Robot Scooter

[Ari423]

Now that the season is over, I was hoping I could get some advice on my Senior Capstone Project for English class (yes you read that right, English class). For my project, I designed a robotic scooter using techniques I learned from my four years in robotics. The main features are a custom single-speed 3-CIM gearbox and a manually-actuated front steering wheel. The biggest thing I'm concerned about is whether or not it will structurally be able to take the load of a person (~150 lbs) standing on it. (I know it's missing the handle crossbar, I didn't have a chance to add that in)

Some specs on the gearbox:
3 CIMs linked together by 60t idler gears
11:84 spur gear reduction, 15:36 sprocket reduction
6" pneumatic wheel
7.61 ft/s free speed, 6.17 ft/s adjusted

You can see the website I made with more details on the project (made for a less-technical audience) at arimb1999.wix.com/robot-scooter and the more detailed CAD model here.

I am very open to any criticism both for my own learning benefit and for my project grade. Thanks in advance!
