I can use this project and experiment on it to expand my knowledge. I want to try using the PID line tracing method for two light sensors. I have learned that the more sensors one has, the more precise their line following becomes. PID is very precise already, so having two sensors would be great. In this project, I wanted to grab objects and move them, but the object were either too short for the sonar to detect or too wide for the claw to grab. If I were to use a physical robot I would have the ability to move sensors around and make adjustments to the claw. This is why I would like to use a physical robot on my own time.
