Bonsystems, a South Korea-based robotics startup specializing in core robotic hardware components, has secured an investment of approximately USD 3.7 million(KRW 5 billion). The funding round saw participation from Pathfinder H, Hyundai Investment Partners, and IBK Securities.

With this latest capital injection, Bonsystems plans to focus on strategic business expansion, including the advancement of core components in humanoid robot hardware, strengthening system integration capabilities, establishing a mass production framework, and building automated manufacturing facilities.

Bonsystems is currently centering its efforts on the design and development of key robotic components, particularly its proprietary cycloidal gear reducer technology. The company’s in-house developed cycloidal speed reducer, branded as BSR, achieves up to a 70% reduction in volume compared to traditional involute gear types, while still delivering high torque and durability—features critical for humanoid robotics applications.

Bonsystems stated, “This investment validates our potential to emerge as a leading robotic hardware platform provider, offering core hardware solutions essential for the era of AI and intelligent robotics.” They added, “We will channel the secured funds into our new humanoid robotics initiative, with the goal of establishing a full-scale production system for humanoid robot hardware.”
