Cerulion is middleware for robots - it abstracts away the process of interfacing with the motors and sensors. Visualization, data logging, and control can be easily achieved in a no-code GUI.

### Open source operating system for robots

Cerulion is an open source operating system for robots built by 2 MIT robotics PhDs. Companies like Amazon Robotics and Boston Dynamics AI Institute are using us to develop faster and ship more reliable robots than with ROS. With up to 1000x improvements in communications performance over state of the art, Cerulion is enabling the next generation of embodied AI.

### Active Founders

### Lakshay Sharma, Founder/CEO

Lakshay is the cofounder/CEO of robotics middleware startup Cerulion. Prior to this, he studied computer engineering, astrophysics and robotics at the University of Pennsylvania, and researched robot motion planners at MIT.



### Se Hwan Jeon, Founder

I'm the cofounder of Cerulion along with Lakshay Sharma. Cerulion is a software interface and abstraction layer to make controlling, debugging, and visualizing commercial robots accessible to everyone. Prior to YC, I studied mechanical engineering at the University of Notre Dame and MIT, specializing in robotics, optimal control, and reinforcement learning for legged platforms.



### Company Launches

[### Cerulion 🤖 Fast, reliable, cross-platform robot middleware](

Robots are expensive and hard to develop/debug. [Cerulion]( solves the robot tooling problem to cut down development times by up to 10x.

The Problem
-----------

The incredibly high capital costs required for robotics, combined with the inherently non-deterministic nature of embodied intelligence, result in an unpredictable system where even attempts, let alone failures, are cost-prohibitive.

**Robots are expensive and hard.**

And yet, despite time on hardware being such a precious resource, roboticists today are absolutely wasting 90% of it fighting against unoptimized tooling. Some common complaints are:

*   Needlessly complex to install, maintain, and document
*   Incredibly steep learning curve for non-transferable skills
*   Poor observability into a robot's belief
*   Artificial non-determinism induced by slow or unreliable message-passing
*   Unreliable network protocols and IPCs
*   System breakdown due to poor inter-robot communication
*   Unreliable logging and cumbersome/nondeterministic log replay
*   Wasting precious field time parsing 1000s of lines of runtime errors whooshing past the screen

And the list goes on and on.

**Robot tooling today is broken. Unacceptably so.**

Our Solution: Performance never looked this good!
-------------------------------------------------



*   **Packaged as an app, rather than a CLI tool:** Instead of shipping as a bunch of CLI tools to be installed, patched, and reinstalled, Cerulion is an app you can download on Windows, Mac, or Linux. It will smartly detect and handle any dependencies as needed.
*   **Intuitive, cross-platform visualizer:** The sleek, easy-to-use GUI is the main way of communicating with your robot in the field, which means you can run it with minimal resources on your favorite long-lasting laptop with any OS, instead of **_that_** RGB laptop with a gaming GPU running Linux.
*   **Minimal boilerplate and setup:** The way you program robots in Cerulion is designed to get out of your way, so you can focus on the planner and perception algorithms instead of worrying about the inter-process comms, IP addresses, or network routes.
*   **Fast and reliable communication:** We leverage cutting-edge Rust-based networking and IPC stacks like [Zenoh]( and [IceOryx2]( along with tried and tested C++ alternatives like [LCM]( and [IceOryx]( By ensuring communications don't fail silently and messages are delivered when expected, Cerulion eliminates nasty surprises in safety-critical scenarios.
