Jan 1, 2026Month: 2026-01 | Repository: ROAR-QUTRC/perseus-v2 Key deliverables: - CUDA Demo Suite for Jetson: Runtime and Performance Enhancements. Consolidated CUDA demo tooling with improved Jetson runtime compatibility. Enhanced nixcuda wrapper to include Jetson library paths, added a real-time CPU vs CUDA performance demo with matrix multiplication and Mandelbrot variants, and improved cuda-demo.sh reliability through better escaping, cleanup, and argument handling. - Build Cache Optimization for Perseus-v2: Introduced a dedicated Cachix cache to accelerate builds by leveraging multiple cache sources. Major bugs fixed: - Jetson CUDA library path handling: Fixed by adding /usr/lib/aarch64-linux-gnu/tegra and /usr/local/cuda/lib64 to nixcuda wrapper to ensure CUDA programs locate drivers at runtime. - Script robustness: Resolved shellcheck warnings, improved trap cleanup, and updated references to pass arguments directly in cuda-demo.sh. Overall impact and accomplishments: - Achieved faster, more reliable embedded CUDA validation workflows on Jetson, enabling faster iteration of AI demos and performance comparisons. - Reduced build times and CI latency for Perseus-v2 by leveraging Cachix caches, improving developer throughput. Technologies/skills demonstrated: - CUDA GPU programming and performance benchmarking, Jetson/Linux path management, advanced bash scripting and shell scripting best practices, and build caching with Cachix/Nix.

Dec 1, 2025December 2025 monthly summary for ROAR-QUTRC/perseus-v2 focusing on Teleoperation Diagnostics and motion control improvements. Delivered a curses-based Teleoperation Diagnostics TUI as a new ROS2 package with a fallback text mode, enabling robust debugging and operator visibility in both interactive and headless environments. Implemented runtime discovery of twist_mux priorities and generic controller configurations, plus axis scaling corrections aligned to ROS conventions. Refined wheel dynamics and URDF in simulation, and adjusted Xbox controller configuration to improve realism and operator usability. Reduced external dependencies by replacing rich with curses, and added resilient defaults and headless support. The work enhances observability, reduces setup friction, and accelerates safe teleoperation and testing in simulated & real-world scenarios.
