The areas this project works through.

These four overlap constantly — a motor needs a driver, the driver needs a control loop, and the loop needs firmware to run it. Each is a thread of write-ups, tools, and open code that grows as the work does. Below is what sits under each one.

Robotics & Motion Control

Choosing and driving motors, closing the feedback loops around them, and the mechanics that carry the load — from a single actuator to a multi-axis machine.

  • Stepper / BLDC / brushed DC drives
  • Encoders & position feedback
  • Mechatronic & CAD integration

Power Electronics

Gate drive, converters, and switching stages that move power into motors and inductive loads within their electrical and thermal limits.

  • Gate driver & bootstrap design
  • Buck / boost converters
  • Si / SiC / GaN switching stages

Controls & Communication

Control loops from current to position, and the buses and bridges — CAN, SPI, RS-485, and Holoscan Sensor Bridge — that connect motors, sensors, and hosts.

  • Current / velocity / position loops
  • CAN, SPI, I2C, RS-485, UART
  • Holoscan Sensor Bridge
  • Sensorless & sensored control

Embedded Systems

The firmware and tooling underneath it all — bare-metal drivers, hardware bring-up, and the test rigs that keep the rest honest.

  • Bare-metal & RTOS firmware
  • Bring-up & hardware validation
  • Production test & automation tooling
