DESIGN NAME: sTetro
PRIMARY FUNCTION: Autonomous Staircase Cleaning
INSPIRATION: Most urban cities are witnessing a rapidly accelerating pace of life and shrinking personal, family and community time. sTetro is set to significantly improve productivity in handling cleaning chores while saving valuable time for social activities with family and community.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Even though there exists numerous precedence demonstrating the benefits of floor cleaning robots, one major factor attributing to their performance loss is their inability to access staircases. sTetro is capable of both floor and staircase cleaning modes, thereby, significantly maximizing task performance. Our sTetro is able to autonomously map its environment using on-board sensors and navigate on both flat terrains and staircases to clean the environment efficiently.
OPERATION / FLOW / INTERACTION: sTetro app supports WiFi connectivity allowing users to operate from anywhere, anytime. In manual control, the users can choose from a list of robot behaviors such as forward, backward, left and right and deployment modes such as floor, staircase, and hybrid. Once set to autonomous mode, sTetro navigates around the deployed space maximizing area coverage and cleaning performance while switching between floor and staircase cleaning modalities all by itself. The onboard touch panel displays the operating mode, remaining battery capacity, and error codes under abnormal conditions.
PROJECT DURATION AND LOCATION: This project started in August 2017 and supported by the National Robotics R&D Programme Office.
FITS BEST INTO CATEGORY: Product Engineering and Technical Design

PRODUCTION / REALIZATION TECHNOLOGY: sTetro's body consists of three cuboids connected with two sliders attached to each side of the middle cuboid. Each cuboid encloses the electronics, vacuum suction, and sweeping units. The blocks have a modular design, allowing for an affordable price and easy to replace components. A smart application allows the user to control the robot to start and stop, navigate to follow a defined trajectory and change operational settings. The reconfiguring mechanisms allow the robot to efficiently clean both flat floor and staircases at one go without any user intervention that is almost impossible for current day cleaning robots.

RESEARCH ABSTRACT: Considering the crucial role staircases play and their permanent presence even after the advent of lifts and escalators in multi-story buildings, the subject of cleaning staircases has received little attention from roboticists. What we want to achieve is to be able to extend the cleaning efficiency of these robots than it is currently feasible. Particularly, we are developing a new class of cleaning robots that can handle both floor and staircase cleaning modes by maximizing task performance.
CHALLENGE: The main challenges in designing our sTetro robot include the design of a highly versatile mechanism, optimal use of materials while not compromising the stability and the nontrivial process of implementing theoretical designs generated analytically into physical mechanisms.
