2 Overview
MaeGo is the world’s first AI robot car that runs, stops, turns and
performs preset tasks autonomously to play FPS games with you in
reality.
You can shoot infrared rays using the IR blaster or foam balls/darts
from Nerf blasters at them in a multiplayer battle, having fun for hours
with your families and friends.
MaeGo is more than an AI robot for shooting games, but also a
coding platform to cultivate children's logic and strategic thinking and
prepare them for school and future careers in STEM.
