Four legs.
Every one a track.
We are building a modular rescue robot: four tracked legs, a robotic arm on top, and tools that come off with a handful of screws. First stop is the RoboCup Rescue world championship in Germany.
Swap the parts, keep the robot
One base that changes with the job. The chassis, the arm and the tool on the arm are separate modules, so a broken part or a new task means a swap, not a new robot.
Tracked legs, or real legs
The all-terrain version stands on four tracked legs that tilt to climb steps, stairs and rubble. The same body is meant to take a walking leg set later.
Off with ten screws
The arm sits on a standard mount. Undo about ten screws and a different arm goes on, from a simple manipulator to a heavier one.
A tool for each task
Gripper, a human-like hand, a camera head, a water nozzle. The end of the arm is a quick-change point of its own.
Sized by the competition rulebook
RoboCup Rescue sets hard limits and real tasks. Version 1 is designed around them, then grows into the work the robot is really for.
| Mass | Under 40 kgLeague limit is 80 kg |
|---|---|
| Legs | 4 tracked flippersClimb 20 cm steps and stair risers |
| Arm reach | Tasks on rails 60 cm above the floor |
| Gripper | Opens to 10 cm, lifts 5 kg objects |
| Autonomy | Runs on boardMapping and detection keep working if the radio drops |
| Safety | E-stop, carry handles |
Targets, not measurements. The robot is in design.
The test course for first responders
The league builds standard disaster terrain and scores how reliably a robot crosses it and works in it. The operator sits away from the arena and sees only what the robot sends back.
Climb up, cross, climb down.
Slopes that tilt the robot sideways.
Uneven blocks that trap tracks.
Trip obstacles at an angle.
Shifting terrain with buried frames.
Stairs with rubble, up or down.
Push or pull, lever handle, weighted closer.
Map it live, find the targets.
Terrain as set in the 2026 rules. The 2027 rules come out in spring.
Autonomy is worth fifteen times more on the same lane. That is why we design for on-board autonomy from day one, not as an add-on.

One platform, three jobs
Rescue is the hardest test. What passes it carries over to two more lines of work, developed at the same time.
Where people shouldn't go first
Collapsed and damaged buildings, stairs, rubble. Drive in, map, find, report back.
Robots on the building site
Swap the rescue tools for building tools and use the same tracked base to help build and refurbish houses.
Plants that look after themselves
Stacked hydroponic growing, watered automatically. The robot moves along the stacks, plants and harvests.
Skills for our robots, and for everyone else's
A robot is only as useful as what it knows how to do. Alongside the hardware we are building a platform of skills: ready behaviours you load onto a robot, from picking and placing to inspection routines.
It starts with skills for our own modular robot and opens up to other platforms, including humanoids.
We are looking for builders
The team starts small and grows with the robot. Former members of SERS, the RoboCupJunior team that won the SuperTeam challenge at RoboCup 2026 in Korea, are helping out. We need students who want to build.
Mechanical design and fabrication
CAD, tracks, flipper legs, the arm mount. Turning drawings into parts that survive a stair climb.
Electronics and power
Motor drivers, batteries, wiring, the e-stop chain.
Autonomy and perception
Mapping, navigation, detection, running on the robot itself.
Operations and partners
Testing, operating the robot at competition, sponsors and media.
- Compete at the RoboCup world championship.
- Work on real hardware, from the first drawing to the competition floor.
- Your name on the team description paper.
Write a few lines about what you study and what you would like to build.
Help a student-built rescue robot get to Nürnberg
We are looking for sponsors and partners. Support can be money, parts or time.
- Motors, drives, batteries and sensors for the robot.
- Machining, laser cutting and 3D printing.
- A space to build and test a practice course.
- Travel for the team to the world championship.
