Self-contained hydraulic cylinders have gained popularity in the recent years but have not been implemented for high power articulated hydraulic manipulators. This paper presents a novel concept for an electro-hydrostatic actuator applicable to large hydraulic manipulators. The actuator is designed and analyzed to comply with requirements such as load holding. overload handling. https://www.roneverhart.com/D-Addario-EJ10-Extra-Light-80-20-Bronze-Acoustic-Guitar-Strings-10-47/
