RPLIDAR C1 development kit includes the matched tools used for evaluating

RPLIDAR’s performance and initial development. After connecting the RPLIDAR

C1 with PC via USB cable, users can observe the cloud map of the environment

scanning point collected by the RPLIDAR in RoboStudio and start development

based on the SDK.

Items in the Development Kit

RPLIDAR C1 Development Kit contains:

The RPLIDAR C1 development kit contains standard RPLIDAR C1. The drivable

motor controller can be used to configure the scan frequency by tuning motor

speed. Developers can also choose to turn off the motor for power saving

purpose.

RPLIDAR usage and interface definition will be introduced in the coming

sections.

Connection

RPLIDAR C1 can be easily connected to PC according to the following steps.

1) Connect RPLIDAR C1 with the USB cable.

Figure 2-1 Connect RPLIDAR C1 and USB cable

2) Connect the USB cable to your PC via the Micro-USB cable. If the PC is on,

after connecting the USB cable to your PC, the indicator light of the USB

will light up but the RPLIDAR will not start scanning.

Figure 2-2 Connect the USB cable to PC via Micro-USB Cable

Install Driver for the USB cable

The USB cable converts UART to USB by using CP2102 chip. You need to install

the device driver for the chip. The driver can be found in the provided SDK

package or downloaded from Silicon Labs’official website:

http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

Connection and Usage

6/ 16

Here’s the installation steps in Windows: after connecting the RPLIDAR with PC,

please find the driver file “CP210x VCP Windows” and choose correct operating

system version accordingly: x86 for 32-bit OS and x64 for 64-bit OS.

Figure 2-3 Choose USB cable Driver for Installation

Figure 2-4 Start Page of USB cable Driver Installation

After Installing the driver according to the above installation steps, you will see

corresponding serial port name in the [Control Panel] -> [Device and Printers].

Please refer to the below figure.

Run Demo Application

SLAMTEC provides a Lidars plugin in RoboStudio for users in test and evaluation.

You can view the scan result directly in the UI and save the scan result to files for

further processing.

This GUI demo can only run under Windows. For Linux and MacOS users, please

refer to the other simple demo provided in the SDK.

Please make sure you have connected RPLIDAR to PC by using USB cable and

installed the device driver correctly before running the demo application in

RoboStudio. Launch RoboStudio and log in.

Figure 2-6 RoboStudio Login Page

If the connection is ok, you shall see the user interface is shown as below.

1. Click File->Lidars to open the lidar control panel in the left;

2. Click Serial Ports to extend the lidar lists and you’ll find the RPLIDAR C1

previously connected to your PC;

3. Click the RPLIDAR C1 icon to extend the tool buttons below the icon: the left

one is to adjust the motor speed while the right one is to open the tool bar in

the major work area as shown in Figure 2-7.

The serial number, version and model of the RPLIDAR C1 will show next with its

icon in the lidar control panel. The supported commands of RPLIDAR are

showed in the tool bar. The descriptions are listed in the bellow table.

Figure 2-8 The Supported Commands of RPLIDAR in RoboStudio

Press the Start Scan button , the scan data will be displayed as below (by

default, the motor rotating speed should be 10Hz.):

Figure 2-9 The Scan Outline by RPLIDAR in RoboStudio

Right click in the major working area to choose a range so as to zoom in or out

the view.

The scan frequency is also showed in the above interface.

Troubleshooting

When the scan core or the laser power works abnormally, the scan core will

enter protection mode. This state can be retrieved via SDK API. If such scenario

happened, please send restart command to reset the scan core.

Motor Speed Adjustment

During the running process, different motor rotating speed can be achieved by

pressing the button, which can fit in different working environments or meet

specific requirements. There will be a speed adjustment dialog box and dash

board popped up for users to enter required speed. After entering a value, the

motor will work as the settled rotating speed automatically. User can also drag

the sliding handle to the required rotating speed.

The current actual rotating speed will show in the upper left corner of the major

work area. For instance, the actual rotating speed in the following screenshot is

10.02Hz.
