  • Sample Frequency: 2000 - 8000 Hz

The RPLIDAR A2 360° Laser Scanner is the next generation of 360 degree 2D lidars. The RPLIDAR A2 adopts low cost laser triangulation measurement system developed by SLAMTEC, and therefore has excellent performance in all kinds of indoor environments and outdoor environments without direct sunlight exposure.

It can take up to 8000 samples of laser ranging per second with high rotation speed. And equipped with SLAMTEC patented OPTMAG technology, it breakouts the life limitation of traditional LIDAR system so as to work stably for a long time.

RPLIDAR A2 360° Laser Scanner

The system can perform 2D 360-degree scan within a 12-meter range. The generated 2D point cloud data can be used in mapping, localization and object/environment modeling.

Before leaving the factory, every RPLIDAR A2 has passed  strict testing to ensure the laser output power meets the standards of FDA Class I.

The typical scanning frequency of the RPLIDAR A2 360° Laser Scanner is 10hz (600rpm). Under this condition, the resolution will be 0.9°. And the actual scanning frequency can be freely adjusted within the 5-15hz range according to the requirements of users.

RPLIDAR A2 360° Laser Scanner

The RPLIDAR A2 consists of a range scanner core and mechanical powering parts which makes the core rotate at a high speed. When it functions normally, the scanner will rotate and scan clockwise. And users can get the range scan data via the communication interface of the RPLIDAR and control the start, stop and rotating speed of the rotatation motor via PWM.

RPLIDAR A2 360° Laser Scanner

The RPLIDAR A2 comes with a rotation speed detection and adaptive system. The system will adjust the angular resolution automatically according to the actual rotating speed.

Review by GRISSEL

The Lidar is easy to setup, to program, and have good support for ROS

(Posted on 5/14/18)

Good Lidar!

Review by B.N.

The Lidar is easy to setup, to program, and have good support for ROS. It has its own package already in ROS, so it is easy as ABC :)

Super easy to use, no complaints

Review by Rhys

Easy to setup and use with ROS. I originally was going to complain about the lack of mounting options, but after double checking there are several threaded mounting points available.

I've seen several people complaining about price, however, this unit is actually fairly cheap in comparison with many other lidar units available these days.

Good lidar

Review by Nick

Its pricey but- I tried the competition and it was hardly usable half the rate and cheap slip ring. this guy seems pretty solid with no slip ring to wear after a randomly short amount of time. I have only tested functionality but this seems better than advertised!

Good Quality Lidar

Review by Subhash

Good quality Lidar, double the data rate over predecessor, RPLidar A1, but cost is also double. Price could be lower.

Powered up and connecting super easily

Review by Benjamin

One of the easiest ROS installs I've done. Within about half an hour, I had a visualization of the sensor data up and running in RVIZ.

Easy to use

Review by Puwanan

Good quality. Running on normal Ubuntu (14.04, 16.04): the available libraries make it easy to use with ROS and my custom cpp software. Running on Jetson TX2: you need to build the USB kernel first, then you will see ttyUSB0 on your TX2.

Review by Hamid

Purchased >30 Pcs. All worked good. Price is still a bit to high.

Worked Well

Review by Thomas

Easy to interface with ROS. Had some difficulties setting it up on a Nvidia TX1, but that was due to the USB to serial driver. Worked like a charm otherwise.

As expected

Review by F

Meets expectations

useful sensor

Review by Pavel

Seems to work well. Every revolution of the sensor leads to a slightly different number of readings, but angular information for each reading is provided. The output includes also the quality information about each ray. Contains easy to understand examples in C++, it was easy to use and integrate into our raspberry-pi based project, although, we have cut the cable to solder an extra power line to our 5V power source, since raspberry pi USB is not supposed to provide that much current as is needed on startup.

Great product, be careful not to break usb plug

Review by James

Works as advertised. USB adapter board is a bit fragile and you can't order a new one separately.

Awesome Product

Review by Mark

A very neat piece of kit. Accurate and simple to set up. I've connected mine to a Raspberry Pi running ROS. The ROS drivers worked pretty much out of the box (after compiling). Works brilliantly with SLAM (gmapping & Hector)

Does what it says

Review by Raptotype Ltd.

Great product, is easy to set up and performs really well.

(Posted on 2/9/17)

Awesome Product!

Review by Superhands

Perfect product for all applications. Highly Recommend!

(Posted on 1/18/17)

Good, Nice package, windows

Review by Superhands

Really nice product together with beautiful package. Running well, although needed some extra efforts to run on Win32bit vs Win64bit.

Great Sensor

Review by Victor

Best bang for your buck for indoor applications. Rotates smoother than it's younger brother (RPLidar 1) and feels much more solid.

Best quality price sensor

Review by braykeh

very good quality price sensor, very accurate in indoor applications with a range of 5-6 meters , light weight and easy to use

Review by SHM

Very easy to use and works perfectly fine

(Posted on 12/20/16)

Works well, easy to use. Great quality for the price.

Review by Nick

Works out of the box with my Dell XPS15 running Ubuntu 14.04. It was very easy to get running with ROS.

It offers a far less noisy output than the ZED stereo camera which currently is the same price. Although it only scans a one height.

It did not work out of the box with the Jetson TX1 also running Ubuntu 14.04. I'm still trying to troubleshoot the issue.

Reported Weight is Shipping Weight. If you're an engineer you should be fuming...

Review by Chris

Don't fret ladies and gents, this beautiful sensor actually weighs 195 grams. It Weighs 200 grams when you connect the small power board. It only ever weighs 350 grams inside the box with all the documentation and packaging. I am currently using this sensor for my Undergraduate Design Capstone on a Solo 3DR Drone for local obstacle avoidance.
