What is the most efficient way to row a boat? Should all the oars pull simultaneously or out-of-phase? French researchers in Paris’s Laboratory of Hydrodynamics (LadHyX) explored this question by actually building arduino based robotic rowers.
At this point, everyone who has been part of a rowing team can breathe a sigh of relief, because even though the speed variations were reduced when the row bots were rowing asynchronously (thus reducing losses to fluid friction), the overall speed of the boat was reduced as well, and this proved to be the case for all asynchronous tests at any phase. Rowing together, in sync, really is the fastest and most efficient way of rowing.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
