Mark S. Ackerman: Answer Garden: A Tool for Growing Organizational Memory

Answer Garden allows organizations to develop databases of commonly asked questions that grow "organically" as new questions arise and are answered. It is designed to help in situations (such as field service organizations and customer "hot lines") where there is a continuing stream of questions, many of which occur over and over, but some of which the organization has never seen before. The sy...

Combining Theories: The Ackerman and Guarded Fragments

Combination of decision procedures is at the heart of Satisfiability Modulo Theories (SMT) solvers. It provides ways to compose decision procedures for expressive languages which mix symbols from various decidable theories. Typical combinations include (linear) arithmetic, uninterpreted symbols, arrays operators, etc. In [7] we showed that any first-order theory from the Bernays-Schönfinkel-Ram...

Ackerman Steering Chassis with Independently Driven Back Wheels

When building the robot for outdoor competition the designer can choose from a variety of chassis. The differential drive and Ackerman steering drive are among the most popular. The paper describes our experiences with the custom built chassis that uses Ackerman steering principle together with independently driven back wheels. The chassis represent the base of Bender II mobile robot, used in R...

Lateral control strategy for autonomous steering of Ackerman-like vehicles

This paper presents the results of a lateral control strategy that has been applied to the problem of steering an autonomous vehicle using vision. The lateral control law has been designed for any kind of vehicle presenting the Ackerman kinematic model, accounting for the vehicle velocity as a crucial parameter for adapting the steering control response. This makes the control strategy suitable...
