The Radar Car
- first version
The first version of my radar car. This one used the concept
of the adder/substractor to vary its speed instead of a mechanical
gearbox. The car didn't work very well for a few reasons :
- There was more friction on one side of the driving differential
and the car kept on turning.
- There was not enough difference between high speed and
low speed to notice (but I think I'll try again later the
adder/substractor, the concept is interesting).
- I used rather low-power, visible light leds so the radar
sensitivity was too low.
- The bumper design was flimsy.
Hence the new version...
