Description

technical field [0001] The invention belongs to the technical field of robot drivers and industrial automation drivers, and more specifically relates to a graphene electrode dielectric elastomer driver. Background technique [0002] At present, with the continuous development of human production and life, the demand for robot technology continues to increase. In extreme and dangerous engineering environments where humans are not suitable, robots provide great convenience to humans. At present, the commonly used driving forms of robots include: electric motor drive, pneumatic drive, hydraulic drive, etc. These traditional driving methods have problems such as low energy density, large volume, large mass, small output force, low safety factor, poor environmental adaptability, low reliability, and inflexibility. It is difficult to achieve biological In addition, the traditional driving method is generally based on a rigid structure, which is difficult to meet the flexibility ...
