Anticipated growth of sub-sea technologies for security, infrastructure inspection, and exploration, motivates a deeper understanding of dynamics of underwater navigation in proximity to a submerged target surface. In this paper we discuss the phenomenon of a smooth, submersible micro robot with a single bottom jet that enables hovering and sliding over underwater surfaces. Such motion has applications...
A pair of mobile robots acting on opposite sides of a thin plate is developed for a class of tasks where robots have to work together, carrying a pair of end-effectors and traversing across a plate surface. Using powerful magnets, the paired robots attract each other, support themselves against gravity, and generate traction force to move across the panel.
We present an initial design of a mobile robotic system for automated assembly inside an aircraft body. This system allows for the positioning control of a heavy duty end effector that is working on the far side of a thin wall at any orientation. It utilizes electromagnets to hold the end effector against the wall, as well as linear motor type actuation for locomotion. Initial testing on a prototype...
