Few of us will ever find ourselves piloting a full-sized military tank. Instead, you might like to make do with the RC variety. [TRDB] has whipped up one of their own design which features a small little pellet cannon to boot.
The tank is assembled from 3D printed components — with PETG filament being used for most of the body and moving parts, while the grippy parts of the treads are printed in TPU. The tank’s gearboxes consist of printed herringbone gears, and are driven by a pair of powerful 775 brushed DC motors, which are cooled by small 40 mm PC case fans. A rather unique touch are the custom linear actuators, used to adjust the tank’s ride height and angle relative to the ground. The small cannon on top is a flywheel blaster that fires small plastic pellets loaded from a simple drum magazine. Running the show is an ESP32, which responds to commands from [TRDB]’s own custom RC controller built using the same microcontroller.
As far as DIY RC tanks go, this is a very complete build. We’ve seen some other great work in this space, like this giant human-sized version that’s big enough to ride in.
The tank toy I wanted all my childhood!!!
Beautiful
Yeah this would be really fun for a kid, 100%
I can imagine using a few of them in a POV paintball competition being quite good fun.
Perhaps let loose autonomously with a waterpistol to deter cats or birds from a fish pond or similar.
And then the water-nation attacked…
Looks like it is using the same gun-laying approach like the https://en.wikipedia.org/wiki/Stridsvagn_103 – and with great accuracy too! Bravo!
Funny, stridsvagn reads as “strijd wagen” in Dutch, so combat wagon like the wikipedia article says. Also from the wikipedia article i now understand that the linear actuators are needed to aim the cannon vertically.
it’s such a mad over the top build, crazy
