Inspired by BMW's Z4 GT3, I created my own race car with some cool features. My Lego BMW Z4 GT3 contains a four-speed gearbox, inspired by Sheepo. It also has rear wheel drive, suspension, and steering. In order to make all these functions work, I used an NXT for operating the transmission, two NXT motors for switching gears, and two NXT touch sensors for operating the motors. The drive uses two PF XL motors, and the steering uses one M motor. Another M motor and E motor are used for bumping the NXT touch sensors to switch gears. Enjoy!

Mobile Crane is a crane that is mounted onto a trailer.
This crane shares alot of similarities with Remote Control Crane It has the same engine program exept it uses the color sensor to turn the engine on and off, a green ball turns it on, and a red ball turns it off. It can turn 360 degrees and has stabilizer jacks.
Motors turn the turn table, lift the boom, raise and lower the gripper and, open and close the gripper. The boom and gripper are raised and lowered with string.How it works:
It makes an engine noise by using the color sensor. It uses two touch sensors and the orange NXT button to turn the crane and raise and lower the boom. If the ornage NXT button is pressed it reverses the direction that the motors turn.
Thanks to the suggestion from TheSuperHedgehog1753, I remade the bot with some tracks and was able to take it out in the nice weather and field test it. I uploaded a video showing it in action. I had to move the wall following sensor higher because the grass blades kept setting it off. Please ignore the single gray track piece (I ran out).
The RCX robot of my Sumobot competition is Ramps, a short but powerful robot, that can push opponents out of the rink, or mislead their sensors by driving under them. One of Ramps' greatest strengths is that it is almost completely undetectable to opponent distance sensors, and, due to Ramps being so low to the ground, most distance sensors look right over Ramps. Even when opponent's sensors are low enough to be on Ramps' level, the angled nature of Ramps' ramps deflect ultrasonic noise, so opponents can only see Ramps from the side. Upon a suggestion from my brother, I added an interchangeable set of white plates, so that opponents will not be able to detect Ramps, even with a color sensor. I will now go into detail on Ramps' individual parts.
I now present a new challenge, the PLAN3 Challenge! (Mostly to fill in my inactivity here for the time being…) For this challenge, build a robotic airplane with RCX, NXT, or EV3! It doesn't have to fly, don't worry! Rules are in Additional Information. Have fun! Must add the tag: "PLAN3". Deadline: April 1, 2014.
