YOU GUYS SEE RESEARCH ROBOT I SEE BATTLE BOT

[Sierrasv]

It's big but I don't see it weighing 400lbs.

[Pieman6711]

For a 400 lb. robot, Molly can really go.

[stopmotionentertain]

makes a high pitched sound

[sugoi49]

This is cool and all, but it is not a robot; it is an R/C vehicle.

[roofy2k]

@sugoi49 it's a robot controlled with an R/C controller

[Pr0F1X]

The PWM frequency of motors should be changed

[jethromayham]

How does it work on different types of terrain?

What is its intentions for it?

[RebelForce8]

Can you sit on it and then drive ?

[allen2688]

i bet thay have a ramp for there car

[joralecru]

what kind of batteries did you use for your prototype and How many amperes does the robot Spend? Thanks for your answer

[ranausman143]

Why 400 pounds? :/

I liked the differential drive

[Doclockword]

400 lbs?? maybe if it was made of a solid chunk of steel. Are you sure it weighs that much?

[drbroccoli1]

Is motor speed controlled with PWM? Is that the noise that it makes?

[PaScAvAgE11]

i bet its not 400 lbs

[spartonne]

wtf that thing is massive! lol. How did you get it back? With a pickup truck or something?

We pried off the offending track with a high-precision crow bar, dragged her off the hill, and pushed her back into the van. This was the third time we've had to haul a non-functioning robot home after a test. Thankfully this time she was up and running again within the hour.

"oh great spectators,

well its ok, as long they don't freak out and call the cops"

"its gonna be great and someone came down here and say: what could possible made those tracks?" haha, you guys are awesome :-)

It's a really great(and expensive!) project. I've read documentation on you're site and I'm really impressed.

[mrspooon]

really cool, where did you get your tracks from?

[yxcwert]

COOL toy- I want it for my birthday

[NotAfraidOfYou420]

Now I'm not saying that isn't bad ass, but isn't it really just a super tough remote controlled car?

[ishizuki23]

No, sir, it's just a super BIG remote controlled car. As you can see from the video, it isn't all that tough.

The original iteration was completely computer controlled, but the wireless was a little unreliable for my liking. I swapped out the fancy computerized inards for an trusty radio and haven't looked back.

[theskilledhunter]

You sir, have inspired me.

[xsyar]

why so slow? isn't the etek motor 5hp?

[revoskid32]

Most likely because of it weight.

[safielaran]

Also, because of the current gear ratio. We've got another set of gears as well.

[ishizuki23]

15hp actually, and there are 2 of them. Of course, that's only at 48V. During this taping we were running at 24V and 11:60 reduction. Max speed is 4mph, but it can climb stairs with an extra 400 pounds on board without breaking a sweat.

ooh! i saw this online! it uses Eteks for drive
