Fangrui Product Details It Can Be Used To Build Wheeled Robots, 3d Printers, Etc. That Require Accurate Closed-loop Speed Control Or Stepper Control; It Can Also Be Used To Build Robot Projects Such As Quadrupeds, Hexapods, And Robotic Arms That Require Multiple Servo Motors (this Product Provides The Open Source Structure Model Of The Robot Dog In The Figure Below) Up To 253 Servos Can Be Connected In Series At The Same Time Uses A 12-bit High-precision Magnetic Encoding Angle Sensor. Compared With Carbon Film Potentiometers, The Usable Angle Of The Magnetic Encoder Is Expanded To 360, And The Resolution Is Increased By 4 Times. Since There Is A Between The Magnetic Encoder Element And The Radial Magnet And There Is No Friction, The Service Life Of The Servo Motor Is Effectively Extended The Speed And Acceleration Values Can Be Set, And The Movement Effect Is Softer The Plane Spacing Of The Dual- Steering Disc Is Optimized, And The Overall Structure Is More Compact, Which Can Make The Product Appearance More Beautiful Produc
