This paper presents the virtual environment implementation for simulation and design conception of supervision and control systems for mobile robots, that are capable to operate and adapt in different environments and conditions. The purpose of this virtual system is to facilitate the development of embedded architecture systems, emphasizing the implementation of tools that allow the simulation of the kinematic conditions, dynamic and control, with monitoring in real time of all important system points. For this, an open control architecture is proposed, integrating the two main techniques of robotic control implementation in the hardware level: systems microprocessors and reconfigurable hardware devices. The implemented simulator system is composed of a trajectory generating module, a kinematic and dynamic simulator module, and an analysis module of results and errors. All the kinematic and dynamic results obtained during the simulation can be evaluated and visualized in graphs and table formats in the results analysis module, allowing the improvement of the system, minimizing the errors with the necessary adjustments and optimization. For controller implementation in the embedded system, it uses the rapid prototyping which is the technology that allows in set, with the virtual simulation environment, the development of a controller project for mobile robots. The validation and tests had been accomplished with nonholonomic mobile robot models with differential transmission.

Swarming robots basically consist of a group of several simple robots that interact and collaborate with each other to achieve shared goals. A single robot system is not suitable to be used as an agent for the navigation usually covers a wide range of area. Therefore, a group of simple robots is introduced. A group of robots can perform their tasks together in a more efficient way compared to a single robot; hence develop a more robust system. In order to interact, a wireless communication strategy is implemented to enable the group of mobile robots to perform their tasks. This project implements the swarming algorithm by supplementing the ability of mobile robot platforms with autonomy and odour detection. The work focused on the localization of chemical odour source in the testing environment and the leader and follower swarm formation through wireless communication. To enable the mobile robots to communicate with each other and able to perform leader and follower designation once the target has been found, the RSSI value of X-Bee module is used.

The localization of mobile robots is one of important problems for navigation of mobile robots. The wireless sensor network, i.e., Cricket wireless localization technology, was used to obtain motive condition of mobile objects in this study. The information transmission between the Cricket localization system and mobile robot system was achieved for localization, navigation and control of the mobile object. The errors of localization sampling data of the Cricket localization system vary within 3cm in a static condition. The Cricket localization system can meet the navigation requirement of the mobile robots.

Projek ini mengeksplotasi penggunaan Teknologi Bluetooth dalam robot mudah alih. Robot mudah alih mempunyai kebolehan untuk bergerak secara automasi menggunakan algoritma yang rumit dan canggih. Algoritma disimpan dalam sebuah komputer sebagai tuan dan juga “server”. Segala bacaan penderia daripada robot mudah alih akan dihantar kepada tuan dan diproses. Kemudian, arahan untuk langkah seterusnya akan dihantar dari “server” kepada robot mudah alih dalam mode komunikasi dua hala dan dupleks penuh. Maka, “otak” utama berada di "server" dan bukannya pada robot mudah alih. Kertas ini akan memfokus pada perantaraan muka antara Bluetooth transceiver dan Handy Board MC68HC11 mikro pengawal pada robot mudah alih. Untuk kes biasa, satu penerima dan penghantar diperlukan untuk setiap alat (server dan client) masing-masing, tetapi dengan Teknologi Bluetooth, hanya dua Bluetooth transceiver diperlukan untuk mencapai perhubungan dupleks penuh. Projek ini telah menghasilkan robot mudah alih dengan kebolehan Bluetooth. Robot tersebut boleh dikawal secara “wirelessly” melalui Bluetooth transceiver. Kata kunci: Teknologi Bluetooth; dua hala; duplex penuh; automasi; Handy Board This work explores the implementation of Bluetooth technology in mobile robots. The mobile robot has the capability to move around autonomously using complicated and powerful algorithm. The algorithms are stored in the master as the server. All sensor readings from the mobile robot will be transmitted to the master and processed. Then, command or instruction for further action is transmitted from the server to the mobile robot in a bi-directional full duplex communication mode. Hence, the main “brain” is in the server instead of the mobile robot. This paper will focus on the interfacing between Bluetooth tranceiver and Handy Board MC68HC11 micro-controller of mobile robot. For common case, a receiver and transmitter are needed for each device (robot and control unit), but with Bluetooth technology, only two Bluetooth transceivers are needed to achieve full duplex connection. This project has provided a Bluetooth enabled mobile robot. The mobile robot can be controled wirelessly via Bluetooth transceiver. Key words: Bluetooth Technology; bi-directional; full duplex; autonomously; Handy Board

Automated mobile platforms are commonly used to provide services for people in an intelligent environment. Data on the physical position of personal electronic devices or mobile robots are important for information services and robotic applications. Therefore, automated mobile robots are required to reconstruct location data in surveillance tasks. This paper describes the development of an autonomous mobile robot to achieve tasks in intelligent environments. In particular, the robot constructed route maps in outdoor environments using laser imaging detection and ranging (LiDAR), and RGB-D sensors via simultaneous localization and mapping. The mobile robot system was developed based on a robot operating system (ROS), reusing existing software. The robot participated in the Nakanoshima Challenge, which is an experimental demonstration test of mobile robots in Osaka, Japan. The results of the experiments and outdoor field tests demonstrate the feasibility of the proposed robot system.

Mobile robots often require distance to objects surrounding them for navigation tasks. The sonar ring is widely used to measure distance because it is easy to use and provides distance information all around the robot. Although accurate in range, a sonar ring has difficulty determining bearings to surrounding objects. Conventional sonar rings are slow in covering a full 360 degrees due to sequential driving of transducers for avoiding interference. In this paper, we propose a new sonar-ring sensor system for a mobile robot that can accurately measure bearing angles to objects in a single measurement. The proposed system simultaneously transmits and receives ultrasound in all directions and measures time-of-flight (TOF) differences, achieving fast, accurate measurement of points reflected around a robot. System design and implementation of the proposed sonar ring are also described and the effectiveness of the proposed system shown by experimental results.
