Timing Grey
En självbalanserande robot med ultraljud och egenutvecklad hastighetsmätare
This bachelor thesis describes the process of developing a two wheeled robot with activebalancing. The robot is designed to go straight ahead until it reaches a finish line. Then it shallstop to stand still balancing. The workload in the group has been divided according to theprevious individual projects, which are attached. The design of the robot is inspired by theconcept of the Segway. The main components are a DC-motor for the propulsion, an ultrasonicsensor for distance measurements, a reflex sensor which detects the finish line and one thatworks as an encoder. The communication between the remote controller and the robot uses aBluetooth module.The project resulted in a prototype that was able to balance actively using the data from theultrasonic sensor, parry external forces, communicate with a controller through Bluetooth,identify the finish line and run in the desired direction.Difficulties that have occurred during the development process have been solved by creativesolutions and innovative approaches. The majority of the time has been spent on building andperfecting the self-constructed encoder. The importance of being thorough when working withelectronics and testing has been a lesson learned.
