I Built a 3D Printed Military Robot

Clever, using an every-2nd-tooth sprocket to avoid interference between the sprockets and the heads of the tread-block screws.

Hello,

I recently built a mobile, military robot optimized for use in desert environments which can be controlled remotely or autonomously and can collect/ stream video to a VR headset via its front mounted camera. The method of movement is a continuous track, created using steel roller chain connected by fasteners with 3D printed links. These loops sit on a custom designed drive sprocket and idler sprocket with 4 shock absorber loaded roller pins that act as the suspension system.

Thank you!

That's great!

Is it possible to share your 3D cad?

I would like to give it a try when possible

Great work, but...

... for a robot that big, why do you need amortization?
