What will you build?

[Mini_Man176]

I thought people might like to share what they're going to build for our pulling competition. This is the place to do it!

I will probably be building something with 4 wheels at the front, a turning mechanism at the back, and a light sensor to navigate the course.

I'm not quite sure exactly how i am going to build it yet, Be it be wheels or tracks, Skid Steer or rack and pinion Steering. All i know it is going to have to be geared down, and have an extreamly strong way of hooking a load up to it.

[Mini_Man176]

Yeah, mine is going to be geared down a lot too. If I was you I would use wheels, becuase tracks don't have that much grip (unless you have the tank tracks).

[snowblader13]

No i was planing on using tires, i was just giving ideas for others, i already know exactly how i am going to build it, but dont know how much it will be able to pull.

[Mini_Man176]

Oh, right. This is turning out to be quite a hard challenge.

I wish I hadn't taken apart my Sumobot 2 (http://nxtmongersworld.blogspot.com/200 ... ot-v2.html) , that was a really good puller. It could pull my stereo on a cart! Still, maybe I can rebuild it.

[Mini_Man176]

Yeah, but for this challenge we can't have wheels under the weight. That will be harder.

Mine's already pulling 3lbs! (I know this isn't very much but it's good for me.)

[snowblader13]

Well i havnt started yet, but we dont know maybe we can only get them to pull about 5 pounds or so. i know from experience that you can lift about 50 pounds. my heavy lifter is proof of that, but pulling is a little bit different, we may have to change it up a bit.

[snowblader13]

Wow this challenge is going to be alot harder than i thought. mine was pulling about 3.8 pounds of weight, but i only had a huge box at the time, so maybe it was that, so i will try again and try on hardwood floor to see if that works better. Also i found the robot needs to be heavy enough to get enough traction to pull the weight.
