Meet Tipron: a home robot that transforms to project an 80″ screen from a distance of 3 meters. It can project at different heights and angles. The robot adjusts its height depending on its mode. For instance, it extends 80 cm when projecting but stays compact while moving.
This HD projector offers auto focus and HDMI input. It has a 5800 mAh battery and offers Android support. The robot uses an IR distance camera, obstacle sensor, and video/still camera to serve you. More info is available here.
