DAEMON
THE GUIDING SPIRIT
Training manipulation policies requires thousands of trajectories. DAEMON sidesteps this — overlay visual trace prompts on observation frames, and the robot learns from the hint. Draw the path, the robot follows. Proprioception traces are instant, calibration-perfect, and commercially licensed.

VLA MODELS NEED ACTION GUIDANCE AT SCALE
Training manipulation policies requires thousands of robot trajectories. Current VLA models improve with scale but falter on novel tasks. They need action guidance — a way to hint at the solution without dense trajectory labels. You can't annotate trajectories at scale.
Humans solve this instantly: show the arm where to go. But how do you encode "trajectory" into an image-based policy? You need a visual prompt — draw on the observation frame where the gripper should move, and the policy learns from that hint. No one had productized this until TraceVLA.
WHAT DAEMON DELIVERS
DAEMON augments Vision Language Action models with visual trace prompting. It overlays robot end-effector trajectories as drawn paths onto observation frames, conditioning policy inference on visual guidance.
CAPABILITIES
- Two trace generators: Proprioception (commercial-safe, MIT) and CoTracker (research-only, CC-BY-NC)
- Proprioception path: forward kinematics → 2D projection → draw on frame (zero latency)
- OpenVLA-7B policy inference with finetuning on custom datasets
- Multi-device: MLX (Apple M1–M5), CUDA (RTX 4090, A100), CPU fallback
- Real-time policy prediction: 20-100 inferences/sec on GPU, ~30+ on M5
- LiDAR simulator (Gazebo Harmonic) + SimplerEnv benchmark integration
WHY THIS IS HARD
Visual trace prompting is a new paradigm. It requires solving:
- 01Trace generation: real-time proprioceptive forward kinematics (calibration-critical) or optical flow tracking
- 02Policy runtime: OpenVLA inference on multiple devices — MLX bootstrap, CUDA Torch, CPU fallback
- 03Finetuning: dataset preprocessing, distributed training on 1-8 GPUs, custom normalization per domain
- 04Licensing discipline: CoTracker is CC-BY-NC (research-only); proprioception must be used for commercial
- 05Evaluation: SimplerEnv benchmark requires Gazebo simulation and complex task definitions
DAEMON handles all of this. Proprioception traces are instant, provably correct, and MIT-licensed. CoTracker is available for research but disabled in production.
