BE THE BEST, BE THE FIRST
The Brain Plans.
The Joint Responds.
HIGEN Smart Driver (Drive+) is not simply a motor controller — it is an actuator-level distributed intelligence (Embodied Intelligence) platform that performs sensing, proprioceptive estimation, active impedance compensation, and <100ms ultra-fast local edge response.
98% high-efficiency switching & 30% smaller system footprint
Real-time estimation of external torque and nonlinear friction
Parallel processing of motion, sensor, and communication for near-zero latency
Instant torque reduction and compliant yielding response upon collision
The Brain Plans. The Joint Responds.
HIGEN Smart Driver (Drive+) is not simply a device that spins a motor — it fully integrates sensing, estimation, compensation, and real-time control inside the joint, a local intelligence platform that lets the joint react instantly to external force and impact without waiting for high-level AI judgment.
Conventional Motor Drive vs. HIGEN Smart Driver
| Comparison Criteria | Conventional Motor Drive | HIGEN Smart Driver (Drive+) |
|---|---|---|
| Control Objective | Execute position/velocity/current commands | Real-time joint state & disturbance awareness |
| Sensor Feedback | Single motor encoder feedback | Dual 24-bit Encoder + IMU sensor fusion |
| Control Processing | Dependent on central high-level controller | Local edge control inside joint (<100ms) |
| Collision Response | Stop after collision or delayed error recovery | Instant collision detection & active torque yielding |
| Compliance & Force | Fixed rigid position control | Smart Force Control & dynamic impedance |

Drive+ 4 Core Hardware & Control Functions
Dual 24-bit Encoder
Measures the motor shaft and output shaft simultaneously at 24-bit resolution to estimate the joint's real position, torque, and transmission error in real time.
Integrated IMU Sensor
Detects acceleration and posture changes inside the joint in real time to perform gravity compensation and shock-mitigating motion while the robot walks.
Intelligent Force Control
Goes beyond simple position control to process torque control, active impedance control, a disturbance observer (DOB), and nonlinear friction compensation in real time.
Multi-Core Processing
Minimizes latency by running the high-speed motor control loop, sensor fusion algorithms, and industrial communication protocols in parallel on independent cores.
