Even tracked vehicles have difficulties getting through eg mountainous terrain.
I guess that’s one reason why the robotics industry is working so hard to create multi-legged robot vehicles.
Today’s invention is a hexapod transport platform with a twist.
Six small mechanical diggers are backed into a chassis (blue). This locks onto their wheels so that the diggers’ bucket arms are sprung with respect to the chassis.
The blue unit also contains some servomachinery which can manipulate the diggers’ controls -under direction from a driver in a forward-facing cockpit.
In this way, the diggers’ buckets can be made to step in sequence over very rough ground, allowing the chassis to carry troops, food supplies or other equipment.
