Design of Intelligent Robots Based on Body Sense Control

Recognizing human actions to control the robot has become a challenging task. This paper provides a manipulator control system based on a mobile platform. The bending Angle of the specific connecting rod mechanism is collected to obtain the bending degree of the finger. The nine-axis gyroscope is used to detect the attitudes of the hand and the arm, and the data is transmitted to the HT32F5352 control board. Experimental results show that intelligent robots based on motion sensing can be equipped with automatic and manual control, environmental detection, and other functions.

Coplanar integration of antipodal vivaldi antenna with metasurface antennas for ground penetrating radar and 5–GHz WIFI applications

In this paper, we design a novel antenna with dual-band and multi-radiation modes by integrating the two metasurface binary array antennas (MBAAs) into the antipodal Vivaldi antenna (AVA). Metasurface binary array antenna 1 (MBAA-1) and metasurface binary array antenna 2 (MBAA-2) are symmetrically embedded on two radiation patches of AVA. When AVA is excited, vertical down radiation can be achieved. When MBAA-1 or MBAA-2 is excited, horizontal forward or backward radiation can be achieved. The simulated results show that AVA and MBAAs have the −10 dB return loss bandwidths of 163.6% and 9.3% and the realized gain of 5.5–8.1 dBi and 8.0–10.0 dBi cover the Ground Penetrating Radar (GPR) band (0.6–6.0 GHz) and the 5–GHz WIFI band (4.9–5.9 GHz), respectively. The test results are in good agreement with the simulated results. The proposed antenna realizes the integrated design of 5–GHz WIFI and GPR antennas, which can be applied to the antenna system design of intelligent robots and UAVs, and contribute to the integration development of wireless communication and radar in the future.

Research on the evaluation method of agricultural intelligent robot design solutions.

At present, agricultural robots are produced in large quantities and used in agricultural planting, and the traditional agricultural model is gradually shifting to rely on the Internet of Things and sensors to accurately detect crop growth information. The scientific and rational design of agricultural robots plays a huge role in planting and production efficiency, however, the factors affecting their design are complex and ambiguous, so it is necessary to use a rational evaluation system to make a preferential decision among multiple design options. In order to reduce the subjectivity and blindness of program selection in the process of agricultural robot design, make the decision more objective and reasonable, and thus enhance the practicality and scientificity of the program, a new comprehensive evaluation method based on user requirements is proposed. First, after researching and interviewing users and farming operations, obtaining raw information on requirements, using the Kano model to classify the requirements and establishing an evaluation index system. Secondly, the combination of hierarchical analysis(AHP) and entropy weighting method is used to assign weights to the evaluation index system, calculate the weight value and importance ranking of each index, and carry out various program designs based on the ranking. Finally, the VIKOR method was applied to evaluate and rank the design solutions. The new evaluation method can better complete the preferential decision of the agricultural robot design scheme and get a more perfect design scheme, which reduces the influence of human subjective thinking in the decision-making process. The method not only corrects the traditional evaluation method, but also effectively improves the accuracy and comprehensiveness of the design evaluation process. It also provides a reference for designers to preferably select design solutions and promotes the development of small mobile machines in the context of smart agriculture.

Design Scheme of Intelligent Robot Based on Crawler Sports Chassis

The chassis structure design of mobile robots is currently separated into four categories: wheel type, mechanical leg type, McNair wheel type, compound type, and crawler type, with wheel leg type, common crawler type, and wheel crawler type being under compound type. A formula Complex application scenarios frequently limit the robot's passibility throughout the actual application process. A new robot design plan is offered to overcome this problem: an intelligent robot built on a crawler-type moving chassis. To achieve the robot's astute observation of the surrounding environment, the advantages of wheeled and legged robots will be organically merged, and intelligent control terminals will be included in the hardware design. The mechanical framework will be built on a traditional crawler chassis, with leg guiding added. The crawler actuator of the structure will drive the crawler actuator of the leg-guided design to enable the robot to get out of problems in the face of challenging terrain conditions such as stairs, steps, and steep slopes. This work proposes an intelligent robot design strategy based on crawler motion chassis with high practicability, novelty, and broad applicability.

The Role of Physics-Based Simulators in Robotics

Physics-based simulation provides an accelerated and safe avenue for developing, verifying, and testing robotic control algorithms and prototype designs. In the quest to leverage machine learning for developing AI-enabled robots, physics-based simulation can generate a wealth of labeled training data in a short amount of time. Physics-based simulation also creates an ideal proving ground for developing intelligent robots that can both learn from their mistakes and be verifiable. This article provides an overview of the use of simulation in robotics, emphasizing how robots (with sensing and actuation components), the environment they operate in, and the humans they interact with are simulated in practice. It concludes with an overview of existing tools for simulation in robotics and a short discussion of aspects that limit the role that simulation plays today in intelligent robot design.

The design of an intelligent soccer-playing robot

Purpose – The purpose of this paper is to design intelligent robots operating in such dynamic environments like the RoboCup Middle-Size League (MSL). In the RoboCup MSL, two teams of five autonomous robots play on an 18- × 12-m field. Equipped with sensors and on-board computers, each robot should be able to perceive the environment, make decision and control itself to play the soccer game autonomously. Design/methodology/approach – This paper presents the design of our soccer robots, participating in RoboCup MSL. The mechanical platform, electrical architecture and software framework are discussed separately. The mechanical platform is designed modularly, so easy maintainability is achieved; the electronic architecture is built on industrial standards using PC-based control technique, which results in high robustness and reliability during the intensive and fierce MSL games; the software is developed upon the open-source Robot Operating System (ROS); thus, the advantages of ROS such as modularity, portability and expansibility are inherited. Findings – Based on this paper and the open-source hardware and software, the MSL robots can be re-developed easily to participate in the RoboCup MSL. The robots can also be used in other research and education fields, especially for multi-robot systems and distributed artificial intelligence. Furthermore, the main designing ideas proposed in the paper, i.e. using a modular mechanical structure, an industrial electronic system and ROS-based software, provide a common solution for designing general intelligent robots. Originality/value – The methodology of the intelligent robot design for highly competitive and dynamic RoboCup MSL environments is proposed.

Localization of sound sources in reverberant fields is significant for the research areas such as noise sources recognition, meeting speaker tracking system, intelligent robot design. Microphone arrays are usually used, however, in most applications in rooms it is practical and economical to decrease the microphones. In this paper, using only one microphone a virtual time reversal algorithm based on the ray-tracing method has been developed according to the reciprocity theorem and the time reversal invariance of linear wave equation. The algorithm has been validated by the localization experiments in a real room and a virtual room. Then the performance of the algorithm under the conditions of various reverberation time, source-receiver distance and sound reflection times has been investigated according to a specified ratio.

Robotics in the new millennium: entering the age of exploitation

Robotics began in the 1960s as a field studying a new type of universal machine implemented with a computer-controlled mechanism. This period represented an age of overexpectation, which inevitably led to frustration and discontent with what could realistically be achieved given the technological capabilities at that time. In the 1980s, the field entered an era of realism as engineers grappled with these limitations and reconciled themwith earlier expectations. Only in the past few years havewe achieved a state in which we can feasibly implement many of those early expectations. As we do so, we enter the ‘age of exploitation.’1 For more than 25 years, progress in concepts and applications of robots have been described, discussed, and debated. Most recently we saw the development of ‘intelligent’ robots, or robots designed and programmed to perform intricate, complex tasks that require the use of adaptive sensors. Before we describe some of these adaptations, we ought to admit that some confusion exists about what intelligent robots are and what they can do. This uncertainty traces back to those early overexpectations, when our ideas about robots were fostered by science fiction or by our reflections in the mirror. We owe much to their influence on the field of robotics. After all, it is no coincidence that the submarines or airplanes described by Jules Verne and Leonardo da Vinci now exist. Our ideas have origins, and the imaginations of fiction writers always ignite the minds of scientists young and old, continually inspiring invention. This, in turn, inspires exploitation. We use this term in a positive manner, referring to the act of maximizing the number of applications for, and usefulness of inventions. Years of patient and realistic development have tempered our definition of intelligent robots. We now view them as mechanisms that may or may not look like us but can perform tasks as well as or better than humans, in that they sense and adapt to changing requirements in their environments or related to their Figure 1. Conceptual framework of components for intelligent robot design.

BEHAVIOURAL ADAPTATION OF REAL-TIME EMOTIONAL ROBOTIC AGENTS

The interest of the application of emotional computational models to improve the design of intelligent robots has been growing in the roboticist community for the last years. Emotional models are used to modulate the robot cognitive system to improve its ongoing behaviour control. A key issue of the design is the selection and modulation of the cognitive behavioural load depending on the problem to be solved. To undertake the modulation, the agent is conscious of its mental capacities and it manages emotional appraisals that are dependent on the agent attitude, such as the expectation of success. This paper presents the modulation system of real-time emotional agents (RTEA) and shows how emotional appraisals, that have proven effectively in ethological systems, can influence the agent's decision making.

One-Chip Solution to Intelligent Robot Control: Implementing Hexapod Subsumption Architecture Using a Contemporary Microprocessor

This paper introduces a six-legged autonomous robot managed by a single controller and a software core modeled on subsumption architecture. We begin by discussing the features and capabilities of IsoPod, a new processor for robotics which has enabled a streamlined implementation of our project. We argue that this processor offers a unique set of hardware and software features, making it a practical development platform for robotics in general and for subsumption-based control architectures in particular. Next, we summarize original ideas on subsumption architecture implementation for a six-legged robot, as presented by its inventor Rodney Brooks in 1980's. A comparison is then made to a more recent example of a hexapod control architecture based on subsumption. The merits of both systems are analyzed and a new subsumption architecture layout is formulated as a response. We conclude with some remarks regarding the development of this project as a hint at new potentials for intelligent robot design, opened up by a recent development in embedded controller market.
