Abstract:
Modeling and predicting human behavior is indispensable when
industrial robots interacting with human operators are to be
manipulated safely and efficiently. One challenge is that human
operators tend to follow different motion patterns, depending on their
intention and the structure of the environment. This precludes the use
of classical estimation techniques based on kinematic or dynamic
models, especially for the purpose of long-term prediction. In this
paper, we propose a method based on Hidden Markov Models
to predict the region of the workspace that is
possibly occupied by the human within a prediction horizon. In contrast to
predictions in the form of single points such as most likely human
positions as obtained from previous approaches,
the regions obtained here may serve as safety constraints
when the robot motion is planned or optimized. This way one arrives at
motion plans that are safe in the sense that plans avoid
collision with a probability not less than a
predefined threshold. The practicability of our method is demonstrated
by successfully and accurately predicting the motion of a human arm in
two scenarios involving multiple motion patterns.
