This paper aims to develop a control algorithm for a unicycle type AGV (Automated Guided Vehicle) to follow a trajectory predefined by a line avoiding oscillation on its movements. At the first tests the PID controller will be applied. On some applications cameras are used to help a robot follow a track (instead of infra red sensors), determining if it should keep a forward movement or turn to any...
This paper proposes a new adaptive repetitive visual-servo control system for a moving high-flying vehicle (HFV) with an uncalibrated camera to monitor, track, and precisely control the movements of a low-flying vehicle (LFV) or mobile ground robot. When deployed, a remote operator of the HFV defines the desired trajectory for the LFV in the HFV's camera frame (image frame). Due to the circulatory...
This paper presents a development algorithm of hemi-cylinder projection plane applied in panorama view of AVM applications. This projection plane is established to maintain the FOV in horizontal axis. The calibration parameters are estimated with OcamCalib toolbox, and comparison of keypoint detection are showed as experimental results. Our panorama view stitching with homography matrix calculated...
Many accidents happen while driving due to false estimation of the tailgating vehicle's distance and even while backing up or parking the vehicles in a parking lot. It is very important for the driver to know how close the tailgating vehicle. It is equally important to know the vicinity of the other vehicles and objects while parking or taking vehicle from the parking lots. The main objective of this...
Consider a single camera mounted on the inside of a vehicle's windscreen used for detecting potholes and other obstacles on the road surface. This paper outlines three approaches to the depth estimation problem of determining the distance to these obstacles in the range of 5 m to 30 m. We provide an empirical evaluation of the accuracy of these approaches under various conditions, and make recommendations...
This paper introduces the method of detecting a route space for an industrial indoor vehicle. The vehicles work in many industrial fields, e.g., a semiconductor production and a car assembly factory. The detection of the route space under illuminant disturbance is an important problem for the industrial vehicle robot. The industrial vehicle has to move to the same areas in a factory. For these works,...
This paper proposes a method to analyse humanmade environments in order to identify ascending steps and stairs and recognize their parameters. The system uses adjustable 3D environment geometries for the detection of steps and estimates tread depth and width, riser height and yaw orientation from the camera to staircase. Those parameters are needed by humanoid robots to ensure a safe traversal of...
Vessel maintenance entails periodic visual inspections of internal and external parts of the hull in order to detect the typical defective situations affecting metallic structures. Nowadays, robots are becoming more and more important regarding these inspection tasks, since they can collect the requested information and, thus, prevent humans from performing tedious, and even dangerous tasks because...
This paper shows how to push an unknown object in the plane from an initial pose to a target pose with two cooperating mobile robots. On the object motion, we deliberately impose non-holonomic velocity constraint with pushing mobile robots. This yields smooth and efficient trajectories. Pushing manipulation is performed, for the first time, with a new uncalibrated image-based control scheme. This...
Sensor coverage of large areas is a problem that occurs in a variety of different environments from terrestrial to aerial to aquatic. Here we consider the aquatic version of the problem. Given a known aquatic environment and collection of aquatic surface vehicles with known kinematic and dynamic constraints, how can a fleet of vehicles be deployed to provide sensor coverage of the surface of the body...
Intelligent robot is a promising research topic for home healthcare, especially for the elderly home healthcare because it can provide the basic life needs via material assistance. However, until now, the design and implementation of an intelligent robot for home healthcare is still a very difficult problem unless we can solve the recognition system problem of a robot, which is usually extremely sensitive...
This paper presents a new set of approaches for teleoperation of remotely operated vehicles (ROVs), or autonomous underwater vehicles (AUVs) with on-board cameras. We address the control allocation problem for underwater vehicles, i.e., how to best distribute the control forces so that the robot behaves as intuitively as possible based on the operator's commands. This calls for intelligent control...
This paper proposes the control design and implementation of an intelligent vehicle combined with robotic manipulator and computer vision. It can be roughly divided into three main directions for the design of intelligent vehicle, including path planning of mobile vehicle, position control of robot arm system and appropriate applications of image recognition. For the consideration of path planning...
The paper presents a method to assist the landing of an Unmanned Aerial Vehicle (UAV) on a moving Unmanned Ground Vehicle (UGV). The measurement of the relative position of the UAV and the UGV is carried out by a cheap USB camera. The paper deals with the list of the difficulties of such a system which have to be taken into account and develop ideas on how to overcome them. The solution of the key...
This paper proposes a new visual controller to endow flying manipulators with the capability of cooperatively and automatically positioning an assembly part on a visual target. We consider two VToL UAVs each equipped with a robot manipulator and a video camera. The two manipulators are rigidly connected to an assembly part, consisting of bar in this case study, that needs to be automatically placed...
We describe the approach of Worcester Polytechnic Institute's (WPI) Robotics Engineering C Squad (WRECS)to the utility vehicle driving task at the Defense Advanced Research Projects Agency (DARPA) Robotics Challenge (DRC) Trials held in December 2013. WRECS was one of only seven teams to attempt the driving task, and the only team with an ATLAS robot to successfully drive the course. We implement...
This paper describes the development and design of vision-based remote controlled cellular robots. Cellular robots have numerous applications in industrial problems where simple inexpensive robots can be used to perform different tasks that involve covering a large working space. These robots are controlled based on the visual input from one or more cameras that monitor the working area. As a result,...
We propose an indirect-vision, video-see-through augmented reality (AR) cockpit that uses telexistence technology to provide an AR enriched, virtually transparent view of the surroundings through monitors instead of windows. Such a virtual view has the potential to enhance driving performance and experience above conventional glass as well as head-up display equipped cockpits by combining AR overlays...
This paper presents a method for vision-based landing of a multirotor unmanned aerial vehicle (UAV) on an autonomous surface vehicle (ASV) equipped with a helipad. The method includes a mechanism for helipad behavioural search when outside the UAV's field of view, a learning saliency-based mechanism for visual tracking the helipad, and a cooperative strategy for the final vision-based landing phase...
To achieve the complete car driving task with a humanoid robot, it is necessary to develop a set of basic action primitives, including: walking to the vehicle, manually controlling its commands (ignition, accelerator and steering), and moving with the whole-body, for car ingress/egress. In this paper, we propose an approach for realizing the central part of the complete task, consisting in driving...
