I'm guessing that one of the reasons is to make a prototyping bot to put things on top of. I'm having trouble imagining what would happen if the prototyping robot happens to not fit a specific design. Has this kind of thing been done before?
Now, on to the actual CAD: - How do you guys plan on mounting bumpers?
- Access to the chain or the inner side of the shaft is blocked. If this things is suppose to run for years and years, maintenance is more important than it is for a regular FRC robot.
- er, I'm going to assume the battery mount isn't finished yet either
- you can use something like Versaframe instead to increase mounting versatility
- What resources/tools does your team have to make something like this?
Btw, is that the black anodized 80/20 from mcmasters? Nice touch.

Part of the reason for a dedicated outreach bot was because we wanted to build a t shirt cannon module. The modularity can allow to change the robot abilities quickly depending on the outreach event. We also thought it would be useful to have a base so that while prototyping during build seasons we would be able to have driving prototypes quickly to test basic concepts and allow the programmers to start working much sooner. We felt that the drive base design was simple enough it should work for a good amount of conditions and designs. Obviously designs will differ from a purpose built robot for a game but this can let us quickly test basic ideas Ex. For Stronghold we could have built various shooters and then decide which one we thought would work best.
Bumpers are probably going to mounted similar to how we've built most of our bumpers either pins or bolts on c or angle mounted to the frame. If you go to the CAD there are bumpers, they were taken off for this render to let you see the inside more easily. With the bumpers on the only part above the bumpers is the 80/20.
The access to the chain can be done from over or underneath. The motor controllers do not actually go over the chain and the spacing will be placed such that maintenance should be fairly easy.
The battery mount is fairly close to done actually. The strap isn't shown in the cad and the rear angle hasn't been placed yet but the battery was placed like that to make it easy to change without having to remove any modules that may go on top of it. After this years robot we wanted a battery that could be changed by one person very quickly.
We are using Versaframe for most of the extrusion in the frame.
Resource wise we have everything we need to make a WCD frame (Mill, Lathe, Drill Press, Pneumatic Rivet Gun, Etc)
The 80/20 was actually donated to us by a sponsor.
Thank you for your comments. I hope this helps to clear things up a bit.
