Hamster bot

The Rosphere, developed by a team at the Universidad Politécnica de Madrid, looks and functions just like a hamster ball, rolling over your croplands without the use of wheels or legs. Inside the Rosphere, a pendulum rotates on an axle to make it roll and steer itself, like a hamster running up the sides of a ball. It’s perfect for navigating crops without harming them, and rolling over uneven terrain. Using GPS and wi-fi technology, the device aims to collect information about soil composition, temperature, moisture and plant health, then broadcast it back to the farmer. And if the autonomous little robot somehow gets trapped, you can take over the controls and steer it remotely.
