THE WORK, UP CLOSE

Built across disciplines.

Real project material, with the context
behind each system.

01COMPUTER VISION & AUTONOMOUS TRACKING

SKYLOCKSeeing the bigger picture.

Military-grade project

From remote control to full autonomy.

SKYLOCK is a military-grade system that brings camera feeds, computer vision and control hardware together. It was developed in two phases: first for remote operation, then for fully autonomous drone tracking.

  • Computer vision
  • Autonomous tracking
  • Remote operation
  • Embedded systems

PHASE 1 / THE FIRST ITERATION

SKYLOCK v1

The first system paired physical hardware with a custom operator application, built so SKYLOCK could be controlled remotely. These development materials document that prototype.

02WEARABLE AI & ACCESSIBILITY

    Autonomous navigation on a predefined map, with remote control when needed.

  2. 02
    Engage naturally

    Face tracking, expressive displays and responsive conversation.

  3. 03
    Build for different settings

    A modular platform for reception, guidance and human–robot interaction research.

  • Autonomous navigation
  • Face tracking
  • Modular robotics

From development to interaction.

INTELLIGENT PROSTHETIC HAND

A human problem.
An integrated response.

ReFlex explores how a prosthetic hand can respond to both its wearer and the object in front of it. The research prototype combines a flexible, tendon-driven hand with muscle-signal sensing, embedded vision and feedback from its motors.

  1. 01
    Sense intent

    An EMG sensor reads forearm muscle activity to initiate movement.

  2. 02
    Understand the object

    A palm-mounted camera and trained vision model inform grip selection, including pinch and tripod grips.

  3. 03
    Respond with feedback

    Encoder feedback tracks finger movement and supports controlled stopping.

  • Raspberry Pi 5
  • TensorFlow Lite
  • Sensor fusion

THE ENGINEERING CHALLENGE

Bring intention, perception
and movement into one system.

The challenge was to coordinate several kinds of input while building a hand with a flexible, human-like form. ReFlex connects the mechanical design, embedded electronics and control software in a working laboratory prototype.

01 / FABRICATION
Start with a softer structure.

TPU 95A 3D-printed fingers use string-driven actuation. A custom forearm sleeve houses the assembly, bringing the wearable structure and the hand together.

02 / EMBEDDED VISION
Choose a grip from visual context.

A custom-trained MobileNetV2 model runs through TensorFlow Lite on a Raspberry Pi 5. The palm camera supplies the object view used to select a suitable grip.

Pi Camera · MobileNetV2 · TensorFlow Lite
03 / CONTROL
Keep sensing and motion connected.

The control pipeline combines EMG input, camera data and encoder feedback. Motor commands and position feedback coordinate the fingers through the grip cycle.
