The impressive results of the 2007 DARPA Urban Challenge showed that fully autonomous vehicles are technologically feasible with current intelligent vehicle hardware. It is natural to ask how current transportation infrastructure can be improved when most vehicles are driven autonomously in the future. Dresner and Stone proposed a new intersection control mechanism called Autonomous Intersectio...
The DARPA Urban Challenge required robotic vehicles to travel more than 90 km through an urban environment without human intervention and included situations such as stop intersections, traffic merges, parking, and roadblocks. Team VictorTango separated the problem into three parts: base vehicle, perception, and planning. A Ford Escape outfitted with a custom drive-by-wire system and computers ...
Analysis of the transcriptome of the kleptoplastic sea slug, Elysia chlorotica, has revealed the presence of at least 101 chloroplast-encoded gene sequences and 111 transcripts matching 52 nuclear-encoded genes from the chloroplast donor, Vaucheria litorea. These data clearly show that the symbiotic chloroplasts are translationally active and, of even more interest, that a variety of functional...
Sacoglossan sea slugs are the only metazoans known to perform functional kleptoplasty, the sequestration and retention of functional chloroplasts within their digestive gland cells. Remarkably, a few species with this ability can survive starvation periods of 3-12 months likely due to their stolen chloroplasts. There are no reports of kleptoplast transfer from mother slug to either eggs or juve...
The Defense Advanced Research Project Agency’s (DARPA) Urban Challenge, a contest that pitted robots against each other for 6 h without human intervention, was aimed at advancing the state-of-the-art in research for perception, planning, sensors, and situational awareness with the goal of military application. The event was a success, gaining national media attention for DARPA and robotics; but...
This paper presents a vision-based color segmentation algorithm suitable for urban environments that separates an image into areas of drivable and non-drivable terrain. Assuming that a part of the image is known to be drivable terrain, other parts of the image are classified by comparing the Euclidean distance of each pixel’s color to the mean colors of the drivable area in real-time. Moving th...
Twelve species of Dibrachys Förster are studied from China, of which four new species, Dibrachys golmudica Jiao & Xiao, sp. n., Dibrachys kunmingica Jiao & Xiao, sp. n., Dibrachys liaoi Jiao & Xiao, sp. n. and Dibrachys qinghaiensis Jiao & Xiao, sp. n., and four newly recorded species, Dibrachys braconidis (Ferrière & Faure), Dibrachys confusus (Girault), Dibrachys hians Bouček and Dibrachys ma...
This paper describes a data set collected by MIT’s autonomous vehicle Talos during the 2007 DARPA Urban Challenge. Data from a high precision navigation system, 5 cameras, 12 SICK planar laser range scanners, and a Velodyne high density laser range scanner were synchronized and logged to disk for 90km of travel. In addition to documenting a number of large loop closures useful for developing ma...
[1] The San Andreas Fault (SAF) is the transform boundary between the Pacific and the North American plates, yet up to 25% of the relative plate motion is now accommodated by the eastern California shear zone (ECSZ). Here we investigate the inception of the ECSZ and its geodynamic interactions with the SAF using a 3‐D viscoelastoplastic finite element model. For a given fault configuration of t...
We present an approach that allows mission and contingency management to be achieved in a distributed and dynamic manner without any central control over multiple software modules. This approach comprises two key elements—a mission management subsystem and a Canonical Software Architecture (CSA) for a planning subsystem. The mission management subsystem works in conjunction with the planning su...
