Abstract

The invention provides a water-skipper-imitated water sports robot, and relates to the field of bio-robots. By the water-skipper-imitated water sports robot, the problem that a gliding state and a jumping state of the existing water robot cannot be freely switched over is solved. The water-skipper-imitated water sports robot comprises a rack, two direct-current motors, a worm wheel and gear speed-reduction assembly, a hinge pin, a cam assembly, a driving leg, a spring and a supporting leg, wherein the rack has a symmetric structure; the two direct-current motors are symmetric along a central axis of the rack; the worm wheel and gear speed-reduction assembly comprises a worm, a worm wheel, a first gear, a second gear, a third gear, a fourth gear and a fifth gear; the hinge pin comprises a first rotating shaft, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, a fifth rotating shaft, a sixth rotating shaft, a supporting shaft, a rotating shaft and a connecting shaft; the cam assembly comprises a first cam base, a rotating body and a cam top cover; the driving leg comprises a cam connecting rod, an ear-shaped connecting piece, a driving leg rod and a driving leg foot; and the supporting leg comprises a first supporting leg rod, a first supporting leg foot, a second supporting leg rod and a second supporting leg foot.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a robot capable of gliding on water surfaces and jumping continuously. Background technique [0002] At present, the development of bionic robots has involved various fields. In the development of surface robots, various bionic robots have appeared. Water striders, as a kind of aquatic insects that can move flexibly and freely on the water surface, have received extensive attention. There have been many related research results at home and abroad, such as: floating bionic water strider robot (public number: CN1911730A) and a bionic water strider robot (public number: CN102556318A), but jumping is still difficult to achieve in the current research work One point, at the same time, there is no robot that can freely switch between gliding and jumping states, and the restrictions on the movement trajectory of the legs of the water strider robot can also make the robot move closer to the ...
