Implementation

To realise this concept, we created an environment to represent the idea of sorting products. We provided 4 parking pads, each labeled as "0", "1", "2" and "P". The robot is designed to always start from parking pad "P" and also return to it. When located on the parking pad "P", the robot awaits instructions. We modelled the instructions given through the IR remote. After the robot received the instructions, it will automatically relocate to the designated parking pad (numbers "0" through "2"). A 1 second buffer is presented while on the parking pad to symbolise waiting time for the to-be-sorted product to be unloaded. Afterwards, the robot should return to the original starting point (parking pad "P"). Meanwhile, we using the on-board LED as signals representing different phase of motion (as shown below).
