Migration of sand dunes is accounted as one of the most important natural disasters in arid and desert regions. In this study, high resolution images are combined with field measurements in order to quantitatively study the migration and long term changes in the shape and morphology of barchans. The results indicated a power correlation between height and width of barchans (R 2 ≈0.93). It...
This video shows an uncut sequence of a 15 module robot in a bi-pedal configuration subject to a variety of disturbances yet staying on task. As the robot walks, a large disturbance is introduced. A human kicks the robot in its midsection causing the robot to fall into three separate clusters of five modules. Each of these pieces diagnose their state sensing gravity and their connectedness. They each...
This paper introduces a new challenge problem: designing robotic systems to recover after disassembly from high-energy events and a first implemented solution of a simplified problem. It uses vision-based localization for self- reassembly. The control architecture for the various states of the robot, from fully-assembled to the modes for sequential docking, are explained and inter-module communication...
In order to realize the goal of self assembling or self reconfiguring modular robots the constituent modules in the system need to be able to gauge their position and orientation with respect to each other. This paper describes an approach to solving this localization problem by equipping each of the modules in the ensemble with a smart camera system. The paper describes one implementation of this...
