FTC Set Up the Mecanum Training Platform 20231025

Why

• Create a program testing platform. We want to create programs that we can copy to the competitions robot without modification.

Check Points

Check Point 1

Rename the Controller Hub

• Robot Controller Settings
  • Robot Controller Name is OrRAS11-RC

Check Point 2

Down loading the Mecanum Demo Program

• Locate the the Drive Mecanum program in GetHub and copy it to your laptop. You will need internet access for this step
  • DriveMecanumEpp.java
• Load the program into your robot

Check point 3

Pair the Driver and the Control Hub

See

• [https://www.youtube.com/watch?v=XOtzRAZ5HyM youtube of Connecting a Driver Hub to a Control Hub ==

Check Point 4

Connect and Configure the motors

• This program will not run correctly because it robot hardware needs to be configured for a different motor configuration.
• Configure these motors with the same I2C connections and motor names as the competition robot.
• Change the motor names in the java program to match the configuruation
• Build
• You can not test yet because the Driver Hub has not yet been configured.

Check Point 4

Update the Control Hub

• See Updating Control Hub
• Use the Google Chrome we browser - TBD double check
• You will need to install a program name REV Hardware Client
• Test

Update the Driver Hub

• See Updating Control Hub
• Test

Configure a Color Sensor

Color Sensor Demo Code

• Read and display the value of a color sensor]

Find this line of code

  colorSensor = hardwareMap.get(NormalizedColorSensor.class, "sensor_color");

Physical Connection

• Connect Color Sensor to one of the I2C ports - 1 in this case

Configuration File

• Control Hub
  • I2C Bus 1
    • Port 0 REV Color Sensor V3
    • sensor_color

Example HW color senso configuration entry. Change ColorV3 to sensor_color for our examples.
