Building and Controlling the XBot Mobile robots are becoming increasingly common. In factories and hospitals, mobile robots are often used to make deliveries or perform dangerous jobs, and mobile robots are even being used in the home. Figure 1 shows a basic robot with an aluminum chassis and two servo motors. Figure 1. Mobile robot. In this project, you will create your own mobile robot, which we refer to as the XBot. Mobile Robot Unit 1 has three challenges. Challenge 1 is the hardware portion of the project--building the XBot. In Challenge 2, you will program the XBot to execute some basic maneuvers. In Challenge 3, you will write a function to make robot navigation much easier.
