Flexible actuator for robot joints

Current situation of robotic dexterous hands: small inference, low speed, and poor ability to withstand impact loads

Ultra - micro spherical pump solution

Characteristics of the ultra - miniature spherical pump electro - hydraulic actuator:

1. The world's smallest spherical hydraulic pump in terms of volume.

2. Utilize the forward and reverse rotation characteristics of the spherical pump to push the push - pull rod to extend and retract, eliminating the need for a directional valve.

3. The actuator can be placed entirely in a closed elastic capsule, eliminating the hidden danger of working fluid leakage.4. The ultra - miniature electro - hydraulic actuator can achieve distributed layout.

Ultra - miniature spherical pump electro - hydraulic actuator - driven dexterous hand

One of the application examples: Electro-hydraulic actuator driven by the palm of the robot

Performance parameters:

Compared with the existing ultra - micro actuators of motor reducers, the advantages of the ultra - micro spherical pump electro - hydraulic actuator are as follows:

The speed is 2 - 4 times that of the existing ones.

The thrust is 2 - 4 times that of the existing ones.

The volume is 60 - 70% of that of the existing ones.

It can withstand shock loads.
