Client: National Robotics Programme Office
A major shortcoming of current floor-cleaning robots is their inability to access staircases. sTetro extends cleaning efficiency by autonomously switching between floor and staircase cleaning modes, so both surfaces can be cleaned without any user intervention. Its body consists of three cuboids connected with two sliders attached to each side of the middle cuboid.
