Your
OUTPUTS
screen now looks like this:
The change to the screen is subtle: the little arrow to the right of the ‘100’ on the CH2 line now
points to the left instead of the right, indicating in ‘inverted’ response.
In the next section we will check the operation of the ‘Elevon’ mix to see if and where we may
need to invert output channels to obtain correct response to our stick inputs.
Troubleshooting the Drive Mix
Find a safe place to test the robot drive, unplug all weaponry, and power up the radio and robot.
Try a little gentle forward motion and a slow turn to the right.
Given a forward command, only one motor responds -- given a right turn
command, only the other motor responds.
You have both transmitter mixing and on-board mixing on the
controller turned on. Turn off the on-board controller mixing.
Given a forward command, robot backs up straight.
Invert the response for both of the motor control channels: CH1 and
CH2.
Given a forward command, robot spins in place.
Invert the response for the channel that feeds the controller for the
motor that is backing up.
Given a right turn command, the robot turns left.
You have the left and right motor controllers plugged into each other’s
receiver ports. Unplug the controller connectors from the receiver and
plug the connector that was in CH1 into CH2 and vice versa. You may
have to invert response for one or both channels to get correct
forward/reverse motion, but the turning control will be correct when
you're done
