Building a physical API
A developer built a Rust-based system that converts raw CAN bus traffic from a robot into structured telemetry via a physical API, enabling real-time monitoring and control.
- A Rust daemon named Sentinel converts raw CAN bus traffic from a robot into structured telemetry data.
- The system uses a time-series database to store telemetry and Grafana for real-time dashboards and alerts.
- A live 3D model of the robot arm mirrors its physical state, enabling intuitive control and monitoring.
- This approach bridges industrial robotics hardware with modern software practices for better observability.
A developer documented their process of creating a physical API for a robot by leveraging a Rust daemon named Sentinel. This daemon listens to the robot's CAN bus traffic, transforming it into structured telemetry data. The system integrates a time-series database to store this data, Grafana for real-time dashboards and alerts, and a control plane featuring a live 3D model of the robot arm that mirrors its physical counterpart in real time.
The approach highlights a novel way to bridge low-level robotics hardware with high-level software interfaces, enabling developers to monitor, analyze, and control robotic systems more effectively. By abstracting CAN bus data into a standardized API, the project demonstrates how traditional industrial robotics can adopt modern software practices for better observability and automation.
