NRS-885 High Torque RC Servo Motor with metal gears

Introduction

NRS-885 is a high torque metal gear servo with dual ball bearings. It gives 6kg-cm torque. This servo motor is ideal for making your own hexapod, walking insects, heavy duty sensor / camera pod. Servo motors are used in radio control models. They are very useful in robotics applications because of there small size and low cost. Servomotor has built in motor, gearbox, position feedback mechanism and motor controller. The servo motor can be controlled to move any position just by using simple pulse controlling. This motor has three wire interfaces for control and power supply. All the robots from NEX Robotics support this servo motor.
