In this post I will show you how to measure distance with the EOPD sensor. I will explain the math and give you some data and show you how it was analyzed. Equations for calculating distance as well as calibration constants will be presented. Sample code in LEGO Mindstorms NXT-G and NXC. Read the rest of this entry »

HockeyBot – Trike Based IR Seeker Robot

February 25th, 2010

This HiTechnic Trike based project uses the HiTechnic IR Seeker V2 together with the IR Ball to make a Hockey Bot. (Or call it a Soccer bot if you prefer, but as I write this we are in the middle of the 2010 Winter Olympics so I have Hockey on my mind).
