off road vex

i just did a test i made some simaler mettle parts and thay bent at 27lbs and the motors wont pull more then 8lbs with the lowest gear so i just woud not put any xs waght

i was pushing and ur chassis must be weak plus i don’t put all the weight in the same place it is scattered out through out the robot. wat surface did u do it on i did mine on a wood floor.

You know when i was in middle school we had a shop class. I loved it but my teacher Mr. Kelly gosh thats been about 14 years ago and i still rememebr his name. anyway. We had a course in Structures. I think that has to be the pin point ot my builds. One of our class room assignments was we were given 1 sheet of paper. standard printer paper. 20lb 8.5 x 11 inch. and 1ml of glue. ie an eyedropper drop. basically useless you could disolve it in your hand and not notice it. There was all sorts of different designs some round some flat. but we had a height requirement to meet that was 3 inches. this was an indivual project and it was interresting. no i wasn’t the best one there was i got a B for that assignment i only supported 25 pounds before my paper had structural failure. we were graded on the guy who was super dude and his supported his own weight. over a hundred pounds. his idea was so simple. he took the paper cut 3 3inch strips and rolled them up and glued the seam took the remaining paper and made ring around them. so bloody simple yet so strong.

But stone may have pushed the limits of his vex with the 100 pound push with 40 pound bot. it’s possible all it takes is an artiects favorite shape. the triangle. There is alot of weakness with vex but i’m sure that given the time and the thought behind the design vex could have supported it.

There is another thing Mr. Kelly tought us. how to build model rockets from scratch and how to build half a bridge and make it stable. so with that said.

Stone i wish you had a pic. and I beleave that you did it even as impossible as it sounds.

Everybody here could be wrong it just seems like overkill with vex. The way I see it is that it would take so long to move because of the gearing and it would take so much battery power that the robot has no real use. When would you use this? if you could get it to move faster than:confused: I think you said a foot in ten minutes then it might be okay but I still dont understand why you built such a robot.

i built the robot because i wanted to take vex to the limit and see how amazing this technology is. Also i put myself to the challenge to push as much weight as possible just for fun.

Ok that makes some sense to see just how far the kit could go but if you were successful did you add even more dead weight and weight to the robot?

yes i did but than the cluches were starting to striping

Is there a way to make the clutch stronger?

i don’t thinks so but there has been many threads on here about that i think vex labs should really take that into consideration it would be one of there top sellers for sure.

yea there should be different clutches for different uses such as light and heavy duty, and how about some bigger motors? Stone do you have any pictures of your robot?

which one do u want a picture of??

The robot tat you used to push the weight. I would like to see the frame structure.

i don’t have the robot any more and i don’t have any pictures but it was basically a square bot with structural supports on it

too bad I wanted too see it. Do you remember the chassis dimnsions?

it was a square bot from like the manual with custom enhancements to be exact 8 * 8

ok Its hard to believe you got 40lbs. on the robot itself

i did thou it was flat on the top so i just kept stacking weights.

If you make the clutches too much stronger you can damage the motor. I’m guessing that VEX labs just made them the right strength to slip before there’s damage to the motor.

very good point i guess none of us ever thought of that.

Thank you, it’s more or less the reason clutches exist anyways.
