What's New and Improved in navX2-MXP

• Significantly improved yaw accuracy and stability, even during Extreme inertial events. navX2-MXP features very high-accuracy orientation (yaw/pitch/roll), with minimal yaw drift of ~0.5 degree per minute when moving, and < 0.2 degrees/hour when still. navX2-MXP is incredibly stable, and averages a yaw drift of only 2 degrees per DAY when still. navX2-MXP's new Industrial-class ISM330DHCX IMU sensor handles high rotation (4000 degree/second) and impact (16G, operates in higher temperature environments and can survive extreme shock events (20,000G).
• Rapid (5-second) auto-calibrating startup.
• navX2-MXP features an upgraded 180Mhz 32-bit floating-point ARM processor, the new sensors, and new state-of-the-art software algorithms which take navX technology to the next level, including a blazing-fast 416-Khz Kalman Filter, enhanced sensor calibration and algorithms which fuse gyro, accelerometer and magnetometer data into a “9-axis heading”.
• As a result of these upgrades, the accuracy of Velocity Vector Measurements and Displacement Estimates is also improved.

The navX2-Micro is the greatest sensor for orientation in competitive robots. nnavX2-Micro is a second-generation 9-axis inertial/magnetic sensor and motion processor. Designed for plug-n-play installation onto robots such as those used in the WorldSkills Robotics, FIRST Technology Challenge (FTC) and the FIRST Robotics Challenge (FRC), navX2-Micro helps build better robots by adding sophisticated navigation capabilities. Significant improvements over the classic navX2-Micro allow for more accuracy, decreased yaw drift, and faster boot time. navX2-Micro includes software algorithms for enhanced sensor calibration as well as KalmanFilter-based data fusion combining gyro, accelerometer, and magnetometer data into a 9-axis heading and high-quality magnetometer calibration including magnetic disturbance detection.
  
In addition to being an Inertial Measurement Unit, navX2-Micro capabilities are referred to within the aerospace industry as an “Attitude/Heading Reference System” (AHRS). Studica brings this high-tech AHRS capability to FIRST teams – to use, learn, and explore. navX2-Micro is a key component of Studica’s ongoing efforts to make state-of-the-art navigation technologies used in drones and autonomous vehicles (e.g., the Google Car) available to robotics students and enthusiasts as low-cost, open-source products.

Improvements over navX "Classic":
navX2-Micro features a new set of IMU & Magnetometer sensors with superior sensor specifications to those on the MPU-9250 sensor. This board has a faster 180Mhz microcontroller and an optimized startup time at 5 seconds versus 15 seconds. In addition, it has a completely new Kalman Filter-based Sensor Fusion algorithm running internally at a blazing fast 416Hz. 

RoboRIO Installation
It's recommended to connect to the RoboRIO using a USB Mini-B type (Male) to USB A type (Male) connector, navX2-Micro can receive both power and also communicate with the RoboRIO. This preferred installation method allows the navX2-Micro circuit board to be placed up to 6 meters away from the RoboRIO.

IMPORTANT NOTE:  To avoid having the navX2-Micro reset due to a RoboRIO brownout, connecting the navX2-Micro to the RoboRIO via USB is highly recommended.

The Studica 360 Degree LiDAR is a 2D LiDAR that rotates 360 degrees to achieve high accuracy, stable performance, high-frequency and high-precision distance measurement. It's ideal for robot navigation and obstacle avoidance.

The Cobra Line Follower Array provides 4 X QRE1113 IR reflectance sensor mounted on a 9mm pitch Each sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate.

The Studica Line Sensor Board consists of 4 IR LED/phototransistor pairs, making it a great detector for a line-following robot.  The Line Sensor Board allows the robot to tell objects or surfaces apart based on how dark or light they are. It shines a beam of infrared light out onto the object, and measures how much light is reflected back.

Each sensor provides a separate analog voltage output. The sensor board is an infrared emitter/receiver that is able to differentiate between a dark surface (with low IR reflectivity – 3.3V to 5V) and a light surface (with high IR reflectivity – 0V to 0.5V). However, this range can vary depended on the installed height of the sensor board. 

The optimum height distance is 3-5 mm; however, the reflectivity values will change depending on distance. A daylight filter is built into the sensor.

• 5VDC operating voltage (recommended)
• 70mA supply current
• Optimal sensing distance: 0.125" (3mm)

The Sharp IR Distance Sensor GP2Y0A21YK0F uses a beam of infrared light to reflect off an object to measure its distance. Because it uses triangulation of the beam of light to calculate the distance, it is able to provide consistent and reliable readings which are less sensitive to temperature variation or the object’s reflectivity. The sensor outputs an analog voltage corresponding to the distance of the object, and can easily be read using an inexpensive analog to digital converter (ADC) chip.
