HULC an NXT Crane Profile



That's really nice! :D About how much can it lift?

@ SprinkleOtter Thanks! Good question, I only tested it with two of my Lego boats. The boat in the video, which weighs about 1/2 lb, and an old police boat that weighs 1 lb. It lifted the 1/2 lb ship no problem. But it just barely got the 1 lb boat off the ground and really stressed the technic beams and worm gear. I didn't try anything heavier. So I would say it can lift up to 1 lb approximately.

very cool

Very good dessing.

@ jedicaleb7 Thanks!

Always Awesome Job AREM. Very beautiful Design :)

@ ecarvajal Thanks! I am assuming you meant 'design'? @ Kwon8429 Thanks!

I like the concept and design! I would suggest though, hiding the ultrasonic sensor in the cockpit, or even substituting it for headlights.

@ streamliners Thanks! I was originally going to do that but I decided to change it so the U.S. sensor could turn side to side. It was one of those functionality vs. appearance choices and I decided in favor of functionality. Thanks for the suggestion though!


Sorry you got a 3* on this project. I can tell you put a lot of effort into it :( I kinda know what it is like to get a project rated like this. I worked on my UB biped for over 2 months but it still got only a 4 star rating (NXTLog 4* not the new rating system). Some people do not know how to rate projects.

@ barriebently Thanks! @ DaveAndJoe I noticed the three star rating and thought it was a little low. (Its up to a four now, thanks!) I though your UB biped was awesome but I don't remember if I rated it. I will go and rate it now!

Awesome! I wonder how to design a great robot like this. Neat and tidy!

What actual pieces did you for the hook? I'm doing a similar model but having trouble with the hook. Sorry, it's a little hard to tell by just the picture.

Never mind. I figured it out close enough. I really liked your design. I will probably upload my forklift/crane in a few days.


You should make an Ev3 version!

@ juandaeli01 Thanks! Just keep working at it and you will eventually be able to make great robots! @ douglasjaymiller Sorry I didn't respond sooner but I am glad you figured it out! I can't wait to see your forklift/crane! @belac853 Thanks!

@ BrennanRocksBB I am sorry but I am not building a tank right now, so probably not. It sounds like a fun contest but my current project would not really qualify.

Hi everyone, AREM2326 here with my latest project H.U.L.C. Huge Ultimate Lifting Contraption. It uses 1 NXT 2.0 brick, 3 NXT servos, 2 NXT touch sensors, 1 NXT color sensor, 1 NXT U.S. sensor, 1 RCX motor, 1 XL PF motor, 1 M PF motor, 1 PF switch, 1 PF IR receiver, 1 PF battery box, and 1 set of PF lights. It features four wheel steering linked to the ultrasonic sensor for advanced object avoidance, the crane moves up, down, left, right, and features working winch. All this and more will be described in the next steps so keep reading!
