ROBOT BY: PRAMA NAND
Hello !!
Robot competition TAFE NSW 2010
This is a website designed to illustrate and outline the construction of the robot called AMARP ROBOT to compete at mount druitt tafe. Project started with the base and the design of using tracks BUTafter a bit of thought I changed conventional wheels and a front castor to make it faster and more presentable
Sensing
Originaly I was going to use infrared but then dicided on using ULTERSONIC for better range and less chance of outside interference. The sensor were bought from dicksmith . These were changed to picaxe items which had a much greater sensing range for same current (amps) value.
Programming
. The choice was made to change the program to follow the wall so it tried to keep in sight with the wall this works much better as it doesnt matter how straight it is.
A lot of time was spent fine tuning and if there was voltage interference the program wouldn't work properly. this was making it hard to control to keep in a straight line and once of course would need help. and J.K the class teacher was to safe us all the time. Originaly I was going to use infrared but then dicided on using modulated IR for better range and less chance of outside interference. The sensor were bought from dicksmith but there range was poor and the minimum voltage valve was 4.2V making them a poor choice and difficult to work with. These were chnaged to farnell items which had a much greater sensing range for same current (amps) value. The farnell sensors also worked well below 4v.
