Generating flexible collision-free reaching move-
ments is a standard task for autonomous articulated robots that
is critical especially when such systems interact with humans in
a service robotics setting. Current solutions are still challenging
to put into practice. Here we generalize an approach
first
used to plan end-effector movement that is based on attractor
dynamical systems. We show, how different contributions to
the motion planning dynamics can be formulated in constraint-
specific reference frames and then transformed into the frame
of the joint velocity vector. We implement this system on an
8 DoF redundant manipulator and show its feasibility in a
simulation. A systematic experiment with randomly generated
obstacle scenes characterizes the performance of the system.
Especially challenging confi
gurations of obstacles are discussed
to illustrate how the method solves these cases
This paper deals with the question how to integrate smart devices in Java appli-
cations. It will outline how different smart devices can be used to enrich learning
environments, we will point to some of the problems one has to face while dealing
with smart devices, a differentiation of smart devices will be done and we will give an
overview about existing Java Virtual Machines available for different smart devices.
Furthermore we will tackle the question of the communication between different smart
devices and also between different kinds of smart devices. An outlook to the future
work will also be given at the end of this work
