pic: Possible Team 114 Drive Component

[Arefin Bari]

First of all, I do want to point out that the person who designed this has put a lot of time into it. It is a very nice concept. but there are few things that caught my eyes and can be modified to make it better (this is where i need the engineers and mentors to correct me if i am wrong).

1) the Drive shaft on the wheel? is that going through 3 bearings (looks like there are 3 plates). if it is, thats BAD. you want to fit everything between two plates. (I can be wrong about this one, I was taught to never put 3 bearings on the same shaft)

2) looks like, the front, back and top sides itselves have 36 hex head screws. Dont you think it can be reduced down? maybe use only 16 screws? why not take a few aluminum L brackets (8 should be good) which are 1/8th thick and use them to hold all sides together (2 on each side).

The overall concept is great. A few tweaking might help you to perfect the design. If you are seeking for help, dont hesitate to ask me or any mentors. Also, if you do want to take a look at a good crab module, you might want to look at "The Navigators (team 79)" crab drive from 2003.

Good luck...
