The phalangeal finger features an actuator. Various systems and methods allow for a smaller volume actuator, which in turn allows for a smaller finger and / or more space for other features of the finger. The actuator includes a motor that causes a worm gear to rotate along a fixed worm wheel. The worm gear is integral with an output shaft. The worm gear climbs along the worm wheel to cause the finger or finger segment to rotate. The arrangement of the actuator parts allows for axial forces to be transmitted in first and second directions that respectively correspond to open and close rotations of the performing finger.

The application relates to the technical field of robots, in particular to a dexterous hand and a robot to solve the problem that a dexterous hand cannot simultaneously have high flexibility and small size due to a side swing structure. The dexterous hand has independent swing functions of small fingers and / or ring fingers through at least one first side swing driving assembly and one second side swing driving assembly, and the index finger also has an independent swing function. The extension direction of the first side swing driving assembly is parallel to the extension direction of the finger when the first side swing driving assembly is arranged to stretch, the extension direction of the second side swing driving assembly is crossed with the extension direction of the index finger when the second side swing driving assembly is arranged to stretch, and one end of the second side swing driving assembly extends towards the middle finger, so that the mounting position of the thumb is closer to the middle finger and the index finger. The compact structure of the dexterous hand enables the multiple fingers of the dexterous hand to have independent side swing functions while also considering small size, so that the dexterous hand is suitable for more extensive application scenarios.

The invention discloses a soft dexterous hand posture sensing system based on an IMU (Inertial Measurement Unit) and an integration method thereof, belongs to the technical field of robot hands, and particularly relates to real-time sensing of posture and motion of a soft dexterous hand. The problem that in the prior art, due to the fact that the finger size of the soft dexterous hand is small, a driver and a sensor are prone to mutual influence is solved. And the signal stability of the sensor is difficult to guarantee due to the limitation of the process and the material. And the problem that the existing sensor scheme is difficult to sense all attitude information due to more degrees of freedom of soft finger joints is solved. The system comprises five IMU finger flexible sensing modules, an IMU center acquisition board, a control board and an upper computer. The IMU-based soft dexterous hand posture sensing system and the integration method thereof are suitable for real-time sensing of the posture and motion of the whole soft dexterous hand.
