Automated Tile Polishing Robot

Abstract

Under the present scenario tile polishing is a tedious, expensive and time consuming process with a high dependency on efficiency of human workers. This work involves the design and fabrication of an autonomous robot for polishing of tiles, granite, marble and other floorings. In this device, electricity stored in a battery is used to drive two motors for vehicle movement and one motor for the polishing disk. The polishing disk holds the abrasive material use to grind and polish the tiles. The disk also has provisions for holding and easily replacing the abrasives depending on the type of flooring. The Arduino microcontroller controls the motion of the robot which is aided by the use proximity Ultrasonic sensors. A universal joint connected to the shaft driving the polishing disk keeps the disk in constant contact with the surface. The vibration sensor attached to the device determines the duration of polishing. The device if implemented on a larger scale can be a boon to the construction industry and also for domestic use for floor polishing in households.
