What is Delaying the Manipulator Revolution?
(MIT Artificial Intelligence Laboratory, 1978-02)
Despite two decades of work on mechanical manipulators and their associated controls, we do not see wide-spread application of these devices to many of the tasks to which they seem so obviously suited. Somehow, a variety ...
Application of Data Flow Computation to the Shaded Image Problem
(MIT Artificial Intelligence Laboratory, 1978-05)
This paper presents a method of producing shaded images of terrain at an extremely fast rate by exploiting parallelism. The architecture of the Data Flow Computer is explained along with an appropriate "program" to compute ...
Hierarchy in Knowledge Representations
(MIT Artificial Intelligence Laboratory, 1977-11)
This paper discusses a number of problems faced in communicating expertise and common sense to a computer, and the approaches taken by several current knowledge representation languages towards solving these problems. The ...
Organic Indoor Location Discovery
(2008-12-30)
We describe an indoor, room-level location discovery method based on spatial variations in "wifi signatures," i.e., MAC addresses and signal strengths of existing wireless access points. The principal novelty of our system ...
A Tour of MOOS-IvP Autonomy Software Modules
(2009-02-13)
This paper provides an overview of the MOOS-IvP autonomy software modules. The MOOS-IvP collection of software, i.e., codebase, described here has been developed and is currently maintained by three organizations - Oxford ...
Self-Stabilizing Message Routing in Mobile ad hoc Networks
(2009-01-28)
We present a self-stabilizing algorithm for routing messages between arbitrary pairs of nodes in a mobile ad hoc network. Our algorithm assumes the availability of a reliable GPS service, which supplies mobile nodes with ...
SoftCast: One Video to Serve All Wireless Receivers
(2009-02-07)
The main challenge in wireless video multicast is to scalably serve multiple receivers who have different channel characteristics. Current wireless transmission schemes, however, cannot support smooth degradation. Specifically, ...
Overcoming the Antennas-Per-Node Throughput Limit in MIMO LANs
(2009-02-18)
Today, the number of concurrent packets in a MIMO LAN is limited by the number of antennas on the AP. This paper shows how to overcome this limit. It presents a new design where multiple client-AP pairs can communicate ...
HAMPI: A Solver for String Constraints
(2009-02-04)
Many automatic testing, analysis, and verification techniques for programs can be effectively reduced to a constraint-generation phase followed by a constraint-solving phase. This separation of concerns often leads to more ...
The Art of the Propagator
(2009-01-26)
We develop a programming model built on the idea that the basic computational elements are autonomous machines interconnected by shared cells through which they communicate. Each machine continuously examines the cells it ...
