Kit Chassis

Is whether it is worth it for our team as a rookie team, to build a custom chassis? If we did I would thing we would make a box frame like two Kit frames on top of each to strengthen the chassis. We have a mentor who can weld aluminum for us, and some of my classmates could come up with a design easily in CAD. But I don't think whatever chassis we come up with would be that beneficial as a team with years of experience. Because we are not doing a different type of drive like a swerve drive, there seems like there is not much benefit. We could lose a couple of pounds from various fasteners, I don't know what else. Also, if we have to make a hole in the front for the ball retrieval mechanism, the custom frame could have better reinforcements built in. And it seems that there is not much weight saving from 5052 aluminum to the 6061 1in square tubing with 1/8in walls. We do have several spare hands though, so I could assign the chassis team to work on a new chassis rather than working on the prototypes of the manipulator. Or we could just have our mentor weld the Kit Chassis.

No. It is not worth it to spend your time redesigning the kitbot chassis. As a rookie team, you are going to be spending a great deal of time learning what doesn't work. In this game, your ball-shooter and manipulator is a huge challenge in itself. Go find the 1114 video kitbot on steroids, and take lessons from that on how to assemble your chassis. Then move on and work on ball acquiring and your turret.

You will have more than enough coding and mechanical challenges just trying to put together an accurate and consistent ball shooting mechanism.
