50% scale version of Acorn?

I’m pondering a smaller cheaper version of Acorn

Something on this kind of scale ~1m x 1m frame, 6" hub motors

Using all the electronics of the full-size version.

I realise it wouldn’t save 50% of the cost, but it might be somewhat more accessible

I am wondering why you do not just adapt a recycled electric wheelchair as your mobility unit as they can often be gotten for $100.00 or less and the money can go to the software and electronics.

Because the motors and control system would lack the necessary accuracy.

Tentative BOM

Spotted this one that looks nice and is around the right scale for me. I like the use of aluminum scaffold bar, it’s cheap and widely available in the UK
