In practice, surveillance video captured by a small Unmanned Aircraft System (UAS) digital imaging payload is almost always blurred and degraded because of limits of the imaging equipment and less than ideal atmospheric conditions. Small UAS vehicles typically have wingspans of less than four meters and payload carrying capacities of less than 50 kilograms, which results in a high vibration env...

Simske HP Laboratories HPL-2010-8 Payload density, grayscale pre-compensation, authentication The use of 2D color barcodes is quickly becoming commonplace on printed packaging and labels. The color barcode allows for a higher data density in comparison to its 1D or 2D black and...

This paper presents an intervention payload for an AUV working in a valve turning operation in free-floating control mode. The payload consists of a stereo camera for panel detection, a 4 degrees of freedom electrical manipulator and a specifically designed end-effector, which contains a force and torque sensor, an in-hand camera and a passive effector for valve operation. This payload was desi...

In this paper, the tracking control problem is considered for the payload transportation with an underactuated twodimensional overhead crane. Two sliding mode controllers are designed to perform the trajectory tracking. One is proposed to control hoisting and lowering the suspended payload, and the other one is proposed to control both trolley positioning and payload swaying. Considering the se...

In this paper we consider the problem of controlling multiple robots manipulating and transporting a payload in three dimensions via cables. We develop robot configurations that ensure static equilibrium of the payload at a desired pose while respecting constraints on the tension and provide analysis of payload stability for these configurations. We demonstrate our methods on a team of aerial r...
