The project utilizes UR5e from Universal Robots for automated screw driving.

The novelty of this system lies in the integration of a depth camera mounted on the end effector, enabling the robot to adapt to different screw-hole locations without manual tuning.

  

We won the 2024 UNSW MTRN4231 Course Competition

SIEMENS Process Simulate Plugins

Project Duration: 8 weeks

Language used: C#

Background: Process Simulate from SIEMENS is a software used by simulation engineers at FFT Shanghai to improve, verify and validate the correctness and plausibility of the welding production system design.

What does the plugin do: To improve efficiency by reduce repetitive work, I was assigned to design a plugin that generates a table showcasing the joint angles of the robot at each via-point. The plugin also highlights the via-points that are near joint limit or potential singularities.

Impact & Result:

• The plugin passed the internal screening and entered Alpha testing phase by the time I completed the internship.
• The plugins were described by the simulation team lead as “handy tools that will be used every day and save more than 3 hours on each project”.
