D500 Development Kit STL-19P LiDAR ROS Robot Car TOF Laser Radar Mapping Navigation SLAM Support for ROS1/ROS2

Description:
- The STL-19P consists mainly of a laser ranging core, a wireless power transmission unit, a wireless communication unit, an angle measuring unit, a motor drive unit and a mechanical housing.
- With DTOF technology, STL-19P ranging core is able to perform 5,000 measurements per second. For each ranging, the LiDAR emits an infrared laser, which is reflected back to the single photon receiving unit when it encounters the target object. From this, we obtain the time at which the laser is emitted and that at which it is received by the single photon receiving unit. The time difference between them is the time of flight of the light, which can be combined with the speed of light to solve for the distance. Once the distance data have been obtained, STL-19P fuses the angle values measured by the angle measuring unit to form the point cloud data and then sends the point cloud data to an external interface via wireless communication. Meanwhile the external interface supports PWM input to enable the motor drive unit to drive the motor rotation. The external control unit obtains the speed and controls it to the specified speed by means of a PID algorithm in closed-loop control, thus allowing the LiDAR to work stably.
- The product is mainly suitable for the navigation and obstacle avoidance of robots (e.g. floor mopping robots and service robots) by performing a 360° scan of the indoor layout and building a map so that a walking path can be planned. It is also suitable for robotics education and research, etc.

Features:
- High ranging accuracy at close range, with a mean error of ±10mm over a distance of 0.03 to 0.5m.
- Compact footprint, easy to integrated design, guaranteeing the aesthetics of the product.
- High resistance to ambient light interference, for use in environments up to 60Klux.
- Supporting for glass wall detection.
- Stable performance with a lifetime of up to 10,000 hours.

Function:
- 360° scanning for ranging: The STL-19P LiDAR scans at 10Hz by default and measures distance at a rate of 5,000 times per second. Output of ranging information (including distance and angle data) for 360° surroundings via UART interface.
- PWM speed control: STL-19P is furnished with a stepless speed regulation motor drive and supports both internal and external speed control. When the PWM pin is grounded, the internal speed regulation is available by default, at the speed of 10Hz by default. External speed control requires a square signal to be connected to the PWM pin, which can be used to control the start, stop and speed of the motor via the PWM signal duty ratio. Due to individual differences in each product motor, the actual speed may vary when the duty ratio is set to typical values. For precise control of the motor speed, closed-loop control is required based on the speed information in the received data. (Notes: When external speed control is not used, the PWM pin must be grounded.)
- Glass detection: With multi-echo detection technology, the STL-19P supports glass wall detection (within ±5° of the angle of incidence and normal), reducing collisions during robot operation, extending the life of the whole machine and improving the user experience.
