Research agenda

A long-term research program for robot runtime, diagnosis, and reliability.

How can robot missions be recorded, failures replayed, diagnoses linked to evidence, and engineering improvements verified?

Robot Runtime Observability

How can a robot run retain its state, versions, environment, and task context?

Connect topics, TF, logs, parameters, maps, and task events into run records that can be queried and compared.

Failure Replay & Diagnosis

How can fragmented data reconstruct a failure timeline without losing the original evidence?

Study reproducible and explainable incident review through Episodes, Incidents, and Evidence.

Navigation Reliability

How do TF, odometry, localization, planning, and control combine to produce navigation failures?

Build a body of SLAM, Nav2, and sensor-chain failure cases around ROS 2 differential-drive robots.

Research method

Research must return to verifiable engineering results.

Reproducible systems

Begin with simulation and progressively introduce recorded runs.

Complete run evidence

Preserve rosbag2, logs, parameters, maps, and software versions.

Episode reconstruction

Rebuild a mission timeline and its operating context.

Diagnosis and improvement

Trace conclusions to evidence and validate fixes through repeated experiments.

Research object

Study one mobile-robot loop deeply.

The current scope is a ROS 2 differential-drive robot across sensors, TF, odometry, SLAM, localization, planning, and control. A focused boundary enables comparable data and failure cases.
