Robotics is great but if you have a lot of kids that want to take part, you’re going to need a fairly large number of sets.  You don’t want to have spend the first 15 minutes of each class rebuilding the base robot for the lessons of that day. Up until now, you could use the ROBOTC Virtual Worlds, which ... Read More »

I may not be much of an NXT-G programmer but I can spot a good thing when I see it.  Gus over at HiTechnic has been a very busy man. Last time he brought us the really awesome PID motor block but this time he went the extra mile and made no less than three new blocks: A new IR ... Read More »

RS485 on NXT-G? Sure We Can!

Give it up for my main man Andy Milluzzi who, with some help from John Hansen, created the world’s first NXT-G block that leverages the NXT’s RS485 communication abilities! Well done. What does that mean?  Well now you can connect two bricks, back-to-back with a cable connected between their S4 ports and communicate at a blinding 921600 bps!  That’s quite ... Read More »

Rotacaster One-Kit Omniwheel Program Update

I made some updates to the line following program for the Rotacaster One-Kit Omniwheel robot.  This version 2.0 allows you to adjust the Gain and Power variables by turning the back wheels back and forth.  When you’re happy with the values, you can hit one of the bumpers and it’ll start the auto-calibration routine and attempt to follow the course ...

Rotacaster One-Kit Omniwheel

As I was building one of my previous omniwheel frames, I wondered if I could rebuild it using nothing more than the parts that came with an NXT 2.0 Retail kit and three Rotacaster omniwheels.  After a few hours I came up with this: Quite nice and a pretty stiff frame that doesn’t bend much. Please note that not all ... Read More »
