Abstract
The primary motivation for this project is driven by the theme of National Instruments Autonomous Robotics Competition (NIARC) 2020, which is to study the properties of
particles physics when accelerated by electromagnetic field and collide with each other. The main goal of this undergraduate project is to design and program hardware to collide specific particles for research, both autonomously and manually, using the principle of a particle accelerator and collider. As an improvisation from the task distributed in the competition, the project is completely designed in an autonomous manner. In order to realize this goal, a robotic prototype is constructed using MyRio Field Programmable Gate Array (FPGA) and LabVIEW software together with intelligent robotics algorithms such as autonomous navigation and colour detection using Logitech C922 Pro HD Stream webcam. Once the particles represented by the ping pong balls is tracked by the robot, a pick and place mechanism works in a way to collect and place the detected ping pong balls into the shooting mechanism. The ping pong balls are then targeted towards a hole, and launched using two high speed DC motors which are attached to the sides of L-joint polyvinyl chloride (PVC) pipe. The high speed DC motors connected to the rubber wheels inside the PVC joint rotate to launch the ping pong balls, creating a shooting mechanism. The quantitative result for this project is based on the angle of depression of the webcam to detect the position of the ping pong balls, the cellular voltage supplied for maximum number of ping pong balls to be launched into the target hole, and the number of balls collected when the collecting mechanism is operated with direct and gradual servo angle manipulation. The impact of this project is the succession of the particle accelerator and collider principles, specifically when the collected ping pong balls are accurately launched
through the target holes of the game field.
