Robot Perception Skill
When to Use This Skill
- Setting up and configuring camera, LiDAR, or depth sensors
- Building RGB, depth, or point cloud processing pipelines
- Calibrating cameras (intrinsic, extrinsic, hand-eye)
- Implementing object detection, segmentation, or tracking for robots
- Fusing data from multiple sensor modalities
- Streaming sensor data with proper threading and buffering
- Synchronizing multi-sensor rigs
- Deploying perception models on robot hardware (GPU, edge)
- Debugging perception failures (latency, dropped frames, misalignment)
