Hydraulics driven Manipulators

Serial 6-links Hydraulic manipulator for active power line maintenance
Paralell 6-links Hydraulic manipulator (motion base)

Manipulators driven by fluid power are well used where both of high-power and fast-response are required. There are two types, serial and paralell.To extend the high performance of fluid power driven manipulators, it is dispensable to apply Robust control shemes.
