Do a Google search on “build your own robot” and you’ll find a treasure trove of kits, articles, and videos. Have you ever wanted to give this a try? An engineer at Maxim with a long-standing interest in robotics found a way to build his own using one of the company’s featherboards. Presented with an opportunity to write some example code for the Bosch Sensortec BMI160 inertial measurement unit (IMU) on Maxim’s MAX32630FTHR board, the engineer jumped at the chance to build his own self-balancing robot.
Such robots must do alot of mathematical calculations. The engineer started his project by configuring the on-board IMU, which estimates a pitch angle from vertical to help the robot stay straight. Should the robot drift away from the vertical point, the control loop would direct the DC motors to keep the base of the robot under its center of gravity.
The MAX32630FTHR board is designed to help engineers quickly implement battery-optimized solutions with the MAX32630 ARM Cortex-M4F microcontroller. And Maxim’s featherboards are plug-in compatible with Adafruit’s Featherwing add-ons, giving a hundred different peripheral options in a snap.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
