Additional Information
- Budget
- Over $1000
- Challenges Faced
- Main challenges:
- fitting mounting geometry with 0.5 mm precision and 3D printing the parts
- setting up live streaming and fine-tuning its parameters
- immature open-source software components
- video stream stabilization
- making all components work together reliably
- having to learn many things from scratch in order to hide the complexity behind simple configuration forms
- the “drunk car” effect caused by latency above 50 ms
What needs improvement:
- replacing direct joystick-to-servo coefficient streaming with course control based on a gyroscope and IMU
- obstacle avoidance and lane keeping
- moving away from direct control toward task-based control
