    حضرة السيد مازن


    اريد دائرة 12vلزوم عربة يمكننا تشغيل محرك on off ويمين يسار لمحرك اخر على نفس الدائرة

    لنفس العربةنريد تحريكها على بعد 15سنتم عبر هذه الدائرة وبدون اي رابط اي ان العربة تلحق الدائرة

    على مسافة 15سنتم بدون رابط من فضلك


    وللتوضيح اكثر اريد وضع قطعة اليكترونية على الخصر تتحكم بتشغيل العربة حسب تنقل الشخص

    على مسافة 15سنتم اذا ابتعدت المسافة لسبب ما ينطلق زمور اشارة منبه

    اريد تصنيع نموذج واحد وفي حال تمت الموافقة سيكون هناك طلب لكميات اخرى

    فاذا كان لديك استعداد للموضوع ارجو الرد بالسرعة القصوى

    هل يستطيع احد ان ينفذ لي هذه الد ائرة حسب المطلوب

    JavaBot1...........
    A line following robot. by James Vroman

    Design Goal:
    The JavaBot1 is a small line following robot designed to follow a black line drawn on a dry erase board. It is designed to follow very tight curves. The software still has lot's of room for improvement but works well as is.

    Motive Power:
    The JavaBot1 uses 2 Cirrus CS-70 servos that have been modified
    for full rotation and have had their controller boards removed to
    convert them from servos to gear motors.
    Servos are a common motive power for small robots due to their
    low cost, ready availability, standardized sizes and the fact that it
    only requires 1 bit on your processor to control the motor.
    We initially tried this approach but found that the speed control was
    very minimal with a finer control needed for this application. The
    servo controller boards were then removed and the wires soldered
    to the motor terminals and case ground. The motors were then
    controlled by an H-bridge circuit to allow direction and speed control
    with only 2 processor bits per motor. This is implemented as one bit for
    direction and another bit for power/speed control per motor.

    Sensors:

    In order to follow the line I/R reflective sensors were used to
    detect if a line was present or not. The sensors chosen are the
    QRB1114 from QT Optoelectronics and have a focal point of
    about 1/4 inch. They are available from DIGI-KEY.
    Most line followers use 2 or 3 sensors of this type to do their
    detection. This works but does not give the ability to follow
    lines with very tight turns. An array of seven sensors arranged
    in an "inverted V " patternare bolted under the front of the robot
    The sensors are wired with all the receivers connected in parallel and
    fed to an LM311 comparator to set the threshold trigger level with it's
    output fed to a processor bit. The transmitter LEDs are connected
    to a 74HCT138 with a current limiting resistor to VCC. This allows
    the entire array to use 4 bits for the sensors.

    Processor:
    The PIC16F84 was chosen for it's small size, easy reprogramability
    and interrupts ( the fact that we manufacture a PIC processor
    emulator also helped in this decision). It is clocked at 4 MHZ by
    a ceramic resonator and is powered by 4 AA rechargeable batteries.
    These same batteries power the motors. This is usually not recommended
    since surges in motor current can affect the processors operation, but with
    decoupling caps in place and the watchdog timer being used in the
    software no problems were experienced. The watchdog could reset the
    processor if it went stupid before you could ever see it act up.

    Mechanical:


    The servos were modified for full rotation by disassembling the servo
    to gain access to the gear compartment. The main gear is then removed
    and the stop that keeps it from rotating removed with an hobby knife.
    The plastic key that keeps the feedback pot hooked to the main gear is
    removed to allow full rotation without moving the feedback pot. The
    servo controller was removed and the feed back pot removed as well.
    The wires were removed from the control board and resoldered to the
    motor terminals. The servos were reassembled and taped together.
    This assembly was then attached to the bottom with the standoffs that
    held the line follower board in place. For this application the circuitry
    was split into a sensor board and a processor/h-bridge board. The two
    boards were connected by a ribbon cable. The entire assembly could
    be built on one circuit board with the same board being used as the chassis.
    The sensor board is mounted under the front of the chassis with
    the processor/motor control board above. A skid (plastic knob )
    is attached to the rear of the robot.

    The battery holder is mounted over the skid to keep the weight
    to the back and counterbalance the line sensors .
    The drive wheels are model airplane aluminum, racing wheels and are bolted to the
    servo horns with #2 bolts. Both the Dallas Personal Robotics Group
    and the Seattle Robotics Society have more information on
    modifying servos for use in robotic applications.

    Firmware:
    The firmware for JavaBot1 is based on the code written by
    Jerry Merrill for the TechBot1.
    The program is divided into 3 sections - The main program loop,
    The pwm isr ( pulse width modulation interrupt sub routine) and
    The action routines. The program functions to turn on the
    transmitter portion of the sensors in order of priority and see
    if a line is seen by the receiver section. The outer sensors are
    tested first. If a line is seen then one motor is reversed while
    the other continues forward. If no line is seen the next set in
    are checked. If a line is seen here then one motor is stopped
    while the other continues forward. If no line is seen here then
    the next set in is checked. If a line is seen here then the speed
    of one motor is reduced while the others speed is maintained.
    If no line is seen by these sensors then the centermost sensor
    is checked. If a line is seen here then the motors are set for
    both full forward (we reduced this from full speed for better
    reliability). If no line is seen by this last sensor than the last
    motor setting is maintained in hopes of finding the line again.
    Once a sensor detects a line and sets the motor settings then
    the sensor routine is started again. In this manor priority is
    given to the outermost sensors for the biggest corrections
    with the more minor corrections being serviced last. More
    details on this can be seen in the code listing. The firmware
    was developed using the ClearView Mathias PIC emulator
    and assembler which can be downloaded for evaluation
    from HTTP://www.tech-tools.com

    What's next?
    The firmware could be updated to give more decision
    capability and a memory of the corrections. If the robot
    gets off course and intersects a line with both outside
    sensors it can sit there and oscillate till a sensor clears
    the line. A search capability that if the line is not seen
    in a certain period of time it can run a search pattern
    to locate the line would be a good addition.
    Add a speaker or sound effects chip. Robots
    that make noise get far more attention than ones that do
    not. The recovered I/O lines could be used for more sensors
    or as a buss to talk to other processors.
    Only your imagination will limit you.
