This robot can paint lines on a soccer pitch using Nissan ProPilot technology, GPS tracking system, and four cameras. Lines can be painted on grass, tarmac, or gravel and are environmentally friendly, meaning they will fade away over time.
47. Mini Cheetah
> Year: 2019
> Made by: MIT
Developed at MIT, the quadruped robot can traverse terrain without having to map it in advance. The control system is split into two — one that processes real-time input from a video camera attached to the front of the robot and another system that translates the data into instructions for how the robot should move its body.
