear and front gears and decided to add these after the main structure.

step 3

Making parts

Making necessary parts for steering and motor by using...

• AI drawing (dimensions & precise cutting)

• Band saw

• Table saw

• Metal cold saw

• Wood & Metal Drill 

• Metal lathe

• Sanding machine

step 4


The next step is to make the steering part by using...

• 3D modeling (dimensions) 

• Metal welding

• Sandblasting

• Spray paint

step 5


We decided to power the kart using a hand drill for its lower price and future use in other project.

We use chain to connect the drill with the wheel as a motor system.

step 6


• Quick work on building the large frame out of solid wood and plywood. 

• Test seat and steering wheel height and position

• Get necessary data for the overall bodywork.

• Design steering structure and brake structure on the top side.

• Made a straight L-shaped block with one end for hand grips. When the hand lifts the device, the other end of the device touches the tire to provide friction, thus acting as a brake.

step 7


• Use Solidworks for precise model building using CNC and multiple adjustments.
• Through weight reduction, improved ergonomics, and a unified design language

• Iterated the design to achieve better presentation and functional improvement

• Functional and aesthetically pleasing

step 9

Final model (1)

• CNC the main pieces and then fix some tolerance problems by hand sanding holes to ensure a close fit.

• Check if the new design is ergonomic and functional.

• By anchoring pieces with slots and screws, the final work is much stronger and lightweight than the previous one.

step 10

Final model (2)

• Add slot for the brake to improve the functionality

• Laser patterns to enhance visual effects and increase aesthetic details 
• Separate layers by masking different layers with distinct colors

• Add a bumper strip at the back to prevent a collision

• Add ornamental tail fins to balance the weight between the front and back.


Final model



• Had hard time learning how to break down building a karting kart into small steps.

• Spent time on model iterations for ergonomics and aesthetics.

•  Like exploring new things and new areas.
