In this paper, we consider the design and control of an energy saving robot utilizing springs and reaction wheels. Firstly, we refer to the simultaneous optimization problem of spring parameters and trajectories with respect to the energy consumption based on optimal control theory. In particular, we report on the practical design problem to realize the proposed energy saving manipulator concept. In order to verify the proposed method, a prototype 2DOF manipulator is developed by using linear springs and reaction wheels for actuation. The experimental results show the effectiveness of the proposed energy saving manipulator concept.

“…However, the recuperative energy is rarely fed back to a network or stored locally due to AC network quality conservation issues or increased costs of the storage systems. Previous research shows impressive energy savings using an increased capacitive energy buffer on a drive's DC bus [1].…”

This paper proposes a new type of power converter for drive systems to enable the exchange of recuperated energy within an independent DC subgrid having one centralized energy storage element.Many industrial applications that require rapid cyclic starts and stops are subject to significant energy waste at the brake chopper of the DC bus due to over voltage during motor deceleration. The proposed solution allows the brake chopper to be eliminated and the otherwise wasted energy to be stored externally. The solution does not require identical hardware or exact synchronization between the drive rectifiers. Experimental results in industrial robotics show savings of up to 20%.

“…Either a single centralized or multiple decentralized energy buffers and rectifiers are to be chosen, as well as the proper line and the type of storing buffer (e.g., capacitor, flywheel, or pneumatic). In [29], the single capacitor energy buffer approach and EnergyTeam (i.e., a multi-star DC-bus connection of several industrial controllers with their own rectifier module) are analyzed and compared in terms of cost efficiency. The addition and installation of capacitor banks is relatively simple but is not so economical.…”

“…The main idea behind these devices is to harvest the energy during the braking phase-which is usually wasted-store it, and provide it back to the system when necessary [20][21][22][23][24][25][26][27][28][29][30][31][32]. Two different types are considered and analyzed: (1) the type of energy-storing devices used, and (2) energy-sharing via the interaction between actuators exchanging energy in a multi-actuator system.…”

A Review on Energy-Saving Optimization Methods for Robotic and Automatic Systems

Abstract:In the last decades, increasing energy prices and growing environmental awareness have driven engineers and scientists to find new solutions for reducing energy consumption in manufacturing. Although many processes of a high energy consumption (e.g., chemical, heating, etc.) are considered to have reached high levels of efficiency, this is not the case for many other industrial manufacturing activities. Indeed, this is the case for robotic and automatic systems, for which, in the past, the minimization of energy demand was not considered a design objective. The proper design and operation of industrial robots and automation systems represent a great opportunity for reducing energy consumption in the industry, for example, by the substitution with more efficient systems and the energy optimization of operation. This review paper classifies and analyses several methodologies and technologies that have been developed with the aim of providing a reference of existing methods, techniques and technologies for enhancing the energy performance of industrial robotic and mechatronic systems. Hardware and software methods, including several subcategories, are considered and compared, and emerging ideas and possible future perspectives are discussed.
