X-Terrestrial Rover
Hello, NXTloggers. This is my first ever robot to ever go on NXTlog. Anyway, let's get started. This is a all-planetary rover (except gaseous planets), that collects its data using the mechanical arm attached to its back. The arm has the ability to rotate a bit over 360 degrees, to offer the best collecting experience. As for the rover's drive system, it contains no gears. The fact that the car is too heavy for gears to handle, I had to make a direct connection to the wheels. Some of you may be wondering: where did I get the wheels? Well, my wheels came with the 8297 Off-Roader set, but I'm pretty sure you can buy them separately. The Ultrasonic sensor makes sure that it doesn't smash into a vertical surface. The light sensor compares the brightness of the surrounding space. If it is too dark, it will turn on the color lamp. Next comes the HiTechnic color sensor (V2). It measures the color of the space it is in, and then turns the color lamp a different color, according to the best lighting for each texture color. The last sensor is inside the hull. The HiTechnic accelerometer sensor. If the rover is tilted over 50 degrees, it automatically puts its motors into reverse,To make sure it doesn't fall on its back. Otherwise, the arm would be ruined. If this model were real, I'd say it would be heat resistant, acid proof, have a highly advanced camera, that would calcuate the state of the object (gas, liquid, or hard), and the material. Of course, it can't grab liquid or gas, but it can still calculate without grabbing, for it is a camera, and final thing, the ultrasonic sensor would be replaced by a live footage, high-definition camera. Now back to the Lego rover. I will not post ldd or program, for the ldd would take forever because of my lack of experience with ldd, and the program is available to all NXT 2.0 users. Stay updated because I will publish a video between September 9th to 15th. Hope this caught your interest. I'm all ears to suggestions for add-ons, but it is impossible until the end of the Explorer Bot challenge. Until then, happy summer!!!

A Change to the Rover

Sorry for the mistake in my previous description. I do not have a Lego Multiplexer, so I can't connect 5 sensors. I'm removing the Color Lamp, and replacing it with the Power Functions headlights. The Color Sensor V2 will be used to detect the color of its surface, and the light sensor will light the color sensor's way. I know, not much has changed in the picture, but the accelerometer sensor has been moved from the inside to the top.

The Video

Well, here is the moment you've all been waiting for. The Movie. I hope you all enjoy it, because I worked hard on it, especially with the editing. By the way, there are a variety of different sensors to put on. If I had a multiplexer, I would have included all I have. Enjoy the show!

The Newcomer

Hello, Lego fans. The Next Generation model of the X-Terrestrial Rover is finally here! It is smaller, lighter, and easy to control. Like the first rover, it is remote controlled. It was inspired by the compact Smart Car. Get a look or two when it lands.

  • My only suggestion is to stablize the wheel hubs

  • Cool project. The only thing I can think of to improve it is to make the back part flat, so you could put objects on it.

  • LegokingMindstormsGenius: I was thinking of the same thing, except there was too much electronics inside, like the nxt, and I didn't want to make it look all big and bulky, unlike the round roof you can see on pic. #4.
