In recent years, the field of humanoid robotics has undergone rapid transformation, driven by advancements in artificial intelligence, materials science, and mechanical engineering. No longer confined to laboratories or exhibitions, humanoid robots are steadily moving toward real-world applications across logistics, manufacturing, healthcare, and service industries. Among the many technological breakthroughs fueling this shift, one stands out as especially strategic and challenging: the development of dexterous robotic hands.

As the pace of technological advancement accelerates, humanoid robots are no longer confined to the realm of science fiction. From assisting with household chores and elder care to contributing to manufacturing and logistics, these intelligent machines are becoming increasingly present in daily life—enhancing efficiency and delivering convenience.

Dexterous robotic hands are one of the most critical components in humanoid robots. Human hands feature 23 degrees of freedom (DOF), weigh only about 1/150 of total body mass, and contribute to 54% of the body’s motion capabilities. Similarly, robotic hands serve as key end-effectors for executing tasks and interacting with the real world.

OpenArm, an open-source robotic arm project, has recently gained rapid popularity in the robotics community. Its success stems from precise positioning and excellent design. Targeting educational, research, and small-scale automation scenarios, OpenArm offers a complete open-source ecosystem—including mechanical structures, control electronics, and software algorithms—significantly lowering the barrier for robotic development.
