Everything You Need as a Robotics Engineer: A Look Inside Our High-Tech Office
A behind-the-scenes look inside Mujin's 14,500 m² Tatsumi Robot Center: 60+ real industrial robots, large-scale physics simulation clusters, multi-maker integration, and the engineering culture empowering robotics developers.
Do you have an unyielding passion for robotics, mechanical systems, and cutting-edge software? Do you find joy in solving complex physical problems and deploying real robots to perform tasks previously deemed impossible?
If so, industrial robotics offers one of the most intellectually rewarding fields in modern engineering. At Mujin, we empower engineers to harness their creativity, bridge the gap between academic theory and physical reality, and build production-grade autonomous systems.

The Hardware Playground: 60+ Robots Under One Roof
Precision in industrial robotics is governed by the laws of physics. As an arm’s reach and payload increase, structural deflection, joint compliance, and inertia amplify millimeter deviations into critical positioning errors. Solving these challenges requires testing on real physical hardware.
From our humble beginnings in a 41 m² garage in Koishikawa, Mujin’s Tokyo headquarters has grown into the 14,500 m² Tatsumi Robot Center—one of the largest private robotics facilities in Asia.
Heavy-duty industrial manipulators capable of handling payloads up to 190 kg
Full-scale testbeds integrating mobile AGVs, roller conveyors, and pallet racks
- Diverse Robot Fleet: Over 60+ distinct robot models are actively operational across our engineering and testing bays. Because MujinController is hardware-agnostic, our floors feature arms from FANUC, Yaskawa, Kawasaki, Mitsubishi Electric, KUKA, and ABB.
- Massive Heavyweight Payloads: We deploy heavy industrial arms handling up to 190 kg, equipped with custom-engineered end-effectors and suction frames that alone can weigh over 70 kg.
- Integrated Warehouse Ecosystems: Beyond robot arms, the center features high-speed pallet conveyors, autonomous mobile robots (AGVs/AMRs), safety interlocks, and sensor rigs mimicking client distribution hubs.

Software & Digital Twins: Simulating the Physical World
While the mechanical hardware provides raw power, the software determines whether the system succeeds in unstructured environments.
Our flagship platform, MujinController, is powered by MujinMI (Machine Intelligence), coordinating up to ten degrees of freedom with analytical inverse kinematics and real-time collision checking.
Software engineering at Mujin: seamlessly combining high-performance C++, Python, and digital-twin simulation clusters
Large-Scale Simulation Clusters
Testing every corner case on physical hardware would be impractically slow and risk collisions. We maintain high-density compute clusters that run thousands of automated physics simulations nightly—modeling motor temperatures, friction, and joint limits.
Modern Engineering Toolchain
Our core codebase utilizes C++ for hard real-time execution, Python for data manipulation and tooling, with Go and C# across distributed services and cloud telemetry.
Empowering Engineers: Our Culture & Community
Solving open problems in robotics is notoriously difficult because real-world physics doesn’t offer trivial closed-form answers. Real-time path planning in high-dimensional configuration spaces requires balancing trajectory smoothness, cycle time, and obstacle clearances within fractions of a second.
Fast-Track Growth
Career progression is driven by capability and passion, not tenure. Several team leads joined Mujin as university interns and rose to leadership roles within five years.
Flat, Direct Communication
Our open office layout eliminates corporate bureaucracy. Developers can walk directly to the CEO, CTO, or head of hardware to discuss ideas or resolve blockers.
Production-Grade Impact
The algorithms you write and debug today don’t stay in academic papers—they run 24/7 in state-of-the-art warehouses across Japan, the US, and Europe.
