This paper is an overview of the AVENUE project at Columbia University. AVENUE's main goal is to automate the site modeling process in urban environments. The rst component of AVENUE is a 3-D modeling system which constructs complete 3-D geometric models with photometric texture mapping acquired from di erent viewpoints. The second component is a planning(More)
We present a microrobotic system for protein crystal micromanipulation tasks. The focus in this paper is on the task known to crystallographers as streak seeding – it is used to entice certain protein crystals to grow. Our system features a set of custom designed micropositioner end-effectors we call microshovels to replace traditional tools used by(More)
In this talk I will focus on the use of a mobile robot for autonomous exploration of an initially unknown environment. Here, by “exploration” I mean a task whose final or intermediate result is a model of this environment. I will consider the following aspects: • mobile robot sensors for environmental modeling • types of explored environments • types and(More)
