Building Low Cost Autonomous Robots

Director, NEX Robotics
In this chapter we are going to write important functions for the robot like LCD display, velocity and direction control, acquiring analog data etc. In the first step we are going to do LCD interfacing. If you don’t want to use LCD then you can skip this step and go to I/O interfacing section. LCD interfacing: At first it looks not so important but it will be very useful when you are going to calibrate your line sensors. It will be very useful when you deploy your robot in the contest arena and your sensors can display amount of ambient light interfering with your sensors. It can also show on what node your robot is and where it is heading. If you display node number (column and row number of the white line) you can very easily identify problem if robot is missing the nodes. At first LCD interfacing seems bit complicated but it is very easy if you use standardized code. You don’t have to reinvent the wheel. You can use LCD display code from our projects as open source content.
