Our robots Port 1 suddenly stopped working. We had the right motor for the Drive Train connected to this port. We initially thought it was the motor, but after swapping the motors, cables and ports we have identified that its the Port 1 of the brain that’s not detecting the motor or any other sensor. Same motor/sensor with the same cable is being detected on the other ports. Check firmware on VEXOS, everything is up to date.
Anybody else experienced this issue? Any suggestions? We have our qualifying tournament next week. Please help!
If you look at the Control Systems Manual that came with your robot it shows you the default connections on the brain. It will tell you that 1 and 7 are left side drive, 6 and 12 are right side drive 4 and 10 map to the front buttons and 5 and 11 map to the top buttons.
There are also bumper sensors you can plug into the the remaining ports to act as limit switches. The manual has all the details along with the demo program hookups.
Thank you for all your help! It worked fine yesterday, but today when we tried to run the Autonomous program, the robot started acting up. Upon restarting we got the error: “I2C error detected on Motor Port 1-3 Reconnect Motor” and it stopped detecting the morot on port 1.
I tried to forced update again, but this time its not working!
