🤖 40+ Free Robotics Sites — No Hardware Needed

:robot: The “I Can’t Afford Robots” Starter Pack

:high_voltage: Free Robot Simulators + MIT Courses — Full List

Every free website that turns your browser into a robotics lab. No hardware. No money. No excuses.


:world_map: What You’re Walking Away With

A complete cheat sheet of 40+ places to learn robotics without spending a single dollar on kits, parts, or courses.


:light_bulb: Why This Is Actually Insane

The robot kit you’re eyeing on Amazon? $200+. Breaks when you sneeze on it.

These websites simulate the exact same thing — sensors, motors, physics, code — for free.

You could mass-fail 10,000 times and never lose a cent. That’s how pros actually learn.


:sparkles: What You Get

  • :electric_plug: Build circuits that actually work (or explode harmlessly)
  • :mechanical_arm: Code robot arms to grab things like a factory worker
  • :automobile: Make wheels follow lines, dodge walls, navigate mazes
  • :brain: Train AI that controls robot movement
  • :factory: Get skills that actual job postings ask for
  • :video_game: Play with physics engines used in AAA games
  • :scroll: Earn certificates that don’t look like participation trophies

:prohibited: Skip These (Money Traps & Time Wasters)

Before we start — know what to avoid

Trap Why It’s Bad
$50+ “beginner” kits Break easily, can’t reset, limited projects
Paid courses under $100 Free alternatives exist and are often better
Outdated ROS tutorials ROS 1 is dying — learn ROS 2
“Learn robotics in 1 hour” YouTubers Clickbait. Real learning takes practice.
Anything requiring Windows XP Yes, these still exist. Run.
