Hands-On ROS for Robotics Programming

Robot kit and resources

At a high level, we can group the hardware of the robot into two sets:

• Electromechanics: This refers to the sensors and actuators that allow it to interact with the physical world.

• Embedded hardware: The electronic boards that allows it to acquire a signal from the sensors, convert it into a digital signal, and provide the processing logic and send commands to the actuators. Here, we typically have two types of electronic boards:
  • The controller, which serves as the physical interface with the sensors and actuators—that is, the GoPiGo3 board. The controller deals with both analog and digital signals from the electromechanical devices, transforming them into digital signals that can be processed by a CPU.
  • The computer ...
