AWS launches open-source Physical AI Toolchain for robotics
An open-source set of tools for training, simulating and testing robot AI models, a sign of how much robot learning now happens in simulation.

A learning path into robot engineering.
Robot engineering mixes mechanics, electronics and software. You do not need all three on day one; you need a path, a few good projects, and the habit of writing down what you learn. This is that path, in order.
The path, in order
Each step builds on the last. Spend a few weeks on each and finish at least one small project before moving on.
Basic circuits
Voltage, current and resistance. Read a schematic, use a multimeter, light an LED without burning it out.
A microcontroller
Write simple programs: read a button, blink a light, print a value. Learn to debug by printing.
Motors, servos and sensors
Drive a motor through a driver board, position a servo, read distance and light sensors.
Kinematics
How joint angles move a tool through space. Start with a two-joint arm on paper.
Control
Feedback loops: measure, compare to a target, correct. Tune a simple controller until it stops overshooting.
Practice projects by level
Projects teach what tutorials cannot: what happens when real parts behave badly.
| Level | Project | What it teaches |
|---|---|---|
| Starter | Line-following robot | Sensors, simple decisions, and why lighting matters. |
| Starter | Obstacle-avoiding rover | Distance sensing and stopping in time. |
| Intermediate | Two-joint drawing arm | Kinematics and servo accuracy. |
| Intermediate | Balancing robot | Feedback control and tuning. |
| Advanced | A robot that maps a room | Odometry, sensor noise and combining measurements. |
Words worth learning early
- Degrees of freedom
- The number of independent ways a robot can move.
- Encoder
- A sensor that reports how far a motor has turned.
- PWM
- Pulse-width modulation, the usual way to control motor speed and servo position from a microcontroller.
- Inverse kinematics
- Working backwards from where you want the tool to be to the joint angles that get it there.
Learn in public
Document each build with photos, a parts list and notes on what went wrong. It will help you remember what you learned, and a clear record of real projects shows what you can do far better than a list of courses.

How pressure sensing in a gripper helps a robot tell whether it has a stable hold or a part that is starting to slip.
