  This paper presents a very compact 16-node cluster that is the core of a
future robot for collecting and storing massive amounts of sensor data for
research on Simultaneous Localization and Mapping (SLAM). To the best of our
knowledge, this is the first time that such a cluster is used in robotics. We
first present the requirements and different options for computing of such a
robot and then show the hardware and software of our solution in detail. The
cluster consists of 16 nodes of AMD Ryzen 7 5700U CPUs with a total of 128
cores. As a system that is to be used on a Clearpath Husky robot, it is very
small in size, can be operated from battery power and has all required power
and networking components integrated. Stress tests on the completed cluster
show that it performs well.
