Progress.
New version fits inside a 350 x 350 octagon, which is surprisingly small even when compared to the old test frame which was 260 x 370.
Comparing the old with the new
Another angle, will end up about the same height, maybe a fraction less
Close up, still plenty of space to add various things and make changes in the future.
According to CAD, a full 3.25mm hardox shell would be 7.2kg, just a fraction too heavy, replacing the top lid with 1mm stainless brings it down to a healthy 5.4kg, which leaves a good 1kg for some nasty teeth to weld on
Anyway, gonna go dig this sheet of hardox out and start cutting _________________ https://www.halfdonethings.com/

Started on the new meltyboard, should be just a fraction larger then a spektrum receiver. If this board proves to be more battle worthy then the last, I'll get a decent PCB etched up instead of my horrid rats nest wiring.
MBX: The Future
Got a bunch of ideas lined up for version 0.2b and 0.3, things I want to implement now, but don't have the luxury of having enough time before Ideas Festival (I.F. from now on).
0.2b, essentially 0.2a, but will test a new control method, and test a brushless setup, aiming for 1500RPM. From version 0.2b onwards , I'll be running 100% my own code, right now I'm using about 60% of my own, with core parts written by Rich. My new control design won't work on Rich bits, so I'll be working on my own code for this. Will be happy once I finish this code, because then I can say I designed, built and coded a melty brain 100% from scratch
0.3 will be three wheeled, brushless and use a new control method, aiming for 2000rpm. Translation speed should increase again, aiming for 5km/h linear, which is slow to compared to other bots, but when the whole thing is spinning at 130km/h, it's not that bad.
Pending on the success of 0.3, it will probably be repackaged into a new robot, developed for serious competition. This might take a few years to achieve, but it's a goal I'm extremely interested in achieving _________________ https://www.halfdonethings.com/
