start of the project: October 2004

In February 2005 the Interim Thesis has been appeared and a presentation has been given.

The Master project has been finished in August 2005 ( Masters Thesis). For working address etc. we refer to our alumnipage.

Summary of the master project:
Frog Navigation Systems BV, located in Utrecht, The Netherlands, produces guided vehicles, together with a control computer and a supervisory system. Much software has been developed, which is currently enhanced and renewed. One of the latest developments is the inclusion of NURBS to define the route.

A tool has been developed to draw the routes, which are used to guide the vehicle. The tool is used in practice, however a number of topics remain to be investigated in order to make the tool more versatile. Below some of these topics are given:

  1. NURBS curve synthesis using a model for the vehicle.
  2. Determine the critical section in a layout.
  3. Synthetise NURBS routes with constraints on the available space.
  4. Hull curve detection by guiding a vehicle with two control points over a NURBS curve.
  5. Approximate a NURBS route over a serie of points.
  6. Reparameterise a NURBS curve to the length of the curve.
  7. Define the position and the orientation of a vehicle using higher dimensional NURBS.
  8. Add new routines to the NURBS library in C++.
