The Aim of this project was to design and build a proximity detection and range-finding system, for distances up to about 2 metres, for the 'Mini-Mobot' mobile robot (now calledBIRo's).
The theory of Ultrasonics, and range-finding by ultrasonics was investigated, and a basic system outline was designed. This was then refined to try to protect against the ultrasonics on one robot interfering with those on another, and adapted to include some inter-robot ultrasonic communications capability, whilst keeping the increase in circuitry to a minimum.
The full circuit was then designed and built in sections, as a prototype, and any problems solved, before a PCB was laid out, and the final circuit built. This circuit was then tested and although one unexpected result arose, the circuit worked successfully and better than had been hoped as a range-finder, detecting small objects well. It worked about as well as expected as a simple communications system.
Abstract - Same as above
Executive Summary - Complete except for 2 figures that were 'scope screen photos.
Main board of report - Sorry, not yet available as the wordperfect file is corrupted. (this is not news - it got corrupted 2 days before the due date for the report, back in '92, but I managed to print most of it at the time)
Circuit Diagrams
Appendices Including layout of boards - Not complete; I'll add the PCB artworks / assembly drawings when I find them
(Note - The document was originally written in Wordperfect 5.1. I recently sucked the file into Word 97 then PDF'ed it. In the process some of the graphics were trashed by Word, and I haven't got around to fixing them.
