PDF | This paper presents a case study in combining Lego Mindstorms™ NXT with Matlab/Simulink to help students in an undergraduate Machine Learning course study genetic algorithm design and testing. For example, if the NXT is is programmed to send a bluetooth message ("TEST", for instance) to slave port 1 at the press of a touch sensor, and the EV3 is programmed to rotate motors B&C for example, when the touch sensor is pressed on the NXT, will the message (TEST) come in from master port one (The NXT), and will the EV3 react and rotate. I have read some articles about UART, but I don't know if UART considers the EV3 brick as a device. And voila! So using ideas from bouncing ball I wrote this EV3 app. This allows us to measure distance rather than time. RoboRealm helped to identify the written text on the whiteboard so the robot could be as efficient as possible in erasing text. You can use the resetRotationAngle function to reset this value to zero. To know the rate of rotation one has to subtract the offset from the value the gyro returns. Design a Line Maze Solving Robot Teaching a Robot to Solve a Line Maze By Richard T. Site created by Enktesis. rotation = readRotation(mymotor) reads the total amount of rotation since the creation of the connection to the motor, and returns the measurement in degrees.
