Withthe development of intelligent manufacturing and the popularization of industrial robots (IR), the energy consumption (EC) of IR become increasingly significant and attract attention from academia and industry. Accurate EC modeling and prediction is the premise and basis for energy efficiency optimization of IR. In recent years, intelligent algorithms like neural networks have been introduced into the EC modeling of IR, and high-precision models can be constructed without complex modeling and parameter identification process. In contrast withthe direct modeling method based on mechanism model, data-driven modeling has significant efficiency and application advantages. In this paper, we propose a ResNet-based IR power modeling method. the deep learning algorithm is used to establish the precise mapping between the operating parameters and power of the industrial robot. then, the model is applied to another industrial robot by transfer learning, which realizes the rapid construction and deployment of power models for different IR. the experimental results show that the proposed IR power modeling method can accurately construct the power model and achieve 21.83% less error. After transfer learning, the power model can be accurately constructed even when the amount of data is reduced by 80%, which facilitates the large-scale practical application of IR and their energy efficiency improvement.

this paper provides a general description of the steps followed to construct an automated Voice Picking Robot. the proposed unit can avoid obstacles, identify objects picking and placing them at their right location. the model is equipped with wireless connectivity to allow its remote control, and it features four wheels and 45-degree rollers. the robot materials are aluminum plates, Polylactic Acid plastic, six NEMA 17 stepper motors, and the ATmega3287P microcontroller. Testing conducted on the robot functioning demonstrates that it behaves as expected and that it can become a useful technological aid in a variety of logistics, industrial, or manufacturing processes.

Over the past few years, soft continuum manipulators gained popularity in advanced robotic systems due to its compliance and ability to execute different complicated tasks in an unstructured environment that are not possible with hard manipulators. In this field of soft robotics, series of experiments and revisions are usually performed first to come up with a nearly perfect hardware prototype. Only after these validations will simulations and kinematic modeling be performed. Recent advancement in the research field includes simulation using the combination of finite element analysis and a mathematical soft-ware for performing numerical iterations. this paper presents a kinematic modeling of a single link constant curvature continuum manipulator based on finite element analysis. the approach aims to demonstrate the capability of finite element analysis to do a "specific" modeling of soft continuum manipulator, i.e., pressure and actuator's length relationship. the result allows us to do complete simulation and modeling of forward and inverse kinematics even if a hardware prototype has not been constructed yet.

this paper analyzes the comfort of wheelchair users when a sliding-mode trajectory-tracking controller is used. the transmission of the horizontal (fore-and-aft) vibration to the head-neck complex (HNC) in the seated human body may cause unacceptable discomfort and motion sickness. A double-inverted pendulum model with two degrees of freedom is considered as a model for the HNC. the user comfort is examined not only in the time domain (using the fourth power vibration dose value), but also in the frequency domain (using the cross-spectral density method). For measuring the acceleration of the wheelchair, along the trajectory, an inertial measurement unit was used.
