In order to meet customers’ demand for lidar products that combine range and high sensitivity with excellent cost performance, SLAMTEC leverages its technical advantages in triangular ranging & DTOF ranging to launch a new generation of fused DTOF radar products – RPLIDAR C1.

RPLIDAR C1 not only has the ability of triangular ranging radar to handle the details of close objects, but also has the excellent performance of DTOF in ranging distance, accuracy, anti-interference and anti-smearing, killing two birds with one stone.

Measuring distance: 0.05m-12m (70% reflectivity)

                 0.05m-6m (10% reflectivity)

Sampling frequency: 5KHz

Scanning frequency: 8-12Hz (Typical value: 10Hz)

Pitch angle: 0°-1.5°

Distance measurement accuracy: ±30mm

Anti-light intensity: 40Klux

HD fusion technology achieves millimeter-level accuracy

RPLIDAR C1 integrates SLAMTEC technical advantages accumulated over many years in triangulation ranging and DTOF ranging, and is deeply integrated.

1. Have a close-range detail experience comparable to trigonometric radar

Now, let’s use the most common big white wall scene to take a look at the measured details of RPLIDAR C1, A series radars, and traditional TOF ranging radars under close objects.

It can be seen that in terms of detailed experience of close-range objects, the performance of C1 is almost consistent with that of the A-series triangular radar, meeting customers’ needs for high precision and high details at close range.

2. Facing various environmental objects, excellent anti-tailing and anti-interference performance

In addition to excellent detail performance at close range, anti-interference and anti-tailing capabilities in the environment are also equally important for lidar. So, what is the actual measured performance of C1 and A series and traditional TOF lidar when facing objects that may cause tailing in the environment?

The picture shows the scene combination of white wall + paper cup. It can be seen that when C1 and A series radars face paper cups that may cause tailing, the point cloud diagram is clear, no tailing, and no adhesion occurs.

Stable surface accuracy when facing highly reflective objects

Stainless steel tables and chairs, skirting boards, fitness quick-drying clothes, etc. are common highly reflective object surfaces in daily life. However, if lidar is not capable of dealing with highly reflective objects, point clouds with unstable accuracy will appear, affecting use.

SLAMTEC RPLIDAR C1 has stable ranging accuracy without losing points when facing highly reflective objects, protecting applications such as mobile robots.

High resolution for small objects

When facing small objects, RPLIDAR C1 can “see” every detail in the environment clearly, highly restoring the scene, making the application more comfortable.

It can be seen that when faced with a table leg of only about 1cm, RPLIDAR C1 perfectly restored the details without artifacts, restoring the realism of the scene to the highest level.

High detection rate of dark objects

Due to the different reflectivity of various types of objects to light, the detection of dark-colored objects has always been a problem in the lidar community. So if dark objects + small objects appear in the same scene at the same time, will the test immediately escalate? Let’s see how C1 responds.

Among them, C1 is a red point cloud, and A series is a blue point cloud. Judging from the picture, the point clouds are almost the same, and they have perfectly withstood the test of the black +5mm forward convex reflector.

Enrich perception, not just flat surface

Thanks to the accumulation of SLAMTEC self-developed SL-DTOF ranging technology, in addition to feedback position information data, RPLIDAR C1 can also output reflectivity data and 2.5D multi-dimensional information to give you more reference.

Compact and easy to integrate, complete development kit

At the same time, C1 is small in size and easy to integrate, bringing more imagination space to customers’ applications.

In terms of integration performance, SLAMTEC provides customers with SDK development kits running on different platforms such as x86 Windows, x86 Linux, arm Linux, etc. It supports ROS and ROS2 operating systems to help customers develop and integrate on different operating systems and architectures.

High reliability, compatible with SLAMTEC ecosystem

RPLIDAR C1 is highly compatible with SLAMTEC software and hardware interfaces and ecosystem, and its size can also enable worry-free switching with SLAMTEC existing products.

SLAMTEC will continue to focus on lidar technology, use technology to develop and accumulate the market, and also exert its unlimited value to make robots and other applications walk smarter.
