Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 Shown is the schematic diagram of the wheel-leg mechanism embodied in the present invention. Wheel-leg mechanism among the present invention comprises first power machine 104, second power machine 106, thigh 108, shank 110, toe 112, rotating disc 114, rope 116, hinged device 118 and a pair of torsion spring 120 of left and right rotation.

[0020] The first power machine 104 and the second power machine 106 are installed on the body 102 . Described thigh 108 comprises round wheel and femur, and the top end of described femur is fixed on the central rotating shaft of round wheel, and the end of femur is fixed on the circumference of round wheel, wherein the output shaft of first power machine 104 connects the femur At the top, the thigh 108 is controlled to rotate, forming the hip joint 122 .

[0021] The end of the femur and the top of the lo...

Abstract

The invention discloses a wheel and leg mechanism for a wheel and leg compound type robot.The wheel and leg mechanism comprises two power machines, thighs, shanks, toes, rotary discs, ropes, hinge devices and a pair of left-handed torsional spring and right-handed torsional spring.Through the cooperative control of the two power machines, the wheel mode and the leg mode of the robot can be switched, and the robot can correspondingly move in the two modes.According to the wheel and leg mechanism, the power machines are both installed on a machine body, and therefore legs are low in weight, and the influences of the rotating inertia of the moving legs on the stability of the robot are effectively reduced when the robot moves in the leg mode.According to the wheel and leg mechanism, the pair of torsional springs are added to knee joints of the legs, and the vibration caused when the robot moves in the leg mode and the toes hit the ground is effectively relieved.

Description

technical field [0001] The invention relates to a wheel-leg compound robot, in particular to a wheel-leg mechanism of the wheel-leg compound robot. Background technique [0002] In the event of fires, mine disasters, nuclear leaks, terrorist attacks and other events, it is often necessary to carry out dangerous tasks such as search and rescue, anti-terrorism, detonation, and reconnaissance. In order to reduce casualties, mobile robots are often used. Due to the complex ground environment with both flat and irregular terrains, there is a need for mobile robots that can move efficiently in both terrains. Wheeled robots can achieve fast and stable locomotion on flat ground, while legged robots can adapt to irregular terrain. In order to integrate the advantages of wheeled and legged robots, wheel-legged composite robots have become a hot spot in the field of mobile robot research. The existing wheel-leg composite robot wheel legs have complex structures and large masses, whi...
