remote controlled car
Remote controlled car made out of a coke can. Works much better than usual straight line/reverse steer car from which the radio is taken; turns round & round on the spot in reverse. To make the car work, it is essential to understand the rocker principle. The rocker levers one end of the coke can off the ground. Works better with a steel coke can than an aluminium one because it has more inertia.
This is how you make holes in the middle of a coke can
The next one uses the radio from a car which has forward/reverse/stop options, it uses a device called an omniwheel
.
It steers by rotating the omniwheel clockwise/anticlockwise. One of the most difficult aspects of steering mechanisms is making them self-centering, the omniwheel solves this problem. The car can be controlled very well although it has no forward/reverse/stop control.
If you convert a car to articulated steering it corners much faster, almost within its own length
it must have a self-centering servo. Because its appeal doesn't depend on speed but manouverability it can use a very economical battery arrangement. Because you can put the batteries anywhere you can get very good weight distribution.
