RPLIDAR S1 360° TOF Laser Range Scanner

The RPLIDAR S1 is the next generation low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 9200 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.

The system can perform 2D 360-degree scan within a 40-meter range. The generated 2D point cloud data can be used in mapping, localization and object/environment modeling.

Compared with RPLIDARs in other series, RPLIDAR S1 has a more stable performance when detecting objects in long distance, objects in white or black alternatively and objects under direct sunlight, which is ideal for map building in the outdoor environment within a 40-meter ranging radius. Therefore, it can be widely applied in many consumer-oriented business scenarios.

The typical scanning frequency of RPLIDAR S1 is 10Hz(600rpm), and the frequency can be freely adjusted within the 8-15Hz range according to the specific requirements. With the 10Hz scanning frequency, the sampling rate is 9.2kHz and the angular resolution is 0.391°.

Due to the improvements in SLAMTEC hardware operating performance and related algorithm, RPLIDAR S1 works well in all kinds of indoor environment and outdoor environment with direct sunlight. Meanwhile, before leaving the factory, every RPLIDAR S1 has passed the strict testing to ensure the laser output power meet the eye-safety standard of IEC-60825 Class 1.

RPLIDAR S1 360° TOF Laser Range Scanner Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    Is it possible to buy just a replacement Interface Cable for Sensor to USB Interface Connection?

    • santaimpersonator / about 4 years ago / 1

      Unfortunately, we do not have just the cable available; you can try reaching out to the manufacturer.

    Advice from an owner of previous Slamtec products. This is a Chinese product with little or no support. Open up the SDK manual and note the requirement that the software only works with "Visual C++ 2010" which of course is not available legally. Even if your your bittorrent ninja skills allow you to obtain a copy the demo software either doesn't compile or compiles with many errors. I managed to get the demo running (it dumps a few times before bringing up the UI) but folks on the "support blog" haven't even got that far. Unless you like reverse engineering hardware this is a waste of money for those of us trying to use it in application scenario. No support. Truly dysfunctional software / SDK.

      As someone who has been using this device for several months, I should probably mention that their SDK supports not only Windows and Linux (including the RPi and Jetson Nano), but MacOS. Development is pretty easy. You receive frames of data describing the distance measured for each sample, along with the angular position, over a regular serial interface. The dongle included is just a USB to serial interface, which I personally don't use. Their github is here:
