tello-engine

Engine created in Go to control a Tello drone using Gobot, with Lua as a scripting language. Yet another fun hackathon project.

Installation

go get -u github.com/eleniums/tello-playground

Install MPlayer for video:

brew install mplayer

Run

First, connect to the Tello drone via Wi-Fi. It will be named something similar to "TELLO-XXXXXX". Then run the program:

go run ./cmd/lua/main.go ./scripts/basic.lua

For a pure Go, non-scripted experience, run:

go run ./cmd/go/main.go
