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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
