A sakid, I loved robots. From Robbie the Robot and Metal Mickey to the Terminator and the robots from The Black Hole, if it had a CPU and a tendency to run rampant and threaten the destruction of the world, I was there. Now middleaged, my love of robots has never waned, but I would rather see them as companions than overlords bent on our destruction.
Robots are still awesome and over the past decade they have become easier and cheaper to create, largely thanks to the Raspberry Pi and Arduino. Building a robot is a right of passage for an aspiring maker. By building your own, you learn key maker skills: soldering, circuits and code. If you have the means and skills to do so, you can go DIY and build a fully custom robot from scratch, using laser-cut or 3D-printed parts. But if starting out, you can use one of the many kits available.
If you want a completely ready-to-go solution, Pimoroni’s Trilobot is an amazing kit. Using PCBs as the chassis, this kit integrates the Raspberry Pi 4 as a central part. It can work with ultrasonic sensors, linefollowing sensors and many others via the GPIO.
At the other end of the robotics scale are the advanced robots that use machine learning and artificial intelligence along with sensors and cameras to understand the world
