Meet the COWAROBOT R1: a smart robotic suitcase that automatically follows you and keeps proper distance as you walk. It relies on sensors and cameras to sense its environment, plan paths, and avoid obstacles. The suitcase can detect your position and find its way back to you within a certain distance.
You also get an intelligent lock, proximity alarm and embedded GPS. The portable power back can charge your smart gadgets too. You can order yours here.
