A frequent concern among students and teachers working with educational robotics is about the results gathered through practical activities. Currently, educational institutions and robotics competitions lack of mechanisms that can evaluate the robot's behavior during the accomplishment of the proposed challenges. In this work, we propose the development of a technological solution using Computational...
The autonomous vehicle valet parking service (AVP) enables a vehicle to drive and park without any human interaction. The driverless vehicle has to follow the scheduled route and be parked in a parking lot automatically. Most fundamental technologies for autonomous vehicle valet parking service are controlling vehicle driving and parking. For autonomous driving, the path to near goal parking lot has...
This paper describes the development of an emergency obstacle avoidance module for a mobile robot by using a laser range finder. To achieve safe and rapid obstacle avoidance, we apply a subsumption architecture. In the proposed system, the subsumption architecture provides four layers of simple behavior modules such as an emergency obstacle avoidance module and autonomous driving module. Since emergency...
In order to fulfill the mission, the search and rescue system must be able to locate the victims quickly and reliably. Current search and rescue approaches generally rely on either teleportation robots, or teams of wireless robots. The advent of Wireless Sensor Network (WSN) technologies is paving the way for a panoply of new ubiquitous computing applications. We present an approach utilizing Robotic...
Teleoperation is an important strategy for controlling outdoor mobile robots. It determines the reliability and the fields of the mobile robots. This paper introduced a type of teleoperation system for multiple mobile robots. Improved image radio system ensured the image transmission channels of coherent image clarity. Improved new data transmission system ensured that the data transmission is stable...
Hybrid sensor networks consisting of both in-expensive static wireless sensors and highly capable mobile robots have the potential to monitor large environments at a low cost. To do so, an algorithm is needed to assign tasks to mobile robots which minimizes communication among the static sensors in order to extend the lifetime of the network. We present three algorithms to solve this task allocation...
The first Chinese unmanned ground vehicles competition - The 2009 Future Challenge: Intelligent Vehicles and Beyond (FC'09) pushed China's unmanned vehicles out of laboratories and into application environments. In order to further promote the development of unmanned vehicle technologies, the test and evaluation system for unmanned vehicles needs to be studied. The design method of test environment...
In order to monitor the leakage of hazardous chemicals and guarantee the safety of people in hazardous areas, we developed RESRS (Robot Emergency Search and Rescue System). RESRS integrated technologies such as mobile robot and WSN (Wireless Sensor Network). The mobile robots in the system act as mobile nodes of WSN. We describe the components of the generic RESRS's architecture in detail. A small-scale...
CAESRS (Chemical Accident Emergency Search and Rescue System) was developed for the use of monitoring the leakage of hazardous chemicals and guaranteeing the safety of people in hazardous areas. Technologies such as WSN (wireless sensor network) and mobile robot need to be integrated to build up CAESRS. We describe the components of the generic CAESRS's architecture in detail. A small-scale demonstration...
In this paper we introduce our novel concept of sycophant wireless sensors (SWS) which is a static ecto-parasitic clandestine sensor network mounted incognito on a mobile agent using only the agent's mobility without intervention. SWS networks not only communicate with each other through mobile WSN but also cooperate with them to form a global hybrid wireless sensor network (WSN). Our work develops...
As sensor technology advances, the availability of high resolution data and complex sensor readings become more commonplace, and the range of potential sensor network applications, accuracy, and data collection efforts expands. As a result, there is an increased need for tiered sensor network architectures and energy efficient data collection mechanisms in order to maintain network feasibility and...
Effective robotic autonomy requires an accurate estimation of the remaining power that the robot is carrying. There are a number of methods to estimate the remaining capacity of the robot's batteries. The accuracy of these approaches varies depending upon the chemical composition of the batteries as well as the means by which the monitoring is conducted. In this paper, an overview of various battery...
In this paper, we present our autonomous mobile robotic system for surveillance of indoor environments. The robot is equipped with a monocular camera, a laser scanner, encoders, and an RFID device, connected to a multi-layer decision and control scheme. Two main functions are implemented: to build a map of the environment, identifying specific areas of interest, marked by RFID tags; to monitor the...
Multi-robot systems offer many advantages over a single robot system including redundancy, coverage and flexibility. One of the key technical considerations in fielding multi-robot systems for real-world applications is the coordination of the individual units. The cluster space control technique promotes simplified specification and monitoring of the motion of mobile multi-robot systems. Previous...
