Often the process of handshaking goes beyond a robot’s need to communicate with another robot. In industry the process of have Programmable Logic Controllers (PLCs) communicate with each other, or robotic arms can be just as simple as having two robots communicate. It is a very simple form of communication and is done with simple ones and zeros; or “ons” and “offs”.
In this activity we will reuse the theory of communicating with simple ones and zeros; or “ons” and “offs” from the previous activity. We will replace the robots with two micro-controllers. For this activity, we will focus on the wiring and syntax programming for two Arduino micro-controllers. Robotic arms need to communicate with other robots in a work cell, or factory. This is called HANDSHAKING and can be done between different machines, devices and robots. It is a very simple form of communication and is done with simple ones and zeros; or “ons” and “offs”.
The limit switch attached to each microcontroller will control the on and off function of the other controller’s motor.
