Robot arm controller

This is an app for controlling a robot arm with a dashboard, specifically its angle and the parameters of its PID controller.

The robot runs in a separate process and it receives and send messages via a channel. The dashboard communicates with the robot via the channel, pushing new parameter updates and periodically retrieving the state of the robot.

This app showcases:

• Communication between separate entities via channels.
• Using asynchronous tasks for running long processes.
• High-frequency plot updates in real time.
