HELP!! Our Robot Is Not Driving

[Astrophysicist]

Hello,

We have been trying to get our robot to drive in Java, which successfully worked before on our last robot but now for some reason does not work. On our driverstation all of the LEDs (robot code, communication, joystick) are green but when we deploy the code, nothing happens. Everything on our sidecar is green except for the Victors which are flashing orange. We double-checked the PWM ports and they are plugged in properly. Yesterday we FTP'd our code to the CRIO and it pinged so we knew it was communicating, but we are still getting the problem, "Host may nnot be on same subnet as robot. IP address: 10.47.77.9 , subnet: 255.255.255.254." still presists. We checked our network and the subnet should be 255.255.255.0 .

HELP!!!

The flashing lights on the Victors mean they aren't getting a PWM signal. Here are some of the most common causes:

Is there communication with the Driver Station?
Did you enable the robot in Teleop mode on the Driver Station?
Are all three power LEDs on the Digital Sidecar brightly lit?
Are the PWM cables fully seated in the Victors? It can be very hard to get them correctly seated. Have several people try several times.

theRobot.ArcadeDrive(moveValue,rotateValue); //rodbo0t drivinDm

Is this the exact code you ran? This line won't compile because the ArcadeDrive method doesn't exist in RobotDrive. The correct method is arcadeDrive (lower case a).

"Host may nnot be on same subnet as robot. IP address: 10.47.77.9 , subnet: 255.255.255.254." still presists. We checked our network and the subnet should be 255.255.255.0 .

This is a known issue with older JREs, they detect the netmask improperly. If the code successfully downloaded to the robot, you can ignore that message.
