    How to make your first ROBOT:


    For those whom are a bit tight on cash. I converted the Robot to a cheaper version. I.E no need for servo motor, no need for  a distance sensor.

    Is it is not automonous anymore But it is a start and can easely be converted back to the orginal again, when more cash is available.

    This robot is infrared controlled. I.E, It makes the same moves, but it is controlled with a remote. Wich is a fraction of the cost compared to a distance sensor and servo motor combination.

    Happy building.

    I am planning to build a robotic arm with 6 to 8 servos and the arm has to be quite strong.I want to buy servos which have high torque but the servos should be cheap and reliable.So do you guys have any suggestion where can i find such servos ?

    Thanks in advance

    I have been using arduino IDE (023 and 1.0) on windows XP without any problem but whenever i use arduino IDE on windows 7 64-bit it doesn't work as it should.If i click on any of the options like "File,Edit,Sketch,Tools,etc" it freezes for few seconds or sometimes even for a minute.Its kind of irritating when you want to test the code many times.So i was wondering that any of you experiencing same problem and if yes did you find any solution for it(other than switching the OS)?

    I don't know if anyone has done this before, I'm sure someone must have tried it, but I can't seem to find any information on Google.


    What I've done so far, is remove the gears and motor from a servo, attach the motor leads to another motor with gearbox, than attach the servo's pot to the new gearbox's output shaft, so I can get positional information from this gearbox.

    I've been constructed the circuit exactly the same as yours. All items are exactly the same. The program downloaded to the board successfully. The servo also functioning well before connected to the circuit and after discarded from the circuit (use testing servo code). Meanwhile, the gear motor also funtion properly when connected straight to battery.Unfortunately, nothing happen to the robot.

    Hi. Gyus.


    This is my first time to build device.

    I saw the example of programming for device.

    I am building simple device but I don't know how to do progamming.


    If The track is that that

    1. 300mm forward and turn right 90 degree

    2. after that 1000mm  forward and turn right 90 degree

    3. and then 200mm forward and turn left

    4. and 1000mm forward and the device has to stop.


    If some people have good idea or programming for that, please send an email to me.
