Wheel-leg combined search and rescue robot platform

Abstract

The invention discloses a wheel-leg combined search and rescue robot platform. The wheel-leg combined search and rescue robot platform comprises a frame, pulling rods, a differential mechanism, synchronous belts, legs, a motor, a lithium battery, a steering motor, caterpillar bands, a triangular fork, a guiding wheel, caterpillar wheels, a worm gear reducer, belt wheels and crank wheels. Two belt wheel carriers are arranged at the front end of the frame, and each belt wheel carrier is provided with one crank wheel, one belt wheel and one synchronous belt; each leg is rotatably connected with one pulling rod and one crank wheel; the differential mechanism is installed at the front end of the frame, the motor is installed on the upper side of the frame, and an output shaft of the motor drives the four legs to move through the differential mechanism; the lithium battery is installed on the lower side of the front frame, and the steering motor and the worm gear reducer are installed at the rear end of the frame; a rotation shaft of the triangular fork and an output hole of the worm gear reducer are installed together, the two caterpillar wheels and the guiding wheel are installed at the lower end of the triangular fork, one caterpillar band is installed between each caterpillar wheel and the guiding wheel, and the steering motor controls steering of the robot platform.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a wheel-leg combined search and rescue robot platform. Background technique [0002] Since the 21st century, global natural disasters (such as earthquakes, fires, floods), terrorist attacks (such as explosions) and biochemical crises (nuclear leaks, toxic chemicals) have continuously threatened human security. Therefore, the rapid handling of these disasters and Emergency capability is very important. After sudden terrorist attacks, earthquakes, fires and other disasters, some large-scale house collapses and casualties may be caused. Therefore, on-site detection and search and rescue have become the work that people care most about. However, disaster sites are generally complex collapsed and dangerous ruin environments. It is difficult for search and rescue personnel and search and rescue dogs to enter some narrow and rugged gaps or pipes, so people can only carry out...

AI Technical Summary

Problems solved by technology

Snake robots are relatively small in size, and can use the torque generated by each joint to make the robot move in a meandering manner. It has flexible movement characteristics, but due to structural limitations, they are often only suitable for moving on relatively flat ground or in water; UAVs are mainly It is mainly suspended in the air to provide real-time information and transport materials through sensors, which does not play a key role in the search and rescue work in the ruins, and the impact of bad weather on drones is also relatively large; crawler search and rescue robots use crawler As its driving method, its driving ability is limited when facing a rough road with a large drop, which limits its ability to enter the ruins for search and detection, so its practical application has certain limitations
