Gobot — Robotics and IoT Framework for Go

Introduction

Gobot is a Go framework that provides a consistent API for interacting with hardware devices, robots, and IoT platforms. It abstracts away platform-specific details so you can write device-control logic once and run it across Arduino, Raspberry Pi, drones, and many other platforms.

What Gobot Does

• Provides drivers for GPIO, I2C, SPI, and serial communication protocols
• Supports 40+ hardware platforms including Arduino, Raspberry Pi, BeagleBone, and Jetson Nano
• Integrates with drones (DJI Tello, Parrot), Sphero robots, and Leap Motion controllers
• Offers an event-based programming model with timers and callbacks
• Includes an optional HTTP API for remote-controlling robots over the network

Architecture Overview

Gobot is organized around three concepts: Adaptors (platform connections), Drivers (device interfaces), and Robots (units of work). An Adaptor handles the low-level connection to a board or protocol. Drivers use the Adaptor to communicate with specific hardware (LEDs, motors, sensors). A Robot groups connections, devices, and a work function into a runnable unit. Multiple Robots can be managed by a single Master.

Self-Hosting & Configuration

• Install with go get gobot.io/x/gobot/v2 — pure Go core, platform packages are separate
• Connect to Arduino via Firmata protocol over serial USB
• For Raspberry Pi, use the built-in GPIO adaptor with direct memory-mapped I/O
• For drones, install platform-specific packages like gobot.io/x/gobot/v2/platforms/dji/tello
• Optionally enable the built-in API server for HTTP and WebSocket remote control

Key Features

• Unified API across dozens of hardware platforms and protocols
• Event system for reacting to sensor data, button presses, and device state changes
• Built-in support for MQTT and BLE for wireless IoT communication
• Composable architecture — combine multiple robots into coordinated swarms
• Full concurrency support using Go goroutines for parallel device control

Comparison with Similar Tools

• Johnny-Five (JS) — similar abstraction for hardware; Gobot brings Go's concurrency and type safety
• Arduino IDE — C/C++ firmware development; Gobot controls Arduino from Go over Firmata
• ROS — full robotics middleware; Gobot is lighter and focused on device-level control
• TinyGo — compiles Go to microcontrollers directly; Gobot runs on the host and controls devices remotely

FAQ

Q: Does Gobot run on the microcontroller itself? A: No, Gobot runs on a host machine (PC, Raspberry Pi) and communicates with devices over serial, I2C, GPIO, or network protocols.

Q: What Go version is required? A: Gobot v2 requires Go 1.18 or later.

Q: Can I control multiple devices simultaneously? A: Yes, each Robot runs concurrently. You can manage multiple Robots in a single program.

Q: Does Gobot support computer vision? A: It has an OpenCV integration for camera access and image processing.
