The USF team in the 2000 AAAI Mobile Robot Competition had the most extensive experience with the NIST Standard Test Bed for USAR. Based on those experiences, the team reports on the utility of the test bed, and makes over 20 specific recommendations on both scoring competitions and on future improvements to the test

The vertical sorting of grains that occurs during the process of sheet flow largely has been ignored in parameterized models for sediment transport. Here we performed computer simulations of sheet flow transport with bimodal distributions of coarse grains under forcing from idealized nearshore waves. The results demonstrate that the mobile bed rapidly experiences vertically segregation of grain...

We present a robotic system designed to provide physical assistance to a person in bed. The system consists of a robotic bed (Autobed) and a mobile manipulator (PR2) that work together. The 3 degree-of-freedom (DoF) robotic bed moves the person’s body and uses a pressure sensing mat to estimate the body’s position. The mobile manipulator positions itself with respect to the bed and compliantly ...

An onboard vehicle-to-vehicle multi-hop wireless networking system has been developed to test the realworld performance of telematics applications. The system targets emergency and safety messaging, traffic updates, audio/video streaming and commercial announcements. The test-bed includes a Differential GPS receiver, an IEEE 802.11a radio card modified to emulate the DSRC standard, a 1xRTT cell...

Groin type and vegetation in groin fields directly affect flow field, bank protection, river evolution. Many studies focus on fixed-bed contexts, but there are few the influence of riverbed changes hydrodynamic characteristics around groins. In this study, three types groins investigated experimentally fixed mobile beds terms time-averaged characteristics, turbulence bed changes. both fixed- mo...

-This paper describes the development and testing of a new evolutionary robotics research test bed. The test bed consists of a colony of small computationally powerful mobile robots that use evolved neural network controllers and vision based sensors to generate team gameplaying behaviors. The vision based sensors function by converting video images into range and object color data. Large evolv...

Recently, WSNs (Wireless Sensor Networks) with mobile robot is a growing technology that offer efficient communication services for anytime and anywhere applications. However, the tiny sensor node has very limited network resources due to its low battery power, low data rate, node mobility, and channel interference constraint between neighbors. Thus, in this paper, we proposed a tree based self...
