Short Range Personal Rad
[attachment=43442]
INTRODUCTION:
The idea to create a type of close proximity radar system came from a student in one of my classes. We went ahead and decided to streamline the idea into the course as one of the projects we'd build. After a week or two of prep time we finally agreed on the project setup & parts that we'd use. This is not meant to be an advanced project, thusly the difficulty is set at medium. Below is an example of what short range personal radar could be used for. It's meant to be a bit comical so feel free to laugh!
Purpose & Overview of this project:
The goal of this project is to create a working ir radar system. The system will only be required to measure close proximity at an angle of 90 degrees as seen in the example above. The range of system is roughly 4-30cm, 20-150cm & 1m-5.5m depending upon which sensor you choose to use.
The outcome of this project will shape future projects where we try to integrate such a radar system to help navigate mobile robots through the real world.
Electrical Parts :
LM7805 5v Voltage Regulator
PIC 18F452 Microcontroller
GP2D120 IR Sensor
4 or 8 MHz Oscillator
SPST Switch
1µF Capacitor
30 pin SIPs
5x 74LS373 Latches
Prototype Board
Solder
36x LEDs
Wire 30 AWG (aka Wirewrap)
Wirewrap Tool
Soldering Iron
Parts List Details:
You may or may not be familiar with the parts above so a picture of each item has been included to help give you an idea of what they look like. Three new objects that we've never seen before appear in this project; Servos, the 74HCT373 & IR Sensors. Tutorials on Servos & IR Sensors should be up soon but for the 74HCT373 I've given a brief overview of it below. You can always check out the datasheet for the chip by search google for "74HCT373".
