The workbenchSeven builds

Software, machine learning, and the things with wires coming out of them.

Open the garage

Mar 2026 to present, robotics and edge AI

Iron Bark, autonomous VLA robot dog

A multithreaded perception pipeline combining YOLOv11 object detection, multi-shot ArcFace biometric enrollment, and a vision-language model across a distributed Pi 5 and GPU compute architecture.

  • Eliminated VLM hallucinations with YOLO-grounded prompting: real-time detection counts get injected into the VLM context.
  • Swapped LLaVA-7B for Moondream and cut latency 4.7x.
  • Behavior state machine, IDLE to FOLLOW to SEARCH to EXPLORE, with hysteresis-based transitions over a dual-camera edge system on ZeroMQ.

Jul 2025 to present, generative models

Rembeetle

A real-time multimodal inference pipeline with sub-second latency, orchestrating Whisper ASR, GPT-4o, TTS, and Silero VAD for bidirectional voice AI in asynchronous Python.

  • Retrieval-augmented generation with Google OAuth (ES256/JWKS), asyncpg Postgres with per-user data isolation, and pgvector cosine similarity over 1536-dim embeddings.
  • Agentic pipeline on the Model Context Protocol with streaming JSON parsing, so tools are discovered and called at runtime.

Sep 2025 to Nov 2025, computer vision

Voice-controlled robotic arm

A 4-DOF autonomous robotic arm driven by a custom-trained YOLOv11 model, executing spoken commands through computer vision.

  • Deterministic control state machine with 7-point linear interpolation mapping camera depth to servo angles at 0.5-degree actuation accuracy.
  • Vision at 8 FPS on a host PC, coordinates streamed over low-latency UDP to a Raspberry Pi embedded controller.

Oct 2024, AI and hardware

The Carbeetle Project

Vehicle classification with automated garage access. A YOLOv11 model on a Raspberry Pi watches a live camera feed, recognizes the family E46, and fires a relay to open the garage door on sight.

Thermal performance predictor

Time-sequential neural networks (LSTM, GRU, RNN, RBF-RNN) standing in for slow thermal energy storage simulations. Research is ongoing. Discharge patterns are still to be trained.

Sep 2024, AI in education

Automated Python quiz generator

GPT writes programming quiz questions for UC Irvine's intro course, a synthesized voice reads them, and a video pipeline cuts them into short-form review clips. If students are scrolling anyway, learning can live in the feed too.

Minesweeper AI

An agent that clears Minesweeper boards using deterministic logical inference first, then probability estimates when certainty runs out. It outperformed 80 percent of participants in its course tournament.
