    Also going back to the previous posts a bit, Robodojo is a great place to fight for feathers without going into big melees if it isn't too far north for you.
    Thanks, really need to post the updated design here, as I've been tweaking the design a lot. Sadly Robodojo is too far for me to get to from Dover. Fingers crossed once this pandemic is over and I've moved in with my boyfriend up north I can attend Robodojo as my boyfriend lives closer.

    Like I said to Andy this is a rather old version of the cad the belts was basically running on wider pulleys on one side but the updated version has it basically running the pulleys like in CSB 2.0, currently I'm experimenting to reuse the old drive.

    The drive in the cad above is BaneBots p61 gearboxes running 11:1 with a Propdrive 42-48 650kv motors.

    Updated CAD of CSB 2.1 trying out a version using the old drive set up and thicker side panels.






    The two different drive setups. The left side is a copy of CSB 2.0's drive set up (propdrive 50-60 270kv with 5:1 spur gear reduction) and a possible new drive on the right.

    It's doable, but why?

    protects them more, if you have another neon style event you be able to keep driving tho without one set of wheels

    That's true.

    ONE YEAR LATER:

    Whoops has been a while. Lots of progress has been made since my last post.

    Starting off here is the up to date CAD of CSB 2.1, I revised the back so the back of the bulkheads are not sticking out so far. This has resulted in a Biteforce style back end. In the end I went with the brushless motor and BaneBots gearbox for the drive for simplicity of mounting it.

    I've been ordering parts and materials since April and was slowly making the first parts of CSB 2.1
    Starting of with the 20mm HDPE bulkheads. Progress was slow due to my time being dedicated to my Beetleweight CSB: Echo which was being readied for the Chatham Challenge Belt.

    While working on the HDPE parts the Aluminium and Hardox panels arrived from EMSEA. I've opted to use Aluminium in place of hardox in select areas to keep the weight down. The 11:1 Banebots P61 gearboxes were modified so they could be face mounted with the Aluminium plates.

    This was where I got up to before attending Chatham and moving in with my boyfriend a few weeks later.

    Post house move:

    After moving Cumbria to live with my boyfriend work recommenced. The slot and tap approach to the weapon housing made the test assembly easier after fitting most of the old mechanism into the new robot. This time getting everything correct. With the bolts, nuts, etc arriving I could begin to bolt the robot together. Here you can see the Aluminium slots that help support the dead shaft attachment to the bulkheads.

    I started making the side panel supports that also have slots to allow the drive belts to pass through.
    With the threaded inserts attaching the dead shafts and lids was now fully possible.

    The motors are ready to be mounted in place once the m5 nyloc nuts arrive. And with that you are up to date with the build the next step is make the side panels and refine their supports to get them to sitting right on the robot.
