This paper reports on a transformable sheet type robot that can be thrown from the air. Since sheet type robots can change their own shape and perform tasks according to the situation, they are expected to play an active role in situations with many restrictions, such as disaster-stricken areas. However, since most sheet type robots jump or crawl on the ground, the only way to deliver them to the site of a disaster is to transport them by vehicle or transporter. This research aims to develop a device that can be dispersed from the sky and perform activities on the ground after landing....
This paper describes a control strategy for a linkage finger exoskeleton mechanism with two degrees of freedom. To characterise the performance of the proposed finger motion assistance device, a replica of a human finger is prototyped to mimic human finger motion and to the testing effect of assistance provided by the novel exoskeleton with results from grasp tests. A feasible control design is developed to achieve a robust grasp of an object using the proposed exoskeleton mechanism, which is validated with simulated and experimental results that show how the proposed control algorithm maintains the force within 3% of the desired value. The aim of the paper is to present a control design for the ExoFinger exoskeleton with low-cost easy operation features that are aligned with the similar characteristics of the mechanical design....
In order to improve the effect of engineering safety management, this paper combines intelligent monitoring technology to construct a monitoring robot system. Moreover, this paper analyzes the characteristics of the digital impulse signal and analyzes the least square filtering and infinite impulse response filtering. At the same time, this paper detects the sample material on the detection test platform, obtains the digital pulse signal, and selects different filtering algorithms and filtering parameters. In addition, this paper uses a signal analysis and processing platform to establish a gamma energy spectrum and analyze the resolution of hydrogen peaks in the gamma energy spectrum. Finally, this paper compares and verifies the filtering algorithms and constructs an engineering safety management system based on robot intelligent monitoring. From the simulation monitoring test results, it can be seen that the engineering safety management system based on robot intelligent detection proposed in this paper has a good effect....
The application of robots reduces repetitive and dangerous tasks for humans, especially the spraying robot, because many spraying materials are corrosive, toxic, and harmful. This paper designs the motion trajectory planning of the material spraying service robot. With the increasing demand for technology, there are strict requirements for the uniformity and thickness of spraying. In view of this, this paper proposes an algorithm for modeling kinematics using a joint screw and optimizes the modeling algorithm using particle swarm optimization. This makes the industrial spraying robot more intelligent and more capable of completing high-standard tasks. The experimental results in this paper show that when the spraying radii on the large-curvature cone surface are 44.5 and 49.5 mm, respectively, the coating distribution in the intersection area of the curved surfaces can be well controlled, and the optimized algorithm can better plan the path of the spraying robot....
The paper describes the semi-automatised calibration procedure of an electronic skin comprising screen-printed graphene-based sensors intended to be used for robotic applications. The variability of sensitivity and load characteristics among sensors makes the practical use of the e-skin extremely difficult. As the number of active elements forming the e-skin increases, this problem becomes more significant. The article describes the calibration procedure of multiple e-skin array sensors whose parameters are not homogeneous. We describe how an industrial robot equipped with a reference force sensor can be used to automatise the e-skin calibration procedure. The proposed methodology facilitates, speeds up, and increases the repeatability of the e-skin calibration. Finally, for the chosen example of a nonhomogeneous sensor matrix, we provide details of the data preprocessing, the sensor modelling process, and a discussion of the obtained results....
