15/March Motor
experiments
Objectives:
1. Find a method of
transmitting the data of the sensor to the computer by wireless network.
2. Find the specification of
required motor which is able to provide enough power for the WIG craft.
Quantify and set
formula for the force and power.
3. Find a motor which is
compatible with the given control system in the WIG
assumption:
a. Whether
the power of motor is controlled by the PWM, if it is, then find the
corresponding wires.
b. If it
is not related to PWM, then find how they control the motor.( Probably analog
signal?)
4. If cannot find the motor,
or cannot understand the given circuit. Then find a arduino board,
do experiments
with the given control system. Test and record all the pin's output,
then use the
arduino board input the remote control system's output pin, and write codes
to
output
corresponding PWM signal to control the new motor.
Experiment Result:
Test data:
We have two chips, one is for
receiving the signals from the remote controller. We name it as Chip A.
The other one is to transmit
the remote controller signals to motor controlling signals . We call it Chip B.
Chip A output port :4 same
removable plastic connectors.
Two are
used to control the Elevators, one is used to control the rudder.
The
fourth one controls the motor.
Chip B input : Three signals (
orange,red and brown wries)
: Output signals( red , yellow and black)
