Continuous rotation HDD servos will give your robot mobility by rotating 360 degrees.
These servos are also called "modified servos", because they will rotate continuously in a circle, making them perfect for attaching wheels. Wheels are not included with this servo, however check out Continuous Rotation HDD Servo with Wheel for servos with wheels - or the Servo Wheel (2 Pack).
HEAVY DUTY DIGITAL SERVO MOTORS
Inside the HDD servo-motors are metal gears and real ball bearings that lift 19 kg/cm! These servos have enough strength to let your robots walk, move or lift. We engineered these servo motors to be tough from years of R&D, check out our demonstration video!
