Our programming language is Java, but any combination of code seems to not help.
Any ideas?
How is your pressure switch wired? Which pins in the cable go to the terminals on the switch? Can you do some debugging to determine whether the code is actually reading the state of the DIO input? If you disconnect the switch, does the value change? How about if you short across the switch with something conductive?

What color is the Spike lighting up? It'll be yellow when power is applied but no command is being given to turn it on, and it'll be green when the relay is activated (the associated Digital Sidecar relay LED will also turn green).

Have you enabled the robot?

Do you have 12v power to the Digital Sidecar?

What is the Robot Signal Light doing?
