Robotics PRESENTED BY Ishani Vyas CS575
What is Robotics • Science and Technology of robots. • Knowledge of electronics, mechanics and software. • Define the Robot • One of the branch of Artificial Intelligence
Definition of Robot • A reprogrammable, multifunctional manipulatordesigned to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks. • Force through Intelligence
Types of Robots • Mobile Robot • What is Mobile Robot ……Machine capable of movement and that can be used to perform any physical tasks. A Machine that senses , thinks and acts. • Application of Mobile Robot -- Military, Security environment & Industry.

Classification of Mobile Robot • According to Environment ---Land or Home Robot ---Aerial Robots called as UAV (Fighter Planes) ---Underwater Robots called as AUV • Device Used to Move ---Human-Like Legs (i.e an Android) ---Humanoid ---Wheeled Robot
Under Water Robot • Travels underwater. It can operate in water as deep as 6000 meter. • Device powered by batteries or fuel cells • 1st AUV was developed in 1970 By MIT • Difference between ROV And AUV
Use of AUV • Oil & Gas Industry uses AUV to make detailed map of the seafloor before start building any sub sea infrastructure. • Scientist • In military mission , Map an area to determine if there are any mines.
Functions of AUV • AUV carry sensor to navigate & map features of the ocean. • Typical Sensor include compasses, depth sensor , side scan …..Sonar …..Magnetometer …..Thermistor ….Conductivity Probs
Many Company Making • Bluefin Robotics • Hafmynd • Hydroid, LLC • International Submarine Engineering, Ltd. - AUVs • Kongsberg Maritime • Ocean Server Technology Inc. • Sias Patterson Inc. • Alaska Native Technologies • Subsea 7
Aqua : An Amphibious Autonomous Robot • Robot that swims via motion of its legs rather than using thrusters and control surface in open water or walk on the bottom of the ocean. • Using variety of sensors to estimate its position with respect to Local visual features and provide a global frame of reference.
Developed by McGill university in collaboration with the university at Michigan, the university of california at berkeley and Carnegie Mellon University.
About the vehicle • Aqua is based on RHex, a terrestrial six-legged robot. • Capabilities –Diving to a depth of 30 meters, Swimming at up to 1.0m/s and Crawling on the bottom of the sea. • Its 65cm Long,45cm Wide and 13cm high& it has aluminum waterproof shell &displaces about 16 kg of water. • About batteries provide more than threehours of continuous operation.
Works based on this Function • Visual Behavior Control • Sensor • Sensing for Environmental Recovery &Pose Maintenance • Acoustic Vehicle Localization • Robot Localization and Mapping
