Recently I decided to start a new project, a tank with a heavier weight and larger dimensions, with many car parts received free of charge from car services.
For this project I bought a 2mm sheet metal, I got wheels (wheels with bearings from car distribution for free from car services), sprockets and chains as well.
I will try as much as possible for this project to be made entirely of metal, apart from electrical components.
In the end I estimate that it will weigh somewhere at 120-150 kg, and for propulsion I will try to use two 250w 24v motors, connected together to a gearbox with 3 + 1 gears from a motorcycle then connected to a differential and finally we reach the tracks.
