Scientists at Birmingham University are testing their latest project by putting an autonomous robot in a working office environment to do a real job.
Bob, a robotic security guard, is patrolling the Tewkesbury office of security company G4S.
He scans rooms, looking for differences from previous scans and reporting any anomalies.
