NXTway-DS (Double Light Sensors)
NXT GT-Hi with ESC: NXT GT is back with ESC (Electronic Stabiilty Control). NXT GT-Hi has a HiTechnic Acceleration sensor and a HiTechnic Gyro sensor to control traction and oversteer/understeer. This is not the final version yet, however, you can see the effect of ESC.
NXTe/LSC RC servo: LATTEBOX, a Taiwan based robotic platform design house has provided RC servo controller products which are called NXTe (NXT Extension Kit) and LSC (10-Axis Servo Kit). NXTe and LSC enable NXT to control RC servo motors via I2C. nxtOSEK 2.02 sample code (ecrobot\nxte) shows how NXTe/LSC can work by using nxtOSEK in the enhanced NXT standard firmware.
NXTway-GS and NXT Remocon : This is a new video for NXTway-GS(and NXT Remocon). NXT Remocon is a Bluetooth based remote control device which is similar to Nintendo Wiimote. nxtOSEK supports 1:1 NXT communication via Bluetooth. Both nxtOSEK applications are executed from the enhanced NXT standard firmware.
NXTway-GS (Gyro Sensor): There are many NXTway using HiTechnic Gyro Sensor in the web (most famous and the original one is Ryo Watanabe's NXTway-G). nxtOSEK version of NXTway with HiTechinic Gyro Sensor which is called NXTway-GS shows excellent performance (very robust against disturbance, runs and turns on flat floor/slope/rough road controlled by Bluetooth based R/C). Application program of NXTway-GS is designed in Embedded Coder Robot NXT and automatically generated floating point ANSI-C source code with nxtOSEK is implemented into the robot. Detailed informatin about NXTway-GS (e.g. equation of motion, physical dynamics, and building instructions) is available as pdf documents and Simulink model at here.
NXT GT Drifting: Here is the LEGO Mindstorms NXT GT Drifting! You can see the effect of Electronic Differential Control. Additionally,
NXTway-DS (Double Light Sensors): This is Yet Another NXTway powered by nxtOSEK. NXTway DS control algorithm is based on a control theory (state observer + LQ regulator). Control program is activated every 1msec and calculated in fixed-point (not floating point). This high performance and complex C program is not written by hand coding, but Simulink/Real-Time Workshop Embedded Coder automatically generated. NXTway DS C source code is included in the samples of the nxtOSEK distribution.
