32 results about "Self direction" patented technology

A moving apparatus has a body, and has at least a pair of wheels, a control unit, a direction measuring unit and at least a pair of encoders installed on the body. The direction measuring unit coupled to the control unit measures the direction of the body, and the control unit obtains a first direction variation according to the direction information. The pair of encoders coupled to the control unit measure a speed of the pair of wheels, and the control unit obtains a second direction variation according to information of the speed. The control unit compares the first and second direction variations to determine whether the direction measuring unit is temporarily dysfunction. Based on the result of comparison, the control unit applies the information provided by the direction measuring unit or the pair of encoders to obtain the current direction of the body.

The invention provides a 3D printing method and equipment. The 3D printing method comprises the steps that height groups of a to-be-printed object in multiple different poses relative to a supportingplatform is obtained, wherein the different height groups comprise the heights of the to-be-printed object in at least one direction corresponding to the different poses; the smallest first height inthe height groups is obtained, and the second height and the third height which are orthogonal with the first height are obtained according to the first height, wherein the second height and the thirdheight are the smallest heights in the self directions; and the directions where the first height, the second height and the third height are located are used as three printing directions of the to-be-printed object for printing. The high printing speed can be achieved.

The invention relates to a U-shaped slideway facility capable of achieving headstand playing and belongs to the field of playing facilities. The U-shaped slideway facility comprises a U-shaped slideway, a rolling device and a headstand plate, wherein the rolling device comprises three rolling wheels, connecting shafts and a rotatable shaft; the headstand plate comprises a leg fixing strap, hand rods, a waist fixing strap and shoulder retaining plates. The working manner of the U-shaped slideway facility includes: a person lies on the headstand plate, the legs of the person are fixed by the leg fixing strap, the waist of the person is fixed by the waist fixing strap, and the shoulders of the person is exactly abutted against the lower portions of the shoulder retaining plates; the person dives downwardly in a headstand posture, the rolling device rolls up onto a high-platform slope at the other end and rolls downwardly again, the headstand plate rotates to allow the head of the person to dive downwardly, finally inertia weakens, and the headstand plate stops in the middle of the U-shaped slideway; during the upward rolling and downward rolling of the rolling device, the person can hold the hand rods and use leg strength to rotate the headstand plate so as to constantly change self-directions. The U-shaped slideway facility is simple in structure, high in fun, widely applicable to various people and capable of achieving a body building effect.

The invention belongs to the related technical field of intelligent control, and discloses a control system for a wheeled robot to automatically walk along a slope center line, which comprises a slopeedge identification module, a target distance identification module, a slope inclination angle identification module, a central controller, a self-adaptive slope inclination angle driving module andthe like. Wherein the slope edge recognition module is used for detecting the slope edge and correspondingly calculating the deviation between the current position of the trolley and the slope centerline, so that the trolley can adjust the self direction to walk along the slope center line; the slope inclination angle recognition module is used for detecting the inclination angle of the robot trolley, and correspondingly, the parameters of the driving module can be configured to enable the trolley to stably run on a slope; and when the trolley approaches the target place, the stop position mark is detected through the target distance identification module, and the trolley can be accurately controlled to realize deceleration parking. By means of the method, effective guarantee can be provided for the wheeled robot to stably crawl along the center line of the slope and accurately stop at a destination.

The invention provides a mixed mode flexible feeding system, which is used for automatically feeding parts for n flexible production lines via a central distribution region, wherein n is not less than 2. The system includes a controller, the central distribution region, a signal device, n material boxes respectively corresponding to the n production lines, n self-direction vehicles respectively corresponding to the n material boxes, a material sorting region, a material box inlet region and a material box outlet region, wherein the central distribution region includes a material box confluence passage comprising an inlet section, a material sorting section and an outlet section; the material sorting region includes a material rack with a plurality of part storage positions; n inlet distribution passages corresponding to the n material boxes are arranged in the material box inlet region, and are all connected to an inlet section of the material box confluence passage; multiple material boxes enters from the inlet distribution passages queue up at the inlet section of the material box confluence passage and then enter the material sorting section of the material box confluence passage sequentially; and moreover, n outlet distribution passages respectively corresponding to the n material boxes are arranged in the material box outlet region, and are all connected to an outlet section of the material box confluence passage. The invention further provides a corresponding mixed mode flexible feeding method.

The invention discloses a double directional antenna neighbor discovering method based on antenna rotation speed difference. The method includes: equipping each node with the same direction antenna and allocating the unique identification ID for each node; calculating the number N of scanning directions; by one node preparing to transmit information, starting a neighbor discovering process, increasing the rotation speed of the self direction antenna to N times of that of an idle node, and transmitting neighbor discovering messages; by neighbor nodes receiving the neighbor discovering message, transmitting reply information; by the discovering node receiving the reply information, saving neighbor information and judging whether the discovering process is finished or not. The method has the advantages that the advantages of the directional antennas are fully utilized, the neighbor discovering node can rotate a circle to transmit the neighbor discovering messages to N directions when the directional antenna of one optional neighbor node points at the discovering node by increasing the rotation angle speed of the self direction antenna, and all the neighbor nodes can receive the neighbor discovering messages.
