Robot Climbs Grand Canyon on AA Batteries

5oz = 0.142kg

1740ft = 530m

So the potential energy gained by climbing is 0.142kg x 530m x 9.81ms^-2 = 738J

Over 24360 sec comes out at 0.03W

And at 3V that gives 10mA

For 6³/₄h gives 67.5mAh.

Average rechargeable AAs are around 1100mAh capacity.

So quite a lot more than 0.03W has been expended on calculation and positioning of the limbs, which is why rotating devices driving hoists and winches are so commonplace.

You cracked me up mate!

I think I should pay you one day a surprise visit to see if your kettle's on and see how much J it has spent by the time I get there.

cheers,

Hey we don't even get to see the little fella climbing!

Did he get a tea break after 3 hours?

Del

There's no tea break for robots! They have work straight through their shits.

Sorry guys, I need to apologise for my previous spelling error in the last word and a missing conjunction, I cannot correct it you know.

I guess I was too much in a hurry to check my own writing and I did not notice it until now.
