2-DOF RB-421 pan and tilt kit is a cost-effective, positioning-precise and lightweight kit which can be used both inside and outside.

It features moving vertically and horizontally. Not only can the attached camera record images, but recognize images and implement positioning tracking. With an IR sensor or Ultrasonic sensor, it forms an all-in-one detecting device to be able to sense the change of ambient surroundings by which the robot can detect and avoid obstacles. By the Arduino controller, a color searchlight can also be added to complete a new work.
