Parts Controllers
Parts controllers are embedded computing modules and system-on-module (SoM) platforms that serve as the computational brain of robotic systems. Rather than complete robots in themselves, they are specialized hardware components designed to handle perception, inference, motion planning, and real-time control tasks within a broader robotic or autonomous system. Products such as the NVIDIA Jetson Orin NX and Jetson Orin Nano Dev Kit exemplify this category, offering high-performance AI acceleration in compact, power-efficient form factors suitable for edge deployment. The market for parts controllers is expanding rapidly alongside the broader robotics and autonomous systems industry. As robots take on more complex tasks in manufacturing, logistics, healthcare, and consumer applications, the demand for capable, energy-efficient edge AI compute modules continues to grow. Industry observers expect this segment to remain a critical enabler of next-generation robotics, with leading semiconductor and computing companies competing to deliver ever-higher AI inference performance within tight size, weight, and power (SWaP) constraints.
