Generating ExpectedTime Efficient Trajectories for Rapidly Finding an Object in Known Environments (2004)In the final version, the robot is no longer a point but a mobile manipulator moving in a 3D environment. The proposed solution builds on previous results and also introduces a samplebased convex cover to estimate the ...
