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 »
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). This robot uses the IR Seeker to locate the IR Ball and drive towards it. When the Ultrasonic sensor detects the ball right in front of it, then it gives it a good slap shot (or kick if like soccer).

Here is an NXC version of the HiTechnic WallBot. This program is essentially the same as the NXT-G program from the previous post except it does add one small improvement. This version displays on the NXT screen information such as the raw EOPD value, the processed steering value, and the power that is being used for the two motors. Read the rest of this entry »
The WallBot is wall follower that uses a HiTechnic EOPD sensor to track the wall on the right side of the robot and an Ultrasonic Sensor to detect inside corners. The robot is based on the new HiTechnic Trike Base. In this article the program is in the LEGO Mindstorms NXT-G programming language. Future articles will demonstrate the WallBot in other languages too. Read the rest of this entry »
The HiTechnic Blog is all about HiTechnic sensors and our other products. We will show you how you can build cool models and explain how to program them. There will building tips and programming tips. We will talk about sensor data analysis so you can understand what the robot ’sees’ and figure out how it can respond.
There will also posts with links to articles about other projects out there that use HiTechnic sensors or multiplexers. Read the rest of this entry »
