Magnetic Perception Architecture of KingKong Technology: DPT, DPB, and MPT Encoders

Beijing KingKong Technology Co., Ltd. (KingKong.tech, based in Changping, Beijing) specializes in high-precision non-contact angular position sensing for next-generation robotics.

In contrast to conventional optical encoders utilizing delicate glass scales, KingKong magnetic systems leverage patterned multi-pole magnetic targets coupled with differential Hall and magnetoresistive (AMR/TMR) sensing matrices.

This architecture provides complete immunity to shock, vibration, and dust while maintaining long-term zero-reference stability.

The DPT and DPB dual-channel rotary encoder series offer an integrated sensing package tailored for strain wave and planetary reduction gearboxes.

Housed in an ultra-low profile envelope starting at just 5 mm in thickness, two independent sensing tracks continuously track the high-speed input motor shaft position and the low-speed joint output angle.

This dual-loop perception allows direct real-time measurement of joint backlash, elastic transmission deflection, and thermal drift without external secondary sensors.

For miniature robotic end-effectors such as anthropomorphic dexterous fingers, medical tools, and compact pan-tilt gimbal units, KingKong produces the MPT ultra-thin single encoder series.

Featuring a minimum axial height of 5 mm and lightweight hollow rotor rings, MPT encoders provide up to 20-bit absolute resolution with refresh rates up to 20 kHz via BiSS-C and SSI protocols.

TPB Torque-Sensing Triple Encoders and MPP Large-Bore Sensors for Humanoid Joints

The emergence of collaborative robots and humanoid manipulation requires strict functional compliance and contact safety during physical human-robot interaction.

KingKong Technology flagship TPB series torque-sensing triple encoders address this demand by integrating joint torque estimation directly into the rotary sensing assembly.

The TPB sensing circuit monitors the differential phase displacement between three concentric magnetic tracks across an integrated joint flexure element.

This enables the robot motion controller to calculate external contact forces and joint torques with sub-arcsecond sensitivity, delivering instant collision safety stopping, sensitive impedance control, and direct zero-gravity hand guiding.

For high-load waist azimuths, hip abduction pivots, and shoulder flexion joints, KingKong manufactures the MPP series large-aperture hollow-shaft encoders.

With inner bore diameters from 50 mm up to 150 mm and beyond, MPP encoders provide ample internal clearance for heavy power cables, communication harnesses, and liquid cooling channels through the joint axis.

TS20 Micro Joint Actuators and Jumper Open-Source Bionic Robotics

In miniature robotics actuation, KingKong Technology has engineered the TS20 integrated tactile servo module measuring only 20 mm in diameter by 35 mm in length.

Within this thumb-sized cylindrical footprint, the TS20 integrates a high-efficiency permanent magnet synchronous motor (PMSM), a precision strain wave gearbox (50:1 or 100:1 reduction ratios), a triple-encoder sensing array, and an intelligent FOC servo driver board communicating via industrial

RS485.

Benefiting from low internal friction and transparent backdrivability, TS20 actuators produce peak torques up to 2.5 N·m while simultaneously functioning as dynamic force sensors, streaming real-time torque and angle telemetry over multi-drop RS485 networks at 1 kHz update rates.

Demonstrating the agility of TS20 modules, the Jumper (跳跳) open-source bionic crab robot incorporates 22 integrated TS20 tactile servos.

Jumper traverses rough obstacles, maneuvers in all directions, and executes vertical leaps over 400 mm in height with soft compliant landings via active impedance control.

Installation Discipline, Air Gap Tolerances, and Noise Immunity Guidelines

Dependable long-term performance of KingKong magnetic rotary encoders is assured through proper mechanical alignment and electrical shielding.

Unlike optical sensors requiring cleanroom conditions and strict axial shimming, KingKong encoders tolerate radial air gaps between 0.2 mm and 0.5 mm and axial float up to ±0.5 mm without loss of measurement resolution.

During assembly, technicians can initiate automatic runout and eccentricity calibration using KingKong diagnostic software.

By rotating the shaft through one calibration turn, the DSP maps magnetic field distortions and writes compensation vectors to non-volatile EEPROM, eliminating mechanical bearing runout errors.

To prevent electromagnetic interference from PWM inverter switching, BiSS-C and RS485 communication lines must utilize individually shielded twisted pairs with shield braids terminated directly to the drive controller chassis earth ground.
