    Get ready to bring your robotic dreams to life with the RobotGeek Continuous Rotation Servo! This metal-geared servo is perfect for building robotic rovers, spinners and more! And because these servos use a standard PWM signal for control, they're easy to directly interface with microcontrollers like the Arduino!

    Rail and Bracket System

    The RobotGeek Rail System makes it to mount your servo to your robot. Each servo fits in an easy-to-cut hole pattern and are molded to securely hold M2 nuts. Just use the included hardware and you're ready to go! This convenient mounting system will also allow you to attach RobotGeek Servo Side Brackets which will increase your mounting capabilities, and even let you attach servos to other servos.

    PWM control

    These servos can be controlled via a standard PWM signal, the same one used in most hobby servos. Instead of controlling servo position, you are able to control servo speed (i.e. a 0° signal = full speed counter clockwise, 180° signal = full speed clockwise, and a 90° signal = stopped). The servo even has an external potentiometer for adjusting the deadband on the servo so you can calibrate it.
    This signal is easy to understand and can easily be generated by most microcontroller systems. The Arduino environment even has a built in library for easily working with PWM servos.

    Ease of Use with the RobotGeek Sensor Shield

    The Arduino does a great job of controlling PWM Servos, making it ideal for a variety of robotic projects. But sometimes powering these servos can be problematic. Powering servos from the Arduino's 5v regulator leads to underpowered servos, limited by both voltage and current. With other sensor systems, connecting a servo to an external power supply requires multiple cables or boards, defeating the purpose of a sensor shield. The RobotGeek Sensor Shield solves this problem with 2 jumpers to control the output voltage of the 6 PWM channels on the Arduino. Just move the jumper from '5V' to 'Vin' ans your servo will start to draw power from your Arduino's input voltage supply. Just plug in a 6v power supply into your Arduino, and you'll be able to power and control 6 RobotGeek Servos with no problem!
