What is DataSnack?
DataSnack introduces Crumb, the black box for robots — an independent, tamper-proof event recorder designed for deployment on autonomous systems. Crumb continuously records sensor data from LiDAR, depth cameras, IMUs, and mesh networks, cryptographically sealing each data stream to ensure integrity and non-repudiation. This hardware module operates autonomously, requiring no external power or network connectivity, making it ideal for post-incident analysis, regulatory compliance, and debugging in robotics applications.
Key features include cryptographic sealing of all recorded data, ensuring that logs cannot be altered or deleted without detection. Crumb supports multiple sensor inputs simultaneously, capturing high-frequency data from LiDAR point clouds, depth maps, inertial measurements, and mesh communication packets. The device is built for harsh environments, with a ruggedized enclosure that withstands shock, vibration, and temperature extremes. It offers plug-and-play integration via standard interfaces (USB, Ethernet, CAN bus) and can be configured to trigger recording based on events or continuously loop over a fixed storage capacity.
Benefits for robotics teams include enhanced safety and accountability, as Crumb provides an immutable record of robot actions and environmental conditions. This is critical for autonomous vehicles, drones, industrial robots, and service robots operating in public or sensitive areas. Use cases include accident investigation, where Crumb's sealed logs serve as legal evidence; performance optimization, by replaying sensor data to identify software bugs; and compliance with emerging regulations requiring black boxes for autonomous machines.
Technical details: Crumb uses AES-256 encryption for data at rest and SHA-256 hashing for integrity verification. Storage capacity ranges from 128GB to 1TB, supporting weeks of continuous recording depending on sensor data rates. Power consumption is under 5W, allowing battery-backed operation for up to 24 hours. The device measures 100x70x30mm and weighs 200g, fitting easily into most robot chassis. DataSnack provides SDKs for Python, C++, and ROS to integrate Crumb into existing robotic stacks, with APIs for retrieving sealed logs and verifying signatures.
In summary, Crumb by DataSnack is the essential black box for any robot, offering tamper-proof recording, broad sensor support, and robust construction for mission-critical applications.
