Can a flywheel based energy recovery and storage system be used for robotic manipulators?

This paper investigates feasibility of using a flywheel based energy recovery and storage system for a robotic manipulator. The incentive is supported by ever g

How can a multi-joint heavy-duty manipulator save energy?

The gravitational potential energy recovery and reutilization efficiency is greatly improved. The results show that the effect of energy saving is remarkable. Multi-joint heavy-duty manipulators, such as working devices of hydraulic excavators, are mostly driven by hydraulic cylinders.

How to reduce the energy consumption of a manipulator driving system?

There are two ways to reduce the energy consumption of the manipulator driving system. One way is to improve the driving system efficiency through reducing the valve throttle loss. The other is to recover and reutilize the lost gravitational potential energy.

Can ultracapacitors protect EV battery pack?

In order to address these challenges, researchers , have employed energy management control strategies for hybrid energy storage systems (HESS) in EV powertrain topologies, using ultracapacitors to operate as power peak buffer systems, protecting battery pack and extending its lifespan.

What type of driving system is used in a heavy-duty manipulator?

An EMA and a hydraulic cylinder-hydraulic accumulator combination are used to drive the manipulator together. Furthermore, electrically active and hydraulically passive driving systems are employed based on the operational characteristics of the heavy-duty manipulator.

Why is EMA difficult to drive a heavy-duty manipulator independently?

However, due to the low power density ratio, the EMA is difficult to drive the heavy-duty manipulator independently. For the energy recovery mode, the hydraulic mode has less energy conversion links than the electrical mode.
