LiDAR technology at the time and now

LiDAR technology at the time and now -

LiDAR (Light Detection and Ranging) technology was used in Apollo 15 lunar mission at the time. The technology has been around since 1960 and at the time it was filled with huge scanners occupying airplanes. In addition to this, it cost hundreds of thousands of dollars. However, over time, technology has decreased in size and cost, making it easy to fit in intelligent devices. Currently, it is used for surveying, mapping for geological research and archeology.

How LiDAR work? The technology uses a scanner to shoot infrared lasers that reflect or bounce off the solid material on the surface. The measured distance is then used to create a 3D image that then be interpreted by a computer system and based on this information, it will help the camera to take a certain decision that pre-coded instructions.

LiDAR technology has evolved. Today, technology is capable of being used for police speed gun to measure vehicles that exceed the speed limit. Another use of the technology is running the Cheetah robot, a robot with four legs 70 pounds, developed at MIT and funded by the Agency for Defense Advanced Research Projects (DARPA). The robot can run about 13 mph on a flat course. It was later upgraded to be able to jump over obstacles as it was programmed to be able to calculate the size, time and distance. Therefore, using this information, it is able to jump smoothly at the right time without human assistance at all. It is reported that the robot is able to jump about 18 inches high, more than half of its height during the race 5 mph.


Harvest HV-100 Automation (Harvey) is another example of LiDAR use. Harvey is programmed to be able to identify its location and determine where to place plants that are thousands of them in number and avoid obstacles on the way. In this way, farmers will be able to optimize space while minimizing labor costs and preventing worker injuries due to repetitive tasks.

LiDAR is also used in the next self driving vehicles in the navigation system.

Unfortunately there is a way to trick a LiDAR. To do this, the person must be at least 300 meters away from the device that uses technology using a specially modified laser pointer. The impact of this action is seen in the automotive industry in which a hacker is able to do a self-driving car swerved or stop by convincing the sensor there are some objects in front of them where in reality there is no object there. However, there are ways to counter this piracy by identifying and eliminating outliers from the raw LiDAR data.

Deloitte believes that the robots sales market for the handling of logistics, packaging and materials will double by 2020. Apparently, all these industries are using LiDAR and this year it is estimated at $ 18 billion.
