someone please help me with my solar powered rc car school project?

We Answered:

first what are the rules
.for standard try to optimize the largest surface for the cell on the car (given the rules size limits) I use to go for full flat top

. weight is a issue because not much power there get the lighest material for your car chassis - personally I'd use foam or plastic

.power all solarcells given they're .5watt to 1watt each link them on series (my car got 6volts total )

.drive system the motor if your going brush I use a 370motor from an rc heli for brushless I would go for the lowes KV I can find like 1000KV or 900KV

Gearbox typical an 1:16 or 1:20 ratio if not belt drive of the same ratio

electronics buy your self a radio set 2ch from a hobby store transmitter and receiver
a electronic speed controller that matches your motor of choice and a servo at lest the 9g type for your steering.


if you can find a ready to run rc car that fits the description you can use it but you got to strip all uneccesary parts to save weight

lastly aerodynamics be low to the ground alt flat as possible

optional if the rules permit.some nimh batteries series that to a diode (use as recerve recharge by the solar ) series the battery to diode then parallel it to the solar the rest plug it to your speed controller.

Steam, Wind, Or Solar Powered Project?

We Answered:

A Zeppelin would be very nice I think. It could try to be in the same place measuring the velocity and direction of the wind and canceling it with motors powered by solar light. Or use the solar power to warm the air inside of the Zeppelin, or generate steam to keep the Zeppelin up. Or could even use the wind power to do it.
