Make invisible gravitational waves, radio waves, sound waves, etc., graspable and more comprehensible with AR (Augmented Reality) robotics using a simple device I invented at the age of 12, in 1974. This device is so simple that a child can build it, yet by combining it with robotics, it can provide a true 3D augmented reality display that does not require any special eyeglasses to see.In this Instructable we'll take this simple device, which is simply linear array of light sources that disp...

Students use ultrasonic sensors and LEGO© MINDSTORMS© EV3 robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in order to improve the…
