PROFILE
Callum
Callum Wong contributed to thedropbears/pyreefscape by developing and refining autonomous robotics features focused on algae collection and control systems. Over four months, he implemented multi-leg path planning, trajectory generation, and state machine-based climber controls using Python and embedded systems techniques. His work included integrating 3D modeling and animation for simulation, improving teleoperation safety, and enhancing test-mode workflows. By refactoring core components and simplifying measurement and depositor logic, Callum reduced operational risk and technical debt. These changes resulted in more reliable autonomous navigation, safer live operation, and faster validation cycles, demonstrating a strong grasp of robotics software engineering and system design.

Jun 1, 2025June 2025: Delivered two high-impact features for thedropbears/pyreefscape, strengthening control flow, improving user interaction, and reducing technical debt. Climber readiness gating moved into the climber state machine with direct A-button retraction, boosting reliability and usability. Coral Depositor component removed from autonomous base and robot control, simplifying the codebase and reducing runtime risk. Tests updated to reflect state-machine changes, improving coverage and clarity. Result: more reliable missions, faster iteration, and easier maintenance.

Feb 1, 2025February 2025 (thedropbears/pyreefscape) focused on boosting algae shooting reliability, multi-leg path planning, and testing capabilities. Key deliverables include algae pose variable management with defined intake, branch, and shoot pose vars, plus alignment of shoot pose to the centre using translation waypoints. Completed multi-leg path generation for left, centre, and right legs, including a CentreAuto refactor and trajectory updates. Regenerated Alliance Start/StartToBranch paths to align with updated trajectories. Addressed path integrity and safety issues: removed a duplicate waypoint in AlgaeCDToShoot, ensured zero chassis velocity before algae shooting, and eliminated retreating paths to fix routing issues. System updates replaced the placer with a depositor and updated the injector; test-mode UI buttons and tuck controls were added to improve testing. Overall impact includes reduced operational risk, more reliable autonomous path planning, and faster validation cycles, enabling safer, repeatable deployments.
