Description
- 【First 3D obstacle avoidance function】 LD07 is the most sophisticated sensor for robotic 3D obstacle avoidance based on structured light technology, which is the first-invented in the industry. It has accurate detection performance for tiny objects and can detect the smallest 5mm small obstacles. Combined with the first-class algorithm, the obstacle avoidance ability is the best performance one.
- 【The 3D performance along the wall is excellent】 In terms of 3D along the wall, LD07 can cover 90° field of view Angle, which is much better than traditional PSD along the wall technology and realizes the distance along the wall less than 10mm.
- 【Ultra-thin & Coin size】 Using exclusive solid light technology, smaller size, lower power consumption, binocular camera FOV is up to 90 degrees. It can be installed on the front of the robot for accurate obstacle avoidance, and can be installed on the side of the robot for accurate edge-alone.
Product description
LD07 line structured light radar is a solid-state lidar is developed by Shenzhen LDROBOT Co., Ltd. This LiDAR can scan and measure visual point-cloud signal in 90 degree of laser scanning , be widely applied in map construction (SLAM), robot positioning and navigation device.
For robots device, LD07 has shown an excellent 3D obstacle avoidance and 3D edge-along ability, the angular resolution of LD07 LIdar can reach 0.5 degree at minimum, and recognize objects as small as 5mm in width; In terms of 3D edge along performance, LD07 covers 90 degree of viewing angle and can walk precisely along obstacles with height of 5mm at minimum. LD07 has greatly improved customer experience in minor obstacles recognition and avoidance ,as well as edge-along performance.

Communication and Interface
LD07 uses the ZH1.5T-4P 1.5mm connectors to connect with the external system to implement power supply and data receiving. The specific interface definition and parameter requirements are as following:
| No | Signal | Type | Description | Minimum | Typical | Maximum |
| 1 | TX | Output | UART TX | 0V | 2.8V | 3.63V |
| 2 | RX | Input | UART RX | 0V | 2.8V | 3.63V |
| 3 | VCC | Power | Power | 3.1V | 3.3V | 3.63V |
| 4 | GND | Power | GND | – | 0 | – |
The data communication of LD07 adopts standard asynchronous serial port (UART) for one-way transmission, and its transmission parameters are shown in the table below:
| Baud Rate | Data Bits | Stop Bits | Parity Bit | Flow Control |
| 921600 | 8 Bits | 1 | No | No |
LD07 is needed to send instructions to work normally. Please refer to “LDROBOT_LD07_ development manual” for detailed usage.
