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 robotic control system implemented to handle tasks, which if performed by humans pose significant risks. The system described is used for manually controlling a six wheel all-terrain vehicle through a radio interface from a safe distance. Dual wireless video channels offer a feedback to the operator for maneuvering and controlling the robot. Developing robotic manipulators...
Autonomous vehicles have attracted considerable attention in the research community and industry due to their potential benefits to unmanned driving and assisted driving. This paper addresses the problem of designing lateral control law and the strategy of determining the giving speed for autonomous vehicles. An improved method of calculating lateral offset and angle error based on multiple look-ahead...
The video shows an overview of the ISRobotCar, an experimental autonomous electric vehicle that integrates the robot operating system (ROS.org) and several sensors such as an IBEO laser scanner, inertial measurement units (IMU), RTK-GPS, vision cameras, and magnet detectors for magnetic guidance. The main purpose of this vehicle is to serve as a platform for experimental testing of algorithms required...
For transportation tasks predominantly wheeled vehicles are used. This is due to a wheel's easy construction, its simple actuation and control implementation as well as the fact that no energy is wasted to overcome gravitational effects. But wheeled vehicles are best suited for a use on prepared terrain and surfaces. Their mobility on unstructured and rough terrain is significantly limited. These...
This paper presents the platform and system architecture of an intelligent vehicle, presenting the control system modules allowing the vehicle to navigate autonomously. Our research group has been developed works on autonomous navigation and driver assistance systems, using CaRINA I platform to experiments and validation. Our platform includes mechanical vehicle adaptations and the development of...
ACC (Adaptive Cruise Control) system has been attracted much attention because it has a potential to reduce traffic accidents and drivers' stress. The system maintains a safe inter-vehicular distance and assists driving by keeping traffic lane automatically. Though the conventional ACC system can observe the preceding vehicles using a millimeter wave radar, it fails in following in case of a curved...
Wireless communication is applied frequently in laser automatic guided vehicle (AGV) communication system, but at present the system usually adopts the wireless static central control mode in which vehicles of AGV system are controlled and managed by a center control unit and cannot communicate with each other. An AGV wireless control system based on wireless sensor network and mobile robots control...
In this paper, we propose a robust multirate controller for steering control of autonomous vehicles. The goal of this research is to fuse the vision processer and motion sensor for the lane keeping and lane change systems. A robust multirate Kalman filter is designed to estimate the vehicle states and lane information at a fast sampling rate. This method provides the robust performance against uncertain...
Force display is an important element to set up a user-friendly man-machine interaction system (e. g. haptic interface system). To display force easily and conveniently by means of a simple mechanism, we focus attention on the static characteristics of an omnidirectional mobile robot. This paper presents development of a prototype of a planar 3-DOF wheeled motion base consisting of omnidirectional...

This paper presents a microcontroller implementation of a fuzzy control algorithm applied to the self-developed AGV platform. The method applies fuzzy control theory to obtain the appropriate velocities of left wheel and right wheel by selecting optimal parameter of fuzzy logic controller. In order to put the fuzzy controller into operation, the run-time inference is reduced to a table look-up which...
Strategies for cautious navigation of robotic wheelchairs are presented. They are based on known navigation environments, which allow generating paths with low risk of collision. A path-following algorithm is then proposed to keep the mobile vehicle close to the reference route, thus minimizing the risk of collision. Although navigation environments are supposedly known, they are not necessarily static...
