Why
Due to the spread of communication robots, much attention has been paid to researches on human-robot interaction. To realize a society of human-robot coexistence, it is important for robots to recognize their working environment including human properly and to provide their services according to the situation.

How
We proposed a classification method of age groups (elderly and young people) based on the Support Vector Machine (SVM), which is a machine learning model, by using the movement data of people's legs obtained from a Laser Range Scanner (LRS) We constructed a predictor for the classification by using 25 samples.

Findings
We classified the elderly from the young with the accuracy of 80-90%. We also showed that the classification accuracy improved particularly by using acceleration and standard deviation as the feature values.
