Press release of University of Bonn: Roboter überzeugt beim DLR SpaceBot Camp


Our team NimbRo Explorer solved through the mobile manipulation robot Momaro all tasks at the DLR SpaceBot Camp: taking a soil sample, finding and grasping two objects, transporting them to a basis object, assembly (placing the soil sample at a scale and inserting a battery pack) and operating a switch.

Our team NimbRo Explorer participates with the mobile manipulation robot Momaro at the DLR SpaceBot Camp 2015 in Hürth.Ten teams from leading German robotics labs will demonstrate semi-autonomous mobile manipulation in a moon-like environment. Based on a coarse map, the robot must explore the arena, find two objects, take a soil sample, transport the objects to a base and assemble them there. Communication to the operator crew is possible only sometimes and has 4 seconds latency.

Our team NimbRo Explorer qualified as first of the ten qualification event participants for the DLR SpaceBot Cup. Through the mobile manipulation robot Momaro, our operators solved all three qualification tasks in the first attempt. The DLR SpaceBot Cup qualification event took place in Bonn.

Representatives of DLR and the network provider visited our lab. The DLR communication network was tested sucessfully. The Momaro robot was demonstrated.


Our new mobile manipulation robot Momaro was tested at the DARPA Robotics Challenge in Pomona, CA. Our team NimbRo Rescue was ranked as the best European team, comming in 4th in the overall ranking. Though the Momaro robot, the operators solved seven of the eight possible tasks in only 34 minutes: driving a car, climbing out of the car, opening a door, turning a valve, cutting a hole in a wall, traversing debris, and a surprise task, which was operating an electrical switch. More information.

Our Team NimbRo Explorer is supported by the German Aerospace Center to participate at the DLR SpaceBot Cup 2015.

DLR SpaceBot Cup 2015

Tasks in this challenge are semi-autononomous mobile manipulation in rough terrain. The Kickoff meeting took place in Bonn.

In the afternoon, all teams had the opportunity to simultanously operate their robots in the arena. Our Explorer robot demonstrated autonomous grasping and storage of the battery pack and autonomous removal of the battery pack from its holder. It also removed the cup from the holder and placed it on the scale. The jury decided to award no trophies to any of the teams. No competition scores have been communicated to the teams so far.

Our Explorer robot had its run in the unknown arena today. It created a 3D map of the terrain and navigated to one of the objects that where placed in the arena. It grasped this water-filled cup autonomously and placed it in the holding mechanism without spilling any water. After the official run ended, the robot navitated to the other side of the arena and climbed a hill.

We tested in a small area outside the arena. We also tested the ground station and the network provided by DLR.
