Computer Engineering, Boston University, Class of 2027

I design, build, and ship hardware, from the circuit board to the factory floor.

I'm Arav Tyagi. I co-founded Technotonin and spent five years taking a patented medical device from a first prototype to an overseas manufacturing line. I work across embedded firmware, mechanical design, and robotics.

Featured work

Technotonin Industries

Co-Founder, Co-CEO and Lead Engineer / May 2021 to May 2026

Technotonin makes PAWE, a lightweight attachment that turns any manual wheelchair into a joystick-driven electric wheelchair. It clips on in seconds, comes off just as fast, and fits in a car trunk. Power wheelchairs are heavy and expensive, and PAWE gives people powered mobility with the chair they already own.

I co-founded the company in high school with Antonio Marzoratti and led a team of seven. My work covered the product end to end: mechanical design, firmware, manufacturing, FDA strategy, and fundraising.

Engineering

  • Invented and built the quick-release attachment and the dual-motor friction drive that powers the wheelchair's own tires.
  • Wrote the C++ firmware: real-time control loops, joystick input, USB serial communication between controller and drive unit, failsafes, and watchdogs.
  • Closed the loop with motor encoders and an IMU for smooth acceleration and straight-line tracking.
  • Designed the controller and main electronics PCBs.

Manufacturing

  • Designed the full assembly for manufacturing in Onshape and produced machine shop drawings.
  • Set up an overseas manufacturing line and managed suppliers in China directly, including on-site visits in Shenzhen.
  • Iterated through multiple prototype generations using feedback from 100+ wheelchair users.

Regulatory and IP

  • Worked with patent counsel and the patent office to secure US Patent 12,605,293.
  • Drafted and submitted an FDA Q-Submission, and worked with FDA advisors and the FDA to classify the device and define its testing plan.

Business

  • Raised $200k in non-dilutive funding.
  • Won the CEO Global Pitch Competition (2024) and joined the VentureWell E-Team Program.
  • Reached early paying customers and signed letters of intent.

Experience

Embedded Systems Engineer

HVAC sensing company, Norwood, MA / Jan 2026 to Aug 2026

  • Wrote new C firmware for PIC-based HVAC sensor boards shipped worldwide, including CO₂ and particle conversion kits.
  • Designed new particulate and hygrometer sensor units that cut cost and improved quality and longevity.
  • Built MFC desktop applications to manage a suite of sensors, plus a GUI for the new particle sensor and supporting tools for hardware development and testing.

Current projects

What I'm building now

AI robot arm

A robotic arm that combines computer vision, voice interaction, and imitation learning to do tabletop tasks. A Gemini layer turns voice commands into task plans and turns images of the scene into 3D objects in a MuJoCo simulation for training, testing, and sim-to-real transfer.

Augmented reality mirror

A smart try-on mirror for clothing retail that displays clothes over your real reflection on a two-way mirror. I programmed the pose estimation, rendering, parallax correction, depth camera pipeline, and interface.
