This project is about designing and building a BIG custom remote controlled tank, from scratch.
It will be about 300KG (600lbs) ; 1.5m (5ft) long ; 0.6m (2ft) high and 1m (3ft) wide, which corresponds to a 1/5th scaled Main Battle Tank (MBT).
It won't be a scaled model of an existing tank, but a fully custom design, even though it will look like the Italian ARIETE C1 MBT.
It will be able to shoot paintball pellets and airsoft pellets. It may be equipped with additional functions in the future.
This project is still in development, and will take years to achieve since all the mechanics, electronics, and programming will be made from scratch.
There is no specific purpose other than having fun !
Since I didnt really learn electronics at school, I expectef the radio to be quite difficult to build. but it turned out easier than I thought, it's just a basic button box, with an Adruino, a screen, a 2.4GHz module and a battery of course. The box is 3D printed (SLA) and the pannel is made out of wod, laser cut.
Building the frame wasn't that hard, but much longer than i expected. Mainly because i had to drill hundreds of holes and be very cautious with positioning and maintaining the struds carefully, after some sort of misadventure. The chassis is not finished yet.
The gearbox design has been quite a challenge : I have a lot of mechanical power to transmit (4.8kW) with a high speed on one side and high torque on the other. Not to mention that the gearbox had to be as compact as possible to fit in the tank. I used roller chains instead of gears to make it easier to assemble run and service, as is it my first gearbox project.
