Robo-roach for studying thought process

Researchers have developed
'Roach-bots' because they want to get inside the mind of this lowly insect pest
to help invent new ways to control them.

The Roach-bots were able to
guide cockroach swarms when they rushed to find a shelter. More fascinatingly,
the 'bots coaxed the whole group to behave in unusual ways, so they will provide
a tool for scientists to investigate the thought processes of this pest.

Seems like another plaything for scientists.

For the life of me, I cannot understand why you want to study the thought process of a cockroach.
