Getting more into the details, the steering wheel will be waterjet with the words "Eli Kart" on it, then welded together. There will be brakes on the back wheel, but the throttle is yet to be determined. However, both throttle and brakes will be hand operated. Other parts of the steering mechanism are waterjet and assembled with t-nuts, as you might be able to tell from the picture above. The controller is a Kelly KBS KBS48121 with the high speed option (allowing up to 70,000 ERPM), and I will probably install external hall effect sensors on my motor so I can control it.
This has easily been the biggest design project I've done. Luckily, doing all of the designing in Solidworks will make it very simple to build. Apart from the welding and machining a few parts myself, all I need to do is waterjet some aluminum plate, and order some McMaster parts. I will be using Eli-Kart in my undergraduate thesis so I'll provide updates when I finish!
