Real-time operating systems

Comparisons and explainers on FreeRTOS, Zephyr, NuttX and other RTOS options, judged on determinism, licensing and toolchain maturity.

Microcontrollers and compute modules

Hardware coverage from Arm Cortex-M motor controllers to GPU-equipped edge boards, with honest notes on power, thermals and long-term availability.

Bridging firmware and ROS 2

How micro-ROS, DDS and serial links connect low-level firmware to higher-level robot software, and where those connections tend to break down.

Safety, testing and security

Practical guidance on watchdogs, functional safety standards such as IEC 61508, hardware-in-the-loop testing and secure over-the-air updates.
