Saras 2.0: a Raspberry Pi 4 rover that runs Claude Code as its brain
Tech With Anant rebuilt the Saras rover around Claude Code running on a Raspberry Pi 4. A small MCP server exposes the motors, encoders and camera as tools, and a CLAUDE.md file sets the robot's identity. An LD06 lidar handles obstacle detection. The 24-minute video shows the rover in a live test, driving toward a named object around obstacles.

servomotor-mcp: Claude Code drives Gearotons M17 RS-485 servomotors
Gearotons' servomotor-mcp drives its M17 closed-loop NEMA-17 servomotors over RS-485 from Claude Code. It auto-detects motors on the bus, wraps each of the 48 firmware commands as a tool and adds high-level moves; a mock backend runs without hardware. A terminal recording and a 50-second video show Claude Code turning a bench M17 and reading its encoder.

vibe-hardware: agent skills from idea to firmware, PCB and enclosure
vibe-hardware installs skills into Claude Code or Codex that take an idea to ESP32 firmware, a KiCad board, a build123d enclosure and a JLCPCB order. Its example is a desk pager on an M5StickC S3 that buzzes when a Claude Code session needs input. The README says the firmware works; the PCB and shell are still stubs.

Beee: an ESP32-S3 desk face where agents ask for a physical yes or no
Beee puts an animated face on a Waveshare ESP32-S3 touch screen that agents reach through an HTTP API or an MCP server. An agent can show moods and short text, or ask a question and wait until a person taps an answer. Critical actions get a flashing red border and a countdown. README photos show the face on the device.

Linutronix on the lab behind an agent that reserves, flashes and power-cycles real boards
Linutronix describes an off-the-shelf AI agent that tests embedded boards in its lab through a small MCP server. In the example session the agent reserves a board, flashes it, reads the console and power-cycles it after a bad flash. The post argues that the safety comes from the lab underneath. It shows one screenshot and no logs.

Espressif's notes on building a Zephyr BLE and SoftAP provisioning app with Cursor
Ricardo F. Tafas Jr of Espressif describes building Zephyr provisioning over BLE and SoftAP for the M5Stack ESP DualKey with Cursor. He tested each step on the bench through build, flash and UART traces. His practices include specs first, proving a module in a sample app, a journal of failed fixes and no edits to upstream Zephyr.

Project Fetch phase two: Claude Opus 4.7 in Claude Code writes the sensor code for a robot dog
Anthropic repeated its robot-dog experiment with Claude Opus 4.7 in Claude Code, a researcher approving each command. On every task a 2025 human team had completed, including connecting to the camera and lidar, Claude was at least ten times faster. Anthropic says its attempts to knock the beach ball back were poorly controlled, and it never finished the autonomous fetch.

Embedded Arena: agents deploy models to microcontrollers with hardware feedback
Zhihan Zhang and colleagues, mostly at the University of Washington, published Embedded Arena, a benchmark that scores agents' model and firmware edits on microcontrollers. Boards include a MAX78000, an ESP32-S3 and an STM32N6. The paper reports Claude Opus 4.7 and Gemini 3.1 Pro failing every deployment without hardware feedback; with it, the first success came within 3 iterations.
