Finally, after months and months of stalling, I have started and completed a tutorial for my Driver Suite. It actually took me a lot less effort than I originally thought it would, but I am happy with the result, as I am sure you will be. The tutorial will help [...]
I don’t usually use graphs but when I do… Ever since I started writing my drivers back at the end of 2008, I would not have thought that I would now be almost at 6000 downloads. I was pouring over the stats and I noticed something quite cool. It is [...]
Dexter Industries seem to really crank ‘em out lately with all the new sensors. This time they’ve made a really nice compass sensor based on the Honeywell HMC5883L 3-axis digital compass IC. I’ve had the pleasure of playing with this little beauty for a little while now. A preliminary [...]
Now here’s a bargain you can’t refuse. The folks over at Robotics Academy have created an RCX-only version of ROBOTC 2.03 and made it available for everyone to download! For free, no less! That’s a lot of exclamation points! Ever since ROBOTC 2.02+ was released without RCX support, a lot [...]
Mindsensors have made a new pressure sensor and it’s really sweet. It uses their new compact sensor housing and it’s very slick and robust looking. Rather than calling it the PPS v3, they gave it the uebercatchy name PPS58-Nx. So what can it do? It can measure pressure from 0 [...]
Titus Woo posted on the ROBOTC forums about a really cool new program he’d written to make it easier for FTC teams to make a teleop program for their robot. I’ve never done FTC but I maintain the ROBOTC forums so I see a lot of question go by during [...]
I received my HiTechnic SuperPro Prototype Sensor in the post yesterday and it’s epic. It’s epic for a number of reasons: It has more inputs and outputs than you can shake a stick at, both analogue and digital. It can 6 digital strobe outputs (great if you want to start [...]
Ivan Seidel from Brazil made a really great video to explain how PID control works. The video is in Portuguese but if you click on the “CC” (closed caption) button at the bottom, you’ll get English subtitles! Go watch it, it’s really awesome.
Dexter Industries have used their WiFi sensor to send a Tweet straight from the NXT over WiFi! It uses the Arduino Tweet Library relaying site to send them which is really, really cool! I am so going to rebuild TwitterTattle to do this. No more tethering needed! This is fantastic. [...]
Dexter Industries have started selling their new Inertial Measurement Unit (IMU) that has both a gyroscope and an accelerometer. Gyroscope The gyro has 3 ranges, 250, 500 and 2000 degrees per second with 1/128, 1/64 and 1/16 degree accuracy respectively. It can measure the rate of turn on all three [...]
