Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of micro walking robot and driving method thereof are provided, the present invention is simple in structure, processing and manufacturing is with low cost, be convenient to realization, can very in narrow space, realize continuously rectilinear motion fast, adapt to multiple different surface characteristic, and the larger load force of output.
The technical scheme that the present invention solves its technical problem employing is: a kind of new micro walking robot and driving method thereof, comprise front end, rear end, guide rail, body and linear stepping motor.Linear stepping motor is fixed in the motor slot of body, and linear stepping motor output shaft is exported axial trough by body and formed and coordinate with front end motor axial trough and rear end motor shaft groove, the motion of straight limit stepper motor output shaft; Front-end and back-end are fixed together by two elongated guide rails; Guide rail is formed and coordinates with body by body guide-track groove, the direction of motion of constraint body; After front end cilium, rear end cilium is separately fixed at the bottom of front-end and back-end, plays anchor point effect in the motion process of microrobot.
The invention has the beneficial effects as follows: the present invention has adopted lumbricoid cyclic drive scheme, is the continuous unlimited formation campaign of robot by the short range reciprocating conversion of motion of miniature linear.Compare with other robot drive scheme, of the present invention simple in structure, be conducive to the reduction of batch machining and cost.Meanwhile, the drive scheme that the present invention adopts makes this robot can effectively adapt to multiple different topography and geomorphology, also can obtain higher power output and objective output speed by high performance linear electric motors.The technical advantage of this small scale robot, makes him can obtain in following field of medical good application prospect.

The specific embodiment
As shown in Figure 1, the present invention includes front end 5, rear end 1, body 3, guide rail 6 and motor body 4 and motor shaft 2.Wherein, motor body 4 is arranged in body motor slot 8, and motor shaft forms and coordinates with body motor axis hole 9, front end motor axis hole 12 and rear end motor axis hole 14; Guide rail 6 forms and coordinates with body guide-track groove 7,11He rear end, front slideway hole guide rail hole 13; Front end cilium 17, rear end cilium 15 and body cilium 16 are arranged on respectively corresponding front end 5, the bottom of rear end 1 and body 3.
As shown in Figure 2, described body 3 basic structures are square shape.Body 3 both sides are processed with body guide-track groove 7, for fixed guide 6; Its inside is processed with body motor slot 8 and body motor axis hole 9, for fixed electrical machinery body 4 and motor shaft 2.Body cilium 16 is cementing in body 3 bottoms.
As shown in Figure 3, described guide rail 6 is elongated cylindrical bars.
As shown in Figure 4, described linear stepping motor comprises motor body 4 and motor shaft 2.
As shown in Figure 5, described front end 5 basic structures are square shape.One end of front end 5 is processed with two guide rail holes 11 and a motor axis hole 12, is respectively used to the unidirectional spacing of guide rail 6 and motor shaft 2; Front end cilium 17 is arranged on the bottom of front end 5.
As shown in Figure 6, described rear end 1 basic structure is square shape.One end of rear end 1 is processed with two guide rail holes 13 and a motor axis hole 14 is respectively used to the unidirectional spacing of guide rail 6 and motor shaft 2; Rear end cilium 15 is arranged on the bottom of rear end 1.
As shown in Figure 7, the microrobot of the present invention's design adopts the motion principle of class earthworm.During original state, miniature linear is in non-driven state (Fig. 7 (a)), front end cilium 17, and rear end cilium 15 and body cilium 16 are all in non-erectility; When miniature linear starts, along a direction, move, motor shaft 2 travels forward with respect to motor body 4.Under the effect of this relative motion, body cilium 16, in erectility, stop body 3 to move, and front end cilium 17 and rear end cilium 15 is all in non-erectility, do not affect the motion of front end 5 and rear end 1.Like this, front end 5 and rear end 1 one end distance that travels forward; When miniature linear changes rotation direction, along contrary direction, move, motor shaft 2 moves backward with respect to motor body 4.This relative motion impels front end cilium 17 and rear end cilium 15 in erectility, makes front end 5 and rear end 1 transfixion.On the contrary, body cilium 16 recovers non-erectility, does not affect body 3 motions.Like this, body 3 segment distance that travels forward.In this process, body 3, front end 5 and rear end equal 1 segment distance that travelled forward.Finally, whole robot returns to original state.So move in circles, this robot can travel forward continuously.According to this motion principle, the present invention can realize continuous rectilinear motion with conventional micro-step motor, and controllability is good, and output torque and output speed can meet the demand of a large amount of microrobot application.Meanwhile, the present invention possesses good expandability, by integrated more functional unit, can complete more task, realizes more function.
The above-mentioned specific embodiment principle of the present invention that is used for explaining, rather than limit the invention, in the protection domain of spirit of the present invention and claim, the modification that the present invention is made and change, all fall into protection scope of the present invention.
