Work History
Senior Software Engineer
CSC Robotic Engineering Limited
07.2023 - Current
- Enhanced software functionality by identifying and resolving complex technical issues.
- Managed multiple robots simultaneously, while maintaining strict deadlines and high-quality standards.
- Coordinated deployments of new software, feature updates and fixes.
- Cooperating with the mechanical team to test and deploy a new process, and conduct optimization.
- On-site support for applying new functions, debugging, and solving problems.
- Using OpenCV to develop a marker recognition system to recognize markers with different shapes, colors, and sizes, and provide information about the markers, like score, center, angle, etc.
- Using a 3D camera and filtering the point cloud to calculate the normal vector of the drilling surface in order to align the end effector of the robot arm perpendicular to the surface. Sometimes, it may be combined with the IMU to align with the spirit level.
- Using PID control and force sensors to control the robot arm's moving speed during drilling in order to maintain the force level.
- Integrate the ROS MoveIt package to prevent arm collisions by using a 3D camera to recognize obstacles with point clouds and AI.
- Cooperating with the mechanical team to modify the tracked vehicle into an autonomous mobile robot with safety certification. Mainly in charge of safety control logic and circuits using Sick safety PLC with safety LiDAR and MOC module for monitoring the driving status of the vehicle in order to protect the laborers. Programming and setting up the motor drivers for the base controller and odometry. Integrated with LiDAR, IMU, and base controller to conduct SLAM and navigation.
- Documented software development methodologies in technical manuals to be used by IT personnel in future projects.
- Integrating the drilling process and an autonomous tracked vehicle using a BIM diagram as the map to conduct a fully automated drilling robot.
