in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...

In this paper, a 3D localization method for an indoor flying robot using an Ultrasonic Positioning System (UPS) is described. The high performance localization systems for an indoor flying robot have high-end prices. Therefore, the main objective of this study was to develop a low cost and high performance indoor localization system. In the localization method, the pseudoranges are measured fro...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

Aerial–aquatic robots have promising applications due to their ability operate in air and water with different motion modes. However, challenges such as water/air transition multimedia movement still limit development. Inspired by the aerial–aquatic behavior of wild ducks, an robot tunable tilting motors a delta wing is introduced. The can perform multimode motion, including flying air, swimmin...

An extensive experimental investigation to study the flow structure over the wing of a fighter type configuration model has been conducted. The model used for this study was similar to the High Alpha Research Vehicle (HARV) that has been used in various European research centers for studying its force and moment characteristics. Tests were conducted at two subsonic speeds and at low to moderate...

Flies are among the most agile flying creatures on Earth. To mimic this aerial prowess in a similarly sized robot requires tiny, high-efficiency mechanical components that pose miniaturization challenges governed by force-scaling laws, suggesting unconventional solutions for propulsion, actuation, and manufacturing. To this end, we developed high-power-density piezoelectric flight muscles and a...
