RC robot car using DPDT switch

Remote controlled wired robot car

one of my favourite and easiest design of making a robot car

components:

1) 2 nos. dpdt switch

2) 4 nos. 500 rpm or above geared dc motor 

3) 4mt or more strip of wire

4) 12v dc supply

 

first part is to make the chasis for the car

take a square plywood sheet or anything which you want as a chasis,then make holes on it to fit the four geared motors and then fix the motors in the holes

 next is the connection of dpdt switvhes

connect it as shown in diagram

connect all the positive ends of 1st two motor of one side to one dpdt switch and the other side to other dpdt switch

connect it to the motor now by a strip wire 

for power supply, 12v  laptop charger or direct 12v supplies can be used

controls

forward : press both the switch forward

backward: press both backward

right : press the only right one forward

left: press only the left one forward

this was a simple dpdt switch controlled robo car
