This easy-to-build walking reindeer can be constructed with only a bow motor, battery, wires, and a few other parts.

This library is to use L9110 motor driver. The L9110 is a simple motor driver which only allows forward or reverse. For this it uses two pins of which only one can be HIGH. If both are LOW or both are ...

This study presents a synthetic jets cooling device with silicon-based piezoelectric MEMS actuators. The device, with an area of 100mm2 and driven by 5V, can generate synthetic jets with an air ...

The Arduino UNO R4 brought a modern 32-bit platform to the classic UNO form factor, adding higher voltage tolerance, USB-C, a Renesas RA4M1 MCU, and a long list of robustness upgrades. The WiFi ...

Abstract: Rigid robots can achieve precise motions but expose shortcomings in system complexity, fabrication cost, and human–robot interaction, which motivates researchers to develop various soft ...
