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 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.
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.
Includes 2 VNH5019 Motor Controller ICs,
2 Enable Inputs, 2 direction inputs, one PWM input per channel up to 20Khz
Up to 12A Continuous output per channel, 30A peak current short ms duration
The Studica Multi-Mode Smart Servo features all-steel gears and large amounts of torque. This angular programmable Servo can fill a variety of roles on your robot or project. In standard mode, it operates on a +/- 150-degree range. Using the Studica Smart Robot Servo Programmer (sold separately) the Multi-mode Smart Servo can be configured to run in continuous, standard, and custom angular mode. In continuous rotation mode, the servo will have proportional speed control based on the PWM signal that you send with your servo controller.
