Direct Drive Technology Limited

The application of robot joint has been widely used for more than decades. There are 4 core components in industrial robot joint: reducer, motor, driver and controller. The reducer in a six-axis-robot arm occupies approximately 20~30% of the whole cost. However, more than 50% of the wasted robot are caused by the high wear rate of reducer. Thus, the reducer is a critical and expensive component in traditional robot joint.
Our project aims to develop a new type of robot joint, which integrates with mature industrial technic and stable rare-earth magnet supply chain to achieve neo robot joint. The new robot joint can realize similar functionality without embedding complicated reducer.
The company name “Direct Drive” also implies the reduction of reducer and use motor as direct driving force.
At current stage, DDJ has developed a wheel joint for wheeled robots, which can be used for auto-driving cars.
