Cartographie et localisation simultanéesvignette|Une carte générée par le robot Darmstadt. La localisation et cartographie simultanées, connue en anglais sous le nom de SLAM (simultaneous localization and mapping) ou CML (concurrent mapping and localization), consiste, pour un robot ou véhicule autonome, à simultanément construire ou améliorer une carte de son environnement et de s’y localiser. La plupart des robots industriels sont fixes et effectuent des tâches dans un environnement connu.
Robot navigationRobot localization denotes the robot's ability to establish its own position and orientation within the frame of reference. Path planning is effectively an extension of localisation, in that it requires the determination of the robot's current position and a position of a goal location, both within the same frame of reference or coordinates. Map building can be in the shape of a metric map or any notation describing locations in the robot frame of reference. For any mobile device, the ability to navigate in its environment is important.
Théorie de l'estimationEn statistique, la théorie de l'estimation s'intéresse à l'estimation de paramètres à partir de données empiriques mesurées ayant une composante aléatoire. Les paramètres décrivent un phénomène physique sous-jacent tel que sa valeur affecte la distribution des données mesurées. Un estimateur essaie d'approcher les paramètres inconnus à partir des mesures.
Interaction homme-robotLes interactions humain-robot (Human-Robot Interactions en anglais, ) sont le sujet d'un champ de recherches ayant émergé du contact et de la rencontre entre l'humain et les systèmes robotiques. Il s'agit d'un champ de recherches interdisciplinaires à la frontière entre la robotique, l'ergonomie et la psychologie. Formé par l’assemblage des deux mots « inter » et « action », le terme d’interaction, dans son étymologie même, suggère l’idée d’une action mutuelle, en réciprocité, de plusieurs éléments.
Robotic sensingRobotic sensing is a subarea of robotics science intended to provide sensing capabilities to robots. Robotic sensing provides robots with the ability to sense their environments and is typically used as feedback to enable robots to adjust their behavior based on sensed input. Robot sensing includes the ability to see, touch, hear and move and associated algorithms to process and make use of environmental feedback and sensory data.
ParameterA parameter (), generally, is any characteristic that can help in defining or classifying a particular system (meaning an event, project, object, situation, etc.). That is, a parameter is an element of a system that is useful, or critical, when identifying the system, or when evaluating its performance, status, condition, etc. Parameter has more specific meanings within various disciplines, including mathematics, computer programming, engineering, statistics, logic, linguistics, and electronic musical composition.
Estimating equationsIn statistics, the method of estimating equations is a way of specifying how the parameters of a statistical model should be estimated. This can be thought of as a generalisation of many classical methods—the method of moments, least squares, and maximum likelihood—as well as some recent methods like M-estimators. The basis of the method is to have, or to find, a set of simultaneous equations involving both the sample data and the unknown model parameters which are to be solved in order to define the estimates of the parameters.
Visual odometryIn robotics and computer vision, visual odometry is the process of determining the position and orientation of a robot by analyzing the associated camera images. It has been used in a wide variety of robotic applications, such as on the Mars Exploration Rovers. In navigation, odometry is the use of data from the movement of actuators to estimate change in position over time through devices such as rotary encoders to measure wheel rotations.
Bras manipulateurvignette|Bras manipulateur d'un robot industriel Kuka en 2003. Un bras manipulateur est le bras d'un robot généralement programmable, avec des fonctions similaires à un bras humain. Les liens de ce manipulateur sont reliés par des axes permettant, soit de mouvement de rotation (comme dans un robot articulé) et/ou de translation (linéaire) de déplacement. Dans le cas d'une imitation complète d'un bras humain, un bras manipulateur a donc de rotation et de translation sur son élément terminal.
Legged robotLegged robots are a type of mobile robot which use articulated limbs, such as leg mechanisms, to provide locomotion. They are more versatile than wheeled robots and can traverse many different terrains, though these advantages require increased complexity and power consumption. Legged robots often imitate legged animals, such as humans or insects, in an example of biomimicry. Legged robots, or walking machines, are designed for locomotion on rough terrain and require control of leg actuators to maintain balance, sensors to determine foot placement and planning algorithms to determine the direction and speed of movement.
