A robot-adopting explosive hydraulic compound fracturing drilling and completion system for hot-dry rocks comprises a ground control system, a robot, a drilling execution system, an explosive fracturing execution system, a hydraulic fracturing execution system, a directional execution system and a reentry execution system. The ground control system comprises a data processing center, a ground dataacquisition sensor, a well drilling completion controller, a ground signal transmitting-receiving device, a blowout preventer, a continuous oil pipe well mouth device, a continuous oil pipe operationtruck, an input device and a storage unit. The robot comprises a well bottom data acquisition sensor, a CPU, a drilling control module, a well bottom signal transmitting-receiving device, a reentry tool control module, a directional tool control module, an explosive fracturing control module and a hydraulic fracturing control module. By adopting the robot technology, intelligent closed-loop welldrilling is achieved, the operation cost is effectively reduced, a burning explosion and a hydraulic compound fracturing technology are adopted, a hot-dry rock fracture network can be remarkably optimized, and the risk of 'heat transfer short circuit' is reduced.
