Milrem Robotics is behind some impressive robotic ground and combat vehicles. Their THeMIS Observe is also worth a look. It is an autonomous Intelligence, Surveillance and Reconnaissance (ISR) unmanned ground system with follow-me and waypoint navigation with obstacle detection and avoidance.
The THeMIS Observe uses a Z:Sparrowhawk camera from HENSOLDT, Squire radar by Thales, Metravib Defence Pearl acoustic shot detection and the ROSY (Rapid Obscuring System) by Rheinmetall. It can be equipped with a light remote weapon station. You can find out more about it here.
