2) RTAB-VSLAM 3D Vision Mapping and Navigation:
Supporting 3D color mapping in two ways, pure RTAB vision and fusion of vision and Lidar, JetHexa is able to navigate and avoid obstacle in 3D map and execute global relocation.
3) Multi-point Navigation and Obstacle Avoidance:
Lidar can detect the surroundings in real time, and let JetHexa avoid the obstacles during muti-point navigation.
4) Depth Image Data, Point Cloud Image:
Through the corresponding API, JetHexa can obtain depth image, color image and point cloud image of the camera.
5) KCF Target Tracking:
Based on KCF filtering algorithm, the robot can track the selected target.
6) Depth Camera Obstacle Recognition:
With the help of depth camera, it can detect the obstacle ahead and pass through the obstacle.
7) Custom Path Prowling:
User can customize the path and order the robot to prowl along the designed path.
8) Lidar Tracking:
By scanning the front moving object, Lidar makes robot capable of target tracking.
9) Lidar Guarding:
Lidar accounts for the role in guarding the surroundings and ringing the alarm when detecting intruder.
10) Color Recognition and Tracking:
Skilled in color recognition and tracking, the robot can be set to execute different actions according to the colors.
