Humanoid Robotics

Humanoid robotics combines AI and semiconductor technology to enable real-time perception, decision-making, communication, and motion control in human environments. Unlike industrial robots, humanoids navigate dynamic spaces, interact safely with people, manipulate varied objects, and adapt to changes. This requires advanced electronics, software, and semiconductor solutions. Modern humanoids rely on five key subsystems: compute, sensing & perception, actuation, power, and connectivity, enabling autonomous perception, decision-making, and task execution.

The compute subsystem acts as the robot's brain, enabling AI, machine learning, motion planning, and sensor fusion. It processes data from cameras, depth sensors, inertial sensors, and more using high-performance processors and neural units. AI inference at the edge allows real-time decision-making without cloud reliance. The sensing & perception subsystem provides environmental awareness through image sensors, depth technologies, radar, tactile sensors, and audio inputs. Combining these modalities helps robots detect obstacles, identify objects, estimate distances, and navigate complex environments.

The actuation subsystem converts digital commands into physical movement. Humanoid robots use numerous independently controlled joints across their body, each needing motor-control electronics. These systems use microcontrollers, gate drivers, power semiconductors, sensors, and feedback devices for precise motion. Advanced robotic hands add complexity with tactile and force sensors for tool manipulation. The power subsystem supports these functions with battery management, power distribution, voltage conversion, and charging infrastructure. Efficient technologies like silicon MOSFETs, GaN, and SiC devices enhance energy efficiency, reduce weight, and extend operating time.

The fifth building block, connectivity, enables communication within the robot and with external systems. High-speed networks facilitate data exchange between sensors, actuators, control units, and infrastructure like fleet-management platforms. Key trends include Physical AI, sensor fusion, dexterous manipulation, distributed computing, and energy-efficient actuators. The main challenge is ensuring reliable, safe operation in unstructured environments where robots must perceive, reason, and act in real time. Adherence to standards like ISO 10218, ISO/TS 15066, IEC 61508, ISO 13849 and IEC 60204-1 ensures safety, reliability, cybersecurity, and regulatory compliance as robots scale from pilots to commercial use.
