All-terrain robots are supposed to handle a wider variety of terrain than ordinary robots. Whatever type of terrain you prefer (tough terrain, steep slopes, sand, mud, etc.), these robots can provide maneuverability and stability on every point of the terrain.

Many all-terrain robots are quite versatile, but only a few of these could be removed from the average and considered extreme robots.

However, to use one of these robots you don’t need to know electronics and programming. Almost all of these wild machines are remote controlled, semi-autonomous, or autonomous.

This article presents an overview of extreme all-terrain robots on wheels, tracks, and legs.

Extreme All-Terrain Robots on Wheels

1. Grizzly – The BEAR Robot (see it in action here)
   Grizzly is an all-electric robotic utility vehicle engineered to handle a large variety of applications in agriculture, mining, and defense.It is a platform solution for autonomous tasks in agriculture including chemical spraying, cultivation, and mowing. Due to its robustness, in the mining sector the vehicle is used to map and survey mines. As for military use, Grizzly is featured enough to transport autonomously materials to support the soldiers.

   The all-terrain robot offers the performance to carry a payload of 600 kg (1320 lb) at a maximum speed of 19 km/h (12 mph).
   

2. Sand Flea – Jumping over obstacles (see it in action here)
   When you see for the first time the Sand Flea robot, nothing seems suspicious. It seems a cute robot that can be driven like an RC car.On flat terrain, the robot drives like any remote control car with wheels. But with one special skill, the robot jump 9 meters (30 ft) into the air to overcome obstacles. It can jump on buildings without damaging the components.

   This extreme all-terrain robot is designed for special tasks in surveillance, military and space exploration.

8. ARTHRON R 4075 A – The Flexible Robot (see it in action here)
   This wheeled robot can flex its body to overcome obstacles. Each module has two wheels attached to it. There are in total four modules with eight wheels that drive the robot over obstacles.When there is an obstacle in front of the robot, the first module of the robot rises up to allow other modules to pass over the obstacle.

   The robot is built for inspections in ducts, pipes, cars and anywhere where it can weave in and out.
   

9. Voyager – The Robot for Mars
   Voyager is an adaptable all-terrain vehicle that uses a suspension system called rocker-bogie. This system is designed for the Mars rovers and allows the robots to climb over obstacles that are twice the wheel’s diameter in size.This is an extreme robot for extreme terrain. The adaptable mechanism maintains the balance of the robot even when one of its wheels is on another plane as the other three.
   

Extreme All-Terrain Robots with Tracks

1. LT2 – The Robot Ready to Run! (see it in action here)
   The LT2 is a simple treaded platform designed to handle around 11 Kg (25 lbs) of additional payload in most terrains.
