A kind of Intelligent self-balancing traffic robot
Technical field
Relate to a kind of robot at the utility model, particularly a kind of can automatically realize before and after and left right balanced traffic robot, belonging to can be owing to the vehicle of riding instead of walk.
Background technology
The development of the land crafts such as bicycle, motor bike, automobile except the application of power resources and material, does not have larger breakthrough in principle so far.Self-Balancing vehicle has been broken traditional Thought, for new road has been opened up in birth, development and the application of the new vehicle.Utilize gravity force energy, can provide more actv. technical solution for people carry out safe, steady, green transportation on land.
At the end of last century, American inventor Di grace. toll bar (Dean Kamen) is invented the personal transport carrier that has designed a kind of driven by power, had the homeostasis ability with his team of DEKA research and development company (DEKA Research and Development Corp.), can allow people ride that its is mobile without barrier at city the inside milli, and be referred to as " thinking car ".The inventive concept of thinking car is to be based upon on " dynamic stability " groundwork (DynamicStabilization), namely based on the self-equalizing ability of vehicle itself.Judge the residing posture state of vehicle body with built-in accurate solid-state gyroscope (Solid-StateGyroscopes), see through accurate and after central microprocessor at a high speed calculated suitable instruction, CD-ROM drive motor was accomplished the effect of balance.
Structure on the thinking car comprises four large major parts: wheel and powerplant module, sensing system, computerized control system and operator control system.Main sensing system is one group of gyroscope, by the constant characteristic of the direction of utilizing gyroscope to have to keep its S. A. indication the attitude data of thinking car is carried out accurately data acquisition.The thinking car is equipped with 3~5 gyro sensors, in order to finish degree of dip and the inclination degree of surveying front and rear direction.Because the system of thinking car is complicated, and need to adopt a plurality of gyroscopes, manufacturing cost is high, has also significantly increased the cost of the maintenance of its software and hardware simultaneously.
