The invention belongs to the technical field of robots, provides a variable-form wheel foot mechanism and a robot, and aims to solve the problem that a leg type structure of an existing agricultural robot is easy to wear. The robot comprises a thigh part, a shank part and a supporting part which are rotationally connected in sequence, the thigh part is provided with a space for containing the shank part, the shank part can rotate along the thigh part and is contained in the thigh part, and the thigh part is provided with a driving wheel used for wheel type movement. The thigh parts are further provided with supporting rods capable of stretching out and drawing back in the length direction of the thigh parts. According to the leg type structure, the stress of the leg type structure during extension and contraction can be reduced, abrasion to joints of the leg type structure is reduced, the leg type structure can keep high-precision movement for a long time, and then the working stability of the whole robot is improved.

The invention discloses an amphibious robot with a wheel direction adjusting capability and a leg type structure for assisting obstacle crossing. The chassis is used for supporting the whole structure of the robot; a front leg mechanism and a rear leg mechanism are respectively mounted at the front end and the rear end of the chassis; two front wheel vertical rotating mechanisms and two rear wheel horizontal rotating mechanisms are symmetrically mounted at four corners of the bottom of the chassis respectively; the two front wheel vertical rotating mechanisms and the two rear wheel horizontal rotating mechanisms are respectively connected with two damping wheel mechanisms; the amphibious robot has the advantages that the amphibious robot can work in the amphibious environment, obstacle crossing can be assisted through the front legs and the rear legs on the land, efficient sliding can be achieved on the water surface, and the direction can be flexibly controlled.

The utility model discloses a connecting rod wheel leg advancing mechanism. The angle between the thigh crank and the shank crank of the robot is changed through the screw rod mechanism, the lifting of the driving wheel and the driven wheel is controlled by combining the four-bar mechanism, and the free switching of two advancing modes of wheel type advancing and leg type advancing can be realized only through the driving of the screw rod motor. In the leg advancing mode, the mechanical feet are independently used instead of wheels to make contact with the ground, the situations such as slipping are avoided, and the more stable advancing effect is achieved; in the wheel advancing mode, double wheels of the knee joint and the ankle joint make contact with the ground, and stability and anti-interference performance are enhanced. The robot is suitable for stable and rapid advancing in complex terrains such as gardens.

The utility model discloses a gear mechanical wheel leg advancing mechanism. The leg movement of an animal is simulated, the transmission between the legs is carried out through the toothed chain transmission mechanism, the bending of the shank crank is controlled, and the control of the thigh and the sole is combined, so that the walking in the complex terrain of the garden is completed; meanwhile, leg wheel conversion is completed through a toothed chain transmission mechanism, rapid and stable movement on a flat road surface / grassland is achieved, energy consumption for frequently controlling leg movement is reduced, and mechanical maneuverability is improved. During leg type advancing, wheel type contact with the ground can be avoided, and stable advancing on the soft ground or the gravel ground can be achieved. The device is simple in structure and easy to realize, and can be matched with different instruments to improve the flexibility and maneuverability of the machinery.
