Precision Court Sweeper

Sammanfattning: Tennis is a popular sport and in summer it’s often played outside. When an outdoors tennis court has been used it needs to be brushed. First the whole court is brushed witha large brush and then the white lines with a smaller brush. The aim of this thesis was to design and build a working prototype of a robot who can do all of this by itself i.e sweep the court and then the white lines. The budget for components to the prototype was limited to 1 000 SEK. Tools and other resources such as 3D-printers, soldering equipment and laser cutters was provided by KTH for free. First information and inspiration about self-driving cars and driving patterns was collected and some important sources were old bachelor’s thesis. Then, needed components and dimensions could be determined. In this project the main components were an Arduino Uno, two DC motors, an L298H-bridge, an ultra sonic distance sensor, an on/off switch, AAA batteries and a 9 V battery. The conclusions that could been drawn was that the robot can work good enough to sweep a court with only a preprogrammed path. However, to sweep the white lines, sensors would be necessary. It could also be concluded that a robot could sweep the court at the same speed as two people could do it.
