Major automakers—along with upstarts such as Tesla and Uber—are racing to put self-driving cars on the road, leading to advances in enabling technologies such as laser range finders known as lidars. A lidar works like a hyperactive laser measure, scattering laser light in multiple directions to gather hundreds of thousands of measurements per second and build up a “point cloud” of spatial information. A computer processes these data to form a coherent picture of a vehicle’s surroundings.
Now a Pittsburgh-based start-up called Kaarta has integrated a lidar—more affordable and speedier these days, thanks to accelerated development by suppliers serving the auto industry—with a motion sensor, processor and seven-inch touch screen into a handheld device. Called the Contour, the device enables architects, builders and others to generate 3-D computer models of their surroundings on the fly as they walk through them, the company says. A camera on the device captures color data and maps them onto point clouds to render models in realistic hues. When loaded into standard computer-aided design (CAD) software, the models can then form the basis of building renovation plans or other projects.
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.
