General Design Notes
Car Body:
-
Servo Specifications
-
The servos only accept 5V. They DO NOT accept anything HIGHER than
5V.
-
If you have the black servo: +5V attaches to the red wire, 0V attaches
to the black wire, 0-5V PWM signal attaches to the white wire.
-
If you have the red Multiplex servo: +5V attaches to the red wire, 0V
attaches to the brown wire, 0-5V PWM signal attaches to the orange
wire.
-
The pulse width should vary from about 1ms to 2ms and the period is around 10ms
to 15ms.
-
Motor Specifications
-
RC motors generally work off of 7.2V ni-cad batteries.
-
When stalled, they can draw more than 20A.
Siemans CPU Board:
General Software:
-
Learn how to use the interrupts and all the useful peripheral hardware in the
Siemens CPU. In general, control code should be time
triggered.
EMF Proximity Detector:
Optical Detector:
-
We have an excellent optical detection solution using a Hamamatsu IC and a photo
diode.
-
Possible applications: Speed/distance detector, crossing detector, line
detector.
Organization:
-
We have ribbon cable and connectors in order to prevent your cars from looking like
this... This car may have won 2nd place in 1999,
but it looks ugly
and is a mess to work with. Hopefully it will be easier to organize
the cars by using ribbon cable.
