Course Search, Navigate, and Actuate

"Zoeken, Sturen en Bewegen"

This is the information of year 2017.

The previous years Arnoud Visser was also responsible for this course, the 2015 and 2016 are still available. In 2013 and 2014 the course was coordinated by Toto van Inge. His site could be found here.
The experiments of the last weeks are listed on a separate page.

Description

The official description of course baiZSB6 can be found (in Dutch) here. The organization of the course can be found in the Studiewijzer. Also a Blackboard portal to this information is available. Blackboard is mainly used for email and grading.

Contents

• Search Algorithms
  Game playing is an example of type of problems that can easily decomposed in subproblems. For interesting games, like chess, the tree of subproblems grows to fast to be searched exhaustively, so other approaches are necessary. To solve the game we have to find a solution tree regardless of the opponent's replies.
  • MiniMax principle
  • alpha-beta algorithm
  • increasing the effectiveness with advice rules

• Trajectory planning
  If you have setpoints, how to make it into a controllable path.

• Rigid body motion
  • physical rigid bodies as idealization
  • physical space as vector space
  • representing motions using linear algebra (coordinate-free)
  • isometries
  • proof of decomposition theorem: rigid body motion = rotation followed by translation
  • coordinates: vector spaces in the computer
  • rotation matrices: how to design them
  • reference angles: Euler angles
  • homogeneous coordinates

• Kinematics of linked mechanisms
  • Denavit-Hartenberg notation
  • Forward kinematics
  • Inverse kinematics (briefly)
  • Redundancy and degeneracy (briefly)
  • Differential kinematics

Week 26

It is not the result that counts, but your summery of your survey. Document your progress, experiments and decisions in a LabBook.

With a working system, and the acquired knowledge, you can explore new possibilities.

Here are the surveys of the previous years:

• the surveys of the 2015 students, see Experiment2015
• the surveys of the 2014 students, see Experiment2014
• the surveys of the 2013 students, see Experiment2013
• the surveys of the 2012 students, see Experiment2012
• the surveys of the 2011 students, see Experiment2011
• the surveys of the 2010 students, see Experiment2010
• the surveys of the 2009 students, see Experiment2009
• the surveys of the 2008 students, see Experiment2008
• the surveys of the 2007 students, see Experiment2007
• the surveys of the 2006 students, see Experiment2006
• the surveys of the 2005 students, see Experiment2005
• the surveys of the 2004 students, see Experiment2004

• Path-planning for a Hemisson-robot
• Maze navigation with a Pepper-robot
• Looking to a talking person with a Nao-robot.
• Extend the checkmate problem to more complex situations
• Refine the visualisation of the Virtual robot.
• Creating a gamepad interface for a virtual Aibo (Visual Basic)
• WiiBot RTX UMI
• Solve chess endgame with Monte Carlo tree search (MCTS)
• Hacking the Neato XV-11
• Programming the Concept Wheels of Ramon Lull.

You will be evaluated on your LabBook at the end of the week.

Evaluation

In 2017 the course was overall evaluated by the participants with a 7.4:
.

Literature

For the implementation in prolog we will look at chapter 24 of Prolog Programming for Artificial Intelligence by Ivan Bratko. The companion website of the 4th edition is not yet available, the companion website of the 3th edition contains several student resources.
This book was explored until chapter 13 in the previous course Logic Programming and Search Techniques.

Further we use the syllabus 'An Introduction to Robotics' by Leo Dorst, which is available for download at the Blackboard site.

Inheritance

In the old days, when Bachelors were not schooled at Dutch Universities, a different course was given with another focus. Still, much can be learned from the course 'Robotica'.
