This is our week 4 Update.
This is our current design. The climber which goes on the left side of the robot is missing from the CADD file because I don’t currently have access to the CADD Assembly for it. The rest is pretty much how it is at present. I’ll try to get a picture of the practice robot tomorrow to upload.
This is a CADD drawing of our current competition frame. I can’t really see any major changes to it though we will probably add a cross member on the top to help stiffen the middle of the frame.
This is our current fuel delivery system. I’ll upload the CADD files to anyone who is interested. It is designed to shoot from the back of the robot when the front of the robot’s bumper is pressed against the boiler. We are hoping tha this will greatly increase our accuracy.
Do you have a mechanism to ground-load fuel?
Why are there no triangulation elements anywhere in the chassis?
We have a floor intake on the left side of the robot, back side of the robot in this picture. You can see where it goes in the following:

I will post more pictures including of our current practice robot after school today. Our intake is relatively small, and we are hoping to not need to use it too often. Our main goal is to load from the hoppers only using the intake if there are no other options.
Currently gussets aren’t in the design. Depending on testing we may choose to add riveted gussets to a few different parts of the robot if the frame bends at any point particularly easily. We are currently using 1/8th wall aluminum square tube so hopefully that will be sturdy enough.
Our practice frame is currently completed with assembly and testing well under way. We are hoping to be done with assembly of our competition robot by the end of the week. Hopefully that will give us enough time for testing to see if any additional frame strengthening is necessary.
best wishes,
Edoga
You don’t have to go with discreet gussets unless you really want to. Riveting a .032in thick sheet of aluminum (as an example) to the bottom surface of the chassis will add a tiny amount of weight but provide a tremendous/hilarious amount of strength and stiffness.
