Robotics is a very interdisciplinary area in theoretical research and
development and in engineering and industrial applications.
This session of ACA concentrates on the aspects of
symbolic computation (SC) and computer algebra (CA) deployment in robotics.
Natural applications are symbolic modeling of robot arms
(kinematic chains) and their computational treatment by methods of CA.
Typical problems amenable to such CA approaches are (inverse)
kinematics problems and detection of singularities in robot arm
movements (and also singular configurations in so-called
parallel manipulators). Other challenging problem fields are
(among others) dynamics, path tracking, obstacle avoidance,
finding collision free paths. We further mention the very complex
problem area of cooperating and communicating robots and production cells.
(The above list is far from being exhaustive).
CA applications to modeling kinematic chains lead to hard performance
problems when the degree of freedom of a robot arm increases.
Hybrid approaches mixing SC with numerical methods seem to be promising.
