Hinged Tetro Vacuum Cleaner Robot

Designer: Lecturer Mohan Rajesh Elara

“Current day vacuum cleaning robots are often highly constrained by the artefacts they interact with within their operating environment and that greatly affect their cleaning performance. Our objective with Hinged Tetro is to achieve self-reconfiguration with respect to interacting artefacts in order to achieve optimal cleaning performance while being able to autonomously shift between available states. The shaping shifting character of this robot enables it to efficiently clean room corners and narrow furniture spaces beyond the reach of existing cleaning robots.

We were inspired by Tetromineos, made popular in the video game Tetris. Our Hinged-Tetro is able to transform itself into any of the seven one-sided Tetrominoes which enables it to adapt to a broad range of cleaning environments. Hinged-Tetro’s body consists of four cubes connected by three revolute joints. Each cube has a hollow space which encloses the vacuum suction unit. The modular design allows the re-use of parts within the system.”
