| Abstract | Humans have increasingly sort help from robots to do mundane things like cleaning. This not only saves time for us but tasks like cleaning, in most cases, is done better by robots because they do not tire or get bored. This report describes one such cleaning device that helps to wipe a whiteboard used in classrooms. The robot makes use of a suction mechanism that creates negative pressure and thrust to help the robot stick onto the board. The suction motor comprises of a brushless dc motor and an electric ducted fan. The fan rotates at very high speed typically around 38000 RPM. The adhesion mechanism is that of a sliding suction concept. This allows the robot’s suction mechanism to be at least one inch above the surface. This allows for better mobility in various surfaces and faster movement. The robot uses an onboard accelerometer that gives the position of the robot. It also uses quadrature encoders to measure the length of the board and navigate accordingly. The edges are detected using limit switches. The cleaning of the robot is done using white board erasers that are attached to the underside of the robot. The robot can successfully wipe clean any whiteboard that has an edge of over 2mm in height. The PID control algorithm used is also effective and helps the robot move in a straight line successfully. This design implements a low pass filter to filter out high frequency noises for better accelerometer noises. The final result is that the robot can autonomously clean about 60% of the area of a white board. |
