Let's Make Robots! | RobotShop

Green Machine (!!!!!)

Basically, this is a long term project for geniuses, you have to make a FULLY ELECTRIC HUMAN TRANSPORT VEHICLE. Extra points for aerodynamics and using a better resource than a wall outlet, like a solar panel or a little windmill that uses the wind as you drive. 

It could be a boat, a car, a bike (windshield wiper motor on a bike, hint hint, been meaning to do this) a segway thingy, anything you think of. And yes, even a walking chair!!! yeah!!!

RULES:  yes, they can be confusing, i know :D



(And yes, it has to be safe! If it doesn't travel too fast, great, but if it is too zippy, you need seat belts.)

 remember: extra points if the vehicle does not need to recharge from a wall socket!!! and also extra extra points if you paint it green! hehe, almost forgot 

As for the reward, I don't know. I have limited resources and i cannot ship, so unless someone else is willing enough to pitch in a prize, I guess it will be mine and LMR's respect!  not too shabby though :)

lol, and the challenge now has a due date at the "end of the world"

wow. thats why its called a challenge. i suspect not many people will do it, because its going to be very expensive and what will you do with it after cos i dont think you will be able to make it street legal. hey go for it if you think your up for it.
yeah, i understand, but for people with the know-how and all that, this should be a cool project
I am IN !  I want to build a 3 wheeled solar powered car. It will basically be a solar powered bike, You can buy electric bikes now at Toys-R-Us for $300. So all you have to do is put two wheels on the front and a seat (low to the ground) and hook a ping-pong table sized solar panel to it and you are off to the races. I once saw one go 70 MPH...
I have been designing a one wheel per foot transporter that with these large motors can probably accelerate you up to 30mph. It will be able to go over some rough terrain and smooth terrain. Only if I had the money or the will to start...
nice! good idea because if it can't go up a certain slope, you can just get the motors to halt (maybe use worm screws?) and just walk up

just watch the sides of the street for sombody discarding an old powerwheels truck and sha-bang.. making it autonomous would be cool though. I once put a truck battery in one of those things and I know it had to do like 30MPH with a 7 year old behind the wheel and it would run strong even uphill for a good 4 hours too. it was great untill the neighborhood kids overloaded it and striped the gearboxes out!


A windmill that uses the wind as you drive? Possibly the 2nd+3rd laws of T.D might have something to say about that.

Perhaps a windmill that uses the wind when stationary though..

I believe its the 1st law actually--conservation of energy. Either way...thermodynamics is just trying to keep us down...

oops, yup:

0th law -  objects in thermal contact tend to the same temperature
1st law - conservation of energy
2nd law - change of entropy must be > 0
3rd law - as T goes to zero, entropy goes to zero.

Hmm, not exactly sure why I wrote 3rd  - I honestly meant to write 1st and 2nd, both are the bane of the "free energy" fruitloop community.

This is the 21st century, yet I STILL see "qualified" electrical engineers  thinking they can get free energy, how horrifiying (a la "Lutec..")

ho ho ho whats this? even a walking chair?  sound like my kinda challenge! :D
