Summary

In this chapter, we designed and built an autonomous mobile robot from scratch. The design of the robot started with its specification. From the specification, we designed various parameters of the robot, such as motor torque and speed. After finding out each parameter, we modeled the robot chassis and simulated it using ROS and Gazebo. After simulation, we saw how to create the actual hardware. We selected the components and interconnected the sensors and actuators to the embedded board. We wrote the firmware of the embedded board. The board can communicate with the PC on which the ROS is running. The ROS driver node receives the data from the robot and interfaces with the gmapping and AMCL packages to perform autonomous navigation.

In the next chapter, we will see how to create a self-driving car and interface to Robot Operating System.
