The Jueying X20 can delve into both outdoor and indoor natural disaster areas where it can negotiate ruins, rubble piles, stairwells and other unstructured paths; it can also easily climb obstacles and steps over 20 cm and climb slopes of 35 degrees. With its ability to move freely in all directions and maneuver within a small contact area, the robot dog can reduce secondary crashes. An industrial-grade IP66 rating allows the four-legged robot to carry out detection operations in extreme weather conditions, including heavy rains, sand and dust storms, low temperatures and hail. With a maximum payload of 85kg, the robot dog can carry oxygen tanks and other rescue supplies to disaster areas, making it easier for victims and rescuers to help. By integrating a wide range of application modules, including a long-range communication system, a dual-spectrum PTZ camera, a gas detection device, an omnidirectional camera, and a robotic arm, the robotic solution achieves long-range control and image transmission. heat source detection, real-time detection of harmful gases and emergency calls, and many other functions. In addition, Jueying X20 is available with an optional rotating laser scanner that can generate a high-precision point cloud representing indoor and outdoor disaster and accident sites, which is a reliable source of information for post-disaster data analysis.
