Thanks to the hard work of Gus Jansson of HiTechnic, you can now do sin, cos and atan2, all from the comfort of your NXT-G programming environment! How cool is that? Just go to this page and scroll to the bottom. There are integer versions for NXT-G 1.0 and floating point ones for NXT-G 2.0. They’re proper NXT-G blocks and really fast, much faster than any MyBlock versions that have been cobbled together before.
I was able to test these blocks a few days ago and they work wonderfully with the Rotacaster omniwheels! I’ve been working on some example programs for the One Kit Omniwheel and I’ll post some over the next few days so you can get an idea of how to use them.
