Is your favorite robot currently in a mid-life crisis? Does it need a new purpose or perhaps, direction? Well now you can find your way with the affordable and easy to use Slamtec RPLIDAR A1.
You may have heard of LIDARs when people talk about self-driving cards. A LIDAR is a sensor that can detect distance precisely, using a laser. Unlike Time-of-Flight sensors, LIDARs are incredibly fast. Unlike sonar/ultrasonic sensors, they’re very precise, measuring the point exactly ahead.
Now, because you can get accurate distance measurements at high speeds, you can put the LIDAR sensor on a spinning motor. The laser shoots out thousands of times a second, and when correlated with the angular location, can create a 2D ‘map’ of obstacles and walls. Normally, LIDAR sensors are outside the budget of hobby/maker robots, but the Slamtec is a great price and is an excellent choice for many robots or interactive projects.
This laser scanner development kit can perform 360-degree scans within a 12-meter range. You can configure it for 2-10 Hz sample rate (that’s for an entire rotation). Out of the box you’ll get 0.2cm distance resolution, 1 degree angular resolution and 12 meter range.
