Question 1

How do I set up Gobot with a Raspberry Pi?

Accepted Answer

Cross-compile your Go code for ARM using environment variables like GOOS and GOARCH, transfer the binary to the Pi, and use examples like raspi_blink.go from the repository. Ensure you have the correct GPIO permissions and drivers installed.

Question 2

What's the difference between Gobot and ROS?

Accepted Answer

Gobot is a Go-specific framework focused on hardware abstraction and simple APIs for IoT and robotics, while ROS is a comprehensive middleware with tools for simulation, perception, and navigation, but primarily supports C++ and Python.

Question 3

Can Gobot control multiple robots at once?

Accepted Answer

Yes, using the 'Manager' approach shown in the examples, you can add multiple robots to a manager instance and control them via the built-in API server for swarm operations.

Question 4

Is Gobot good for drone programming?

Accepted Answer

Yes, it supports drones like DJI Tello and Parrot models through dedicated packages, but you'll need to implement flight logic and sensor handling manually, as it provides low-level control.

Question 5

How to handle errors in Gobot code?

Accepted Answer

Gobot uses Go's standard error handling pattern; functions return errors that should be checked and managed, as demonstrated in the examples where errors are printed or cause panics.

Question 6

Can I use Gobot without installing the full framework?

Accepted Answer

Yes, the 'Metal' mode allows using pure Go with minimal abstraction by importing only necessary packages for direct hardware control, avoiding the full robot lifecycle management.
