Leaderdrive (also known as Green Harmonic) is China's largest harmonic-reducer manufacturer and ranked second globally, having passed Tesla supply-chain verification and naming AgiBot and UBTech among its humanoid robot customers. In 2026 the company signed a framework agreement with Minth Group for a North American joint venture to manufacture humanoid joint-module assemblies.

Leaderdrive has grown rapidly to become the dominant Chinese supplier of strain-wave harmonic reducers, competing directly with the long-established Japanese market leader and establishing itself as the number-two player globally by volume. Its successful passage through Tesla's rigorous supply-chain qualification process is a significant credibility marker, and its named relationships with humanoid OEMs AgiBot and UBTech demonstrate active deployment of its reducers in commercial humanoid programs. The 2026 framework agreement with Minth Group to establish a joint venture in North America for humanoid joint-module assembly represents a strategic move to localize production closer to emerging Western humanoid manufacturing hubs. Leaderdrive's combination of cost-competitive Chinese manufacturing, proven product quality, and growing customer diversification positions it as a key challenger to Japanese reducer suppliers in the global humanoid supply chain.
