Marcus Lim
Systems Engineering Project
What:
To design an arena that strategically hinders competitors robots while ensuring our AgileX Limo robot can navigate through obstacles set with similar intensity.
How:
- Applying systems approach to ensure seamless integration between mechanical design, electronics and robotic software (ROS)
- Introducing obstacles that challenges the limits of the robot's LIDAR sensors
- Implementing confusing electronics that could potentially delay our opponents
- Optimizing obstacle inflation radius in sensors to ensure the robot is able to identify obstacles while still pass through tight gaps
Key Takeaways:
- Gained an understanding of designing and integrating a system
- Synthesizing, analyzing and selecting the best alternative
- Project management and team collaboration across disciplines
- Proficient understanding in using LiDAR sensors and depth cameras to ideate obstacles and develop efficient navigation strategies
