35KG.CM CF35-12 Bus Servo, High Precision And Large Torque, Aluminum Alloy Case, With Programmable 360° Magnetic Encoder, Multiple Operation Modes Switchable
CF35-12 is a programmable dual-axis constant force serial bus servo with a stall torque of 35KG.CM. It has an all-aluminum alloy shell and an external high-strength aluminum alloy steering wheel. It uses a 360° high-precision magnetic encoder and can perform angle control within a 360° range. It can set any angle as the servo center position through program control; It can also be switched to continuous motor mode, multi-turn continuous rotation and other working modes, with built-in acceleration start-stop function, making the action smoother.
Each bus servo has two interfaces, allowing the servos to be connected in series. Theoretically, up to 253 servos can be controlled simultaneously, and each servo can obtain its current angle, load, voltage, mode, and other information. It can be used to build multi-axis small-volume steering robot projects such as quadruped, hexapod, and robotic arm, and easily handle large objects.
