One of the key strategies for improving energy efficiency in robotic systems is the implementation of regenerative braking . Similar to the technology used in electric vehicles, regenerative braking in robots captures the energy typically lost during deceleration and converts it back into electricity. This recovered energy can then be used to power other systems or stored for future use, significantly reducing overall energy consumption.

Advanced motion planning algorithms are also playing a crucial role in enhancing energy efficiency. By optimizing robot trajectories to minimize unnecessary movements and reduce acceleration/deceleration cycles, these algorithms can substantially lower energy usage. Some cutting-edge systems even factor in energy costs when planning paths, choosing routes that balance speed with energy efficiency.

The use of lightweight materials in robot construction is another trend contributing to improved energy efficiency. By reducing the mass that needs to be moved, these lighter robots require less power to operate, leading to lower energy consumption over their lifetime. Additionally, the reduced inertia of lightweight robots allows for faster acceleration and deceleration, potentially improving cycle times without increasing energy usage.

Factories are also exploring the integration of renewable energy sources to power their robotic systems. Solar panels and wind turbines are being installed on factory roofs and grounds, providing clean energy to support robotic operations.
