InstallationRoboRIO InstallationSecuring navX-MXP to the RoboRIONext, secure navX-MXP to the RoboRIO using two #4-40 screws, each with a length of 3/16thinch. You can also use a 1/4 inch-long screw if you place a small washer between it and the topof the navX-MXP circuit board.Image not foundSecuring the navX-MXP circuit board and RoboRIO to the robot chassisThe navX-MXP circuit board should be mounted such that it is firmly attached to the robotchassis. The quality of this mounting will be directly reflected in the quality of navX-MXPinertial measurements. To ensure quality, carefully follow these guidelines:The RoboRIO on which the navX-MXP circuit board is placed should be tightly mounted;it should be a part of the chassis mass, and should move exactly as the chassis moves.Avoid mounting the navX-MXP circuit board in an area of the chassis that might beflexible, as this could introduce vibration to the inertial sensors that does not representthe chassis inertial properties.The navX-MXP circuit board should be mounted in the center of the chassis, whichensures the origin of the yaw/pitch/roll axes truly represent the chassis center.Be sure to understand the orientation of the navX-MXP circuit board, relative to thechassis, and decide whether OmniMount is needed.Housing the navX-MXP circuit board in some form of protective enclosure is highlyrecommended, to protect it from damage. This should both protect the circuit board fromdamage, and provide strain relief for the cables that connect to the navX-MXP circuitboard.(Note that there are several other installation options available.)FTC InstallationNote: navX-MXP firmware version 2.2 or higher is required to use navX-MXP w/the FTCAndroid-Based Robot Control System.navX-MXP can be used with the FTC Android-Based Robot Control System released in 2015.Both power to and signaling to/from navX-MXP occurs via the I2C interface by way of the CoreDevice Interface Module (DIM) from Modern Robotics, Inc, as shown in the below diagram:11 |
