Touch-sensitive steering for a RatCar
Reading Time: 2 minutesArduino Team — July 19th, 2022 Bears on tricycles aside, animals are not very good at piloting vehicles. But maybe that is because we haven’t given them controls that suit their thumbless bodies. If a vehicle had controls adapted to a particular animal’s anatomy, could they drive? Back in 2019, researchers at…
