Episode 134: Robotics as a hobby - Kevin McAleer

Robot Talk · 21 Nov 2025 · 37m · Episode 134

What this episode covers

Kevin McAleer, founder of Kev's Robots, explains how he transitioned from a computer science background to building hobbyist robots using 3D printers, Arduino, and MicroPython. He details his educational projects, including the Smars robot, Haybot, and Bubo, which utilize components like Raspberry Pi Pico, ultrasonic sensors, and OpenCV for computer vision. McAleer discusses the accessibility of modern robotics tools, such as Tiny Tapeout for custom silicon and affordable sensors from suppliers like Waveshare, while highlighting the challenges of selling kits due to Brexit tariffs. He also reflects on the current state of humanoid robotics, noting the gap between pre-choreographed demonstrations and the complex reality of general-purpose manipulation and safety.

    383: The Monkey's Not Gonna Work

    Mario Marchese, known as Mario the Maker Magician, discusses his unique intersection of robotics and traditional magic, detailing how he builds accessible, cardboard-based robots like Automabot to inspire young makers. He explains the engineering challenges of synchronizing multiple circuits for illusions like the Coin Matrix and shares how he turned technical failures, such as a snapped ground wire on his robot monkey Marcel, into entertaining features of his live show. Marchese also covers his book 'The Maker Magician's Handbook', his work with Piff the Magic Dragon, and his philosophy on using accessible tools like Arduino and 3D printing to lower the barrier to entry for creative technology.
