Definitely would be a good idea to make the spacing between the cut outs smaller, for reference I usually do 0.75" spacing, but now for parts of the plate that have nothing mounted on it I am most likely going to do 0.5".
I'm not sure why, but I always seem to make the chassis plates higher than the wheels, just to enclose them, I kinda like that it wasn't done here, a lot of weight was saved there, maybe I will do the same next time.
This also looks like a smaller wheel, I think 6" (if those are 8inch wheels that I'm looking at) could also work on this chassis. Not sure If that was planned for them to be interchangeable? But If it is interchangeable (even if it wasn't designed to), and you seem to have a hard time turning sometimes, you could increase the torque by putting smaller wheels on there.
Oh MY! Is that a designed battery box I see there!! WOW! Thats Luxury right there... Prop's to the student for remembering to design that in. After designing our whole robot myself this year, and the off season chassis, that's the thing I forgot Both times...
Over All Great chassis, hope that students knows how well of a job he/she did
