Project Goals
Construct a go-kart frame
Create a functioning ESC/motor controller
Create a functional electrical system
Integrate all systems into a full go-kart
Build Stage: Prototype Fabrication
Mounting front wheels
Mounting components (brake, pedal, motor)
Mount steering and adjust tie rod lengths
Design
Mounted components
Pedal
Electrical
Redesigned PCB to accomidate quality of life components
Fabrication
Mounted motor and began chain work
Mounted front wheels
Mounted steering rack
Testing
Tested steering adjustments on tie rods
Brake caliper
Problem Solving
Front wheels glue is too weak to support our weight
Print brackets to mount it
On actual prototype, we will shorten the lever arm
Steering rack interfering with panel
Reprint it to mount higher
Steering rack doesn't have support
CAD 3dp bracket to eliminate universal joint mobility on upper joint
Gas pedal and steering rack
ESC Quality of Life Components
Mounting wheel with 90 degree pipe
Problem: The hot glue isn't holding the wheel
Solution: Print bracket. On actual cart, we will weld and shorten the lever arm so there is less torque acting on it.
Problem: Tie rods are the wrong length and wheels aren't aligned
Solution: Adjust them because the reverse thread allow you to loosen without taking the whole thing off.
Tie rods are reverse threaded so they're adjustable
For our Go-Kart project, we thought it would be best that we split up the necessary work by our respective interests.
Charlie is in charge of designing and building an ESC with Hunter. He is now working on more quality of life components like servos and switches that we can configure later.
Tyler and Hunter are the ones most primarily working on the fabrication of the Go-Kart. This week, the front wheels were mounted and steering was mounted. We used 3dp mounts for the steering rack and front wheel pipes.
We can finish mounting components next cycle, hopefully. The steering wheel and brakes should be ready.
