Interactive Ultrasonic Guided System
1. Overall design and preliminary research
1.1 Introduction
The idea for this project came from my supervisor, Phil Tranter. From a list of possible topics
I chose the three most interesting for me.
The aim of the project is to develop an ultrasonic guided system, applied in a mobile robot in
order to avoid objects. Furthermore the project will provide a total remote control for the
robot, via a radio communication system of 434 MHz1.
All the systems must be included in a single PCB2 that fits in the robot bodywork. In addition
to this a remote control must be constructed.
1.2 Evolution of the project
The development of the project has had three main structural changes. At the beginning the
project consisted of the creation of the motion system for the platform, the design of the
ultrasonic avoidance object system and the implementation of the wireless remote control.
At the end of November my supervisor offered me a complete robot system called RP63
which improved my project possibilities because it has an integrated motion system that I can
use instead of designing my own system. The robot system also includes an I2C4 interface,
which was another topic of the proposal projects. The characteristics of the robot system are
explained in the Chapter 2. At this point the decision was taken to pursue a new direction of
the project and to start focusing more on software rather than hardware.
