PIXI (the NXT cat) Hello everyone, I'm here to present the creation of my son: PIXI ...the Lego cat! Last Christmas after receiving the Mindstorm NXT he has decided to make a robot-cat inspired by our real cat! Here you can see the two cats: Pixi and Felix ...the first one eats only batteries the second one eats everything except batteries! Pixi has some funny details like moving ears, a real tail and a beautiful cat snout with funny expressions... ...but it use also some NXT part to play with humans: 2 Servo Motors, for moving 1 Touch Sensor, to start purring when caressed 1 Sound Sensor, to start when it hears a sound 1 Ultrasonic Sensor, to go away from obstacles With its 4 wheels Pixi can go forward, left, right and backward, if an obstacle is on its way Pixi turns and it goes away from it. After a bit of time, it stops: if you push its back, as if you were caressing a real cat, Pixi starts to purr… and it hasn’t claws to HURT you! After you have caressed it, you can spell any order to it, and it starts. ...enjoy the pictures... - THE END -
