Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of robot movement-control system, comprise Myo armlet, signal receiving end, single-chip microcomputer, motor/steering engine controller and motor/steering wheel, Myo armlet is connected with signal receiving end by bluetooth, and signal receiving end is connected with motor/steering wheel with single-chip microcomputer, motor/steering engine controller successively.Described signal receiving end is computer, smart mobile phone or panel computer.Described Myo armlet is provided by Thalmic company.
Utilize this device to carry out the method for motion planning and robot control, comprise the steps:
Step (1): be worn on arm by Myo armlet, detects the acceleration signal of arm motion, attitude signal and electromyographic signal by Myo armlet;
Step (2): the signal data that Myo gathers is transferred to computer or smart mobile phone or panel computer by bluetooth;
Step (3): signal data, by the SDK coding of Myo armlet, is resolved and is reduced into the hand signal of user by computer or smart mobile phone or panel computer;
Step (4): hand signal is sent to single-chip microcomputer by computer or smart mobile phone or panel computer;
Step (5): single-chip microcomputer and sensor and motor or steering engine controller are connected, and go to control motor or steering wheel motion, reach the object of control.
The Myo armlet also produced by Thalmic company designs, it comprises 1 nine axle inertial sensor unit, 8 surface myoelectric sensors and a Bluetooth Receiver.Wherein nine axle inertial sensor unit are for detecting arm motion track and orientation, and surface myoelectric sensor is for detecting arm electromyographic signal during different gesture, and Bluetooth Receiver is used for the data communication of Myo and controller.Described robot comprises one and comprehensively turns to four-wheel drive chassis and a lifting structure.Machine people has been the hardware condition of control action, and chassis driving wheel is made up of four steering wheels and four DC brushless motors, and lifting structure is made up of two linear electric motors.
Described Myo armlet is by being connected with controller with bluetooth, and controller is connected with motor by relay, be hand signal and inertial sensor signal be motor message, and then control completes the motion of predetermined action finally by decoding electromyographic signal.
Workflow of the present utility model is introduced below by accompanying drawing 1.
Described Myo armlet, comprise 1 nine axle inertial sensor unit (three axis accelerometer, three-axis gyroscope, three axle magnetometers) and 8 surface myoelectric sensors, nine axle inertial sensor unit can detect athletic posture and the acceleration signal of arm, the electromyographic signal of arm when machining surface electric transducer can detect palm and finger motion, and then change into the signal of telecommunication.
Then by bluetooth, above-mentioned arm attitude signal, acceleration signal, electromyographic signal are transferred to computer or mobile phone or panel computer, the SDK of the Myo armlet provided by Thalmic company, these signal decodings are reduced into corresponding hand signal by coding.Set 5 kinds of hand signals (right hand is example) in the present embodiment, as shown in Figure 2, they are respectively middle finger and thumb is double-clicked, clenches fist, opened hand, and palm is brandished left, palm is brandished to the right.
After the procedure identification in computer/mobile phone/panel computer goes out corresponding hand signal, corresponding hand signal can be sent to single-chip microcomputer by wireless or Bluetooth function (computer can adopt data wire to connect) by mobile phone/panel computer, single-chip microcomputer is different according to the hand signal received, control motor and steering engine controller respectively, and then go control motor or steering wheel to go to realize different motion modes.For the artificial example of four-wheel exercise machine, when double-click gesture being detected, represent the people that starts the machine; When a hand gesture being detected, representing and advancing; When detect a left side wave gesture time, represent turn left; When detect the right side wave gesture time, expression bends to right.When detect clench fist gesture time, represent stop robot motion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
