The ability to perform different tasks by a serial manipulator mounted on legged robots, increases the capabilities of the robot. The position/force control problem of such a robot in the stance phase with point contacts on the ground is investigated here. A target plane with known stiffness is specified in the workspace. Active joints of the legs and serial manipulator are used to exert the de...
A mobile robot intercepts a target identified in the image plane of a fixed camera without prior knowledge of camera viewpoint or geometry. The target may be identified manually or autonomously. When the robot moves within the camera image plane, the system develops a table of mappings between the image plane and the ground plane in which the robot moves. The robot is identified in the image pl...
Leg compliance, gravity and ground have a significant impact on the performance and gait characteristics of a quadruped robot. This paper presents results obtained using a planar lumped parameter model of a quadruped robot and an extensive research scheme to determine optimum design parameters for a quadruped moving in different gravity environments. Hildebrand diagrams are used to classify qua...
We consider the problem of robots following natural language commands through previously unknown outdoor environments. A robot receives commands in natural language, such as “Navigate around the building to the car left of the fire hydrant and near the tree.” The robot needs first to classify its surrounding objects into categories, using images obtained from its sensors. The result of this cla...
Lacking a common ground in Human-Robot Interaction is the main source of errors and miscommunications especially for remote exploration robotics. Advances in language and social psychology studies are the rescue, particularly the common ground theory. This paper reviews common ground theory, then it introduces a framework inspired by the miraculous history of Helen Keller. Then a case study is ...
In this paper we describe a new approach to make use of a heterogeneous robot team for the RoboCup Rescue League Virtual Robot competition. We will demonstrate coordinated action between a flying and a ground robot. The flying robot is used for fast exploration and allows the operator to find the places where victims are present in the environment. Due to the fast aggregation of the location er...
This article presents a project that aims at constructing a biologically inspired amphibious snake-like robot. The robot is designed to be capable of anguilliform swimming like sea-snakes and lampreys in water and lateral undulatory locomotion like a snake on ground. Both the structure and the controller of the robot are inspired by elongate vertebrates. In particular, the locomotion of the rob...
The great interest in cultural heritage reflects a person's desire to know and understandtheir origins achievements. However, archaeological sites, like the natural environment, arefinite non-renewable resources. Of all types of under threat, sites andtheir wealth information artifacts are most threatened. In current practice, options forthe preservation include reconstruction, reassembly (anas...
Heterogeneous robot groups are a promising research direction for automating diverse tasks. A functional diierence between individual robot capabilities is likely to allow task-based specialization within the group. We report on experiments with a mechanically heterogeneous robot group consisting of a robotic helicopter and multiple wheeled ground robots. We present a behavior-based control sys...
An easy way to let a robot execute complex actions is to let the robot copy human moves. Useful information are read by sensors and elaborated to convert them into robot movements. This work focuses on keeping the robot balanced while it is performing an action: grasp an object laying on the ground in front of the robot. Experiments are performed with a human user moving in front of the sensor ...
