The robot adopts track walking and remote control of the cabin. When the remote control robot moves to the designated position, the robot operates autonomously, collects surrounding sand in an orderly manner according to the set requirements, and loads the sand into the designated container. The distance between the shelter and the soil excavation site can reach up to 5km, using wireless video and wireless communication. Through three onboard videos and one third-party video, the operation site can be observed in all directions without dead spots. The robot has an automatic replacement function, and through the hydraulic wrist and the oil circuit in the accessory, the operator can efficiently replace the accessory in the cabin. In addition to the soil collection device, the robot is also equipped with various work tools such as hydraulic shears, hydraulic pliers, hydraulic material claws, hydraulic breakers, milling heads, and circular saws.
