The Asguard v4 is a leg-wheel hybrid which can be used in difficult outdoor environments. The system was designed on the basis of the predecessors in the Asguard series. The main improvement of the v4 system is in the modularity of the subsystems. Like the v3 version, Asguard v4 has a powerful on-board PC, which can be used to process the sensor data from the Laser-Range-Finder, the Cameras and IMU so that the system can operate in unknown terrain. Asguard does not rely on an external power supply, but can operate for multiple hours with its on-board batteries. The system can be tele-operated via videolink, but also has the ability to autonomously perform waypoint navigation with local obstacle avoidance. The powerful motors allow the system to carry payloads of multiple kg in mass.
