Data Collection Throughput

Real-world benchmarks from SVRC data collection sessions using the DK1.

~15 Demos / Hour

Pick-and-place tasks (grab object, move to bin). Each demo takes ~2 minutes including reset. An experienced operator collects 15-20 demonstrations per hour.

~8 Demos / Hour

Multi-step manipulation (open drawer, pick object, close drawer). Longer episodes (~4 min each) with more complex reset procedures.

~50 GB / Day

At 30 Hz with 3 cameras (640x480 JPEG), a full day of collection produces ~50 GB of JSONL + image data. The SVRC platform auto-compresses and indexes.
