Description:
As a high-torque programmable serial bus servo, it is equipped with a 360° high-precision magnetic encoder, which can realize 360-degree absolute angle control. With the program to control, any angles can be set as the middle of the position, and it can also be switched to the continuously rotating motor or stepper motor mode. The built-in acceleration start-stop function makes the action softer. There are two interfaces on each servo, which can be used in series. In theory, 253 bus servos can be controlled at the same time, and each servo can obtain its current angle, load, voltage, mode, and so on. It is suitable for robot projects, such as robotic arms, hexapod walkers, humanoid robots, wheeled robots, and so on, which require real-time feedback for closed-loop control.
At the same time, we provide an open-source 12-DOF robot dog model for this servo. You can download the model and project files of the open-source structure in.
Features:
-
Up to 253 servos can be connected in series at the same time (requires full power), and also can obtain feedback information from each servo.
-
360° magnetic encoder, larger angle control range.
-
High precision, the angle control accuracy reaches 360°/4096.
-
Any angles can be set as the middle of the position, which is convenient for assembly.
-
Acceleration start and stop function, the movement effect is softer.
-
Compact structure design and the product appearance are more beautiful.
-
6-12.6V wide-voltage input, it can directly supply power with the 2s or 3s lithium battery.
-
High torque, up to 30kg.cm@12V.
-
The working mode can be set by the program: servo angle control/motor model can be rotated continuously.
