RDS3115 / LDX218 Servo เฟืองโลหะ แบบแกนคู่

RDS3115 MG Robot Digital Servo เซอร์โวมีแรงบิต 15Kg ที่แรงดันไฟฟ้า 6VDC และ 17Kg ที่แรงดันไฟฟ้า 7.2VDC

Features:

RDS3115 biaxially digital servos, is a robot designed digital servos, torque 15kg @ 6V (actual torque 17kg@7.2v), low noise, high linearity and smooth, controllable angle range of 180 degrees, breaking power can rotate 360 ​​degrees, especially suitable for all joints of the robot.

Instructions for use:

Which digital servo control board MCU MCU internal servo control, which is the main difference with respect to traditional analog servo, but control the same way, are the PWM pulse width regulator angle cycle 20ms, duty cycle 0.5 ms ~ 2.5ms pulse width corresponding to the level of 0 degrees to 180 degrees steering angle range, and linear.   

The biggest difference between analog servo lock function is a position, to a PWM pulse width, steering angle output can be locked until the next pulse to a different angle or power can change the angle (not having the analog servo function, analog servo position to lock the need to keep providing pwm signal).   

Further control of high precision, good linearity, consistent with strict control protocol, the output angle accurate and fast response is an important reason for good quality digital servos. Typically servo controller uses 500 to 2500 output value corresponding to the steering angle control the duty cycle of 0.5ms ~ 2.5ms range, so that the control accuracy of the theoretical value which digital servos may reach 0.09 degrees, and since the actual steering gear the gap between the groups exist, the smallest servo control accuracy which can reach 0.9 degrees or less, relative to the PC software slider control to adjust the amount of the minimum unit is 10, steering clear of rotating only reaction.
