The 90 Degree Bracket is perfect for connecting two channels pieces at 90 angle from each other. Each side is 48mm wide to fit perfectly on the 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.

This kit is a tried and tested addition to the Climber in a Box. It is used as a secondary bracing point between the outermost piece of extrusion and the robot that the Climber is attached to. It also has mounting holes to accept our Peanut Extrusion, which can be used to brace two Climber arms together across a robot.

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)
