nominal so operating current is 2.2A so at 12V this would 26.4W

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 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.

The Studica End Piece Plate is commonly fastened to the inside end of the U Channel. As with the other Studica Robotics building components, it has the common hole pattern which makes it easy to connect to other structure with very little or no additional machining required. You can easily connect to other channel, extrusions, bushings, bearing, mounting brackets and more so you can quickly assemble and disassemble robots and automated systems.
