    Multi-Mode Smart Servo

    #75002
    $23.99
    ( 2085 In stock)

    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.

    IR Range Sensor (10 cm to 80 cm) w/I2C female to TJC8 female cable

    #40117
    $13.99
    ( 1195 In stock)

    The 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.

    Includes 40cm I2C female to TJC8 female cable

    Cobra Line Follower Sensor

    #70151
    $9.99
    ( 1053 In stock)

    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)
