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.
This is a snap-action micro switch with hinged roller lever and terminals for easy wire connection.
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.
This pack contains a noncontact distance measurement module that works at 42 kHz to transmit a digital signal to the TETRIX PRIZM Robotics Controller. The module detects the range of an object within 3 to 400 cm, enabling your robot to sense its surroundings. Comes with a mount, connecting sensor cable, and the hardware for attaching the sensor to the TETRIX hole pattern
This pack contains a line-tracker module that transmits a digital signal to the TETRIX PRIZM Robotics Controller, enabling a robot to follow a black line on a white background or vice versa. The sensor consists of two parts: an IR-emitting LED and an IR-sensitive phototransistor. Comes with a mount, connecting sensor cable, and the hardware needed for attaching the sensor to the TETRIX hole pattern.
Offers a replacement for a lost or damaged Ultrasonic Sensor Mount.
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.
The MXP-MD2 is a next-generation high performance Motor Controller Driver and Sensor Adapter with many added features to make it ready to use in your robot project. The included VNH5019ATR-E Motor Controller ICs are very robust with high current output and several important protection features. Many other I/O options have been incorporated into this design to make it extremely easy to interface to several different sensors.
The navX2-Micro is the greatest sensor for orientation in competitive robots. navX2-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.
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.
Keep that swarf out of your delicate electronics! Protect your navX-Micro and navX2-Micro from debris and impacts with this simple case.
The Sensor Kit for the DART Linear Actuator includes two hall effect sensors (am-3313), an aluminum mounting bracket, and associated hardware. The hall effect sensors are intended to be used for end of travel sensing.
This kit is designed to be used with the 12" DART (am-3072a) or 6" DART (am-3076a) linear actuator. Both bracket lengths are included.
Be sure to position the sensors at a location so that the DART lead screw does not travel as far to bottom out the brass nut at the end of stroke.
It is recommended to run this actuator with hall effect and/or current protection as it is possible to stall or "stick" the lead screws when stalled against a hard stop at both ends of travel. It's recommended to use the the hall effect switches to limit travel of the actuator from the end stops. When using faster ratios it may be possible to overrun the limits slightly and programming methods may require ease into stroke ends. If you are not able to program these functions we recommend using a Talon SRX (am-2854) which has on-board switch monitoring and current protection.
Be sure to assemble the DART so that the magnet on the Back Bearing is located under the location that the hall effect sensor is mounted.
Whether in the shop or in the field, when you need to check sensor functionality the Sensor Screen will help. This self-contained device will let you plug in robot sensors and view their readouts separate from your robot, providing crucial troubleshooting information. Future sensors can be added through an SD card, protecting your Sensor Screen against obsolescence.

A better way to Hall Effect is here. Now you can easily see when the magnet is close to this hall effect sensor as there is a blue LED, on to know it's powered, that will turn off when the magnet is near. This Hall Effect is designed specifically for FRC use and is featured in the DART, Sensor Kit (am-3077) for the DART, 12" Actuator Kit (am-3072a) and DART, 6" Actuator Kit (am-3076a). The sensor works with either pole of the magnet and reading the sensor is easy, 5v means component is safe to move 0v means the magnet is under it.
This hall effect sensor board has four mounting holes. You can use two for mounting and two for a cable tie to hold the connecting cable in place.
