    Tumbler, tin etc.

    Guess the weight of the load will come to less than a 100 grams.
    Next thing will be the max dia, of your load. This will determine the length of the 'fingers.'

    If you have complete manual control, you can make a gripper with one toy geared motor, and preferably, acrylic. You will need the basic tools like a cutter, junior saw etc. You can use 4mm/5mm acrylic. The total cost will come to may be less than 250.

    there are lot of designs with one motor.

    Now, if you are looking at something which stops gripping when it holds the load, you will need good sensors. You will need to measure the current of the motor as well. Here, cost goes up. forget 750. Dynamic gripping is way too difficult.

    Servos will give you better control, at the expense of program code. YOu have to get the timing right.

    I suggest you go for loads with less diameter. Saves you torque, and size.
    Grippers are tricky. They are not easy, but will be fun to work with. Once you have worked with end effectors, you will really appreciate the robotic arms that pack, seal, and catch a ball off air.

    hi,
    yesterday i found gripper online

    it is made up of two servos parallel to each other by a distance of 5 to 10 cm.
    and each servo had a metal strip with rubber at the end.
    it was easy to make.

    i will post some pictures of it when i complete the hardwares and softwares

    thank you everyone for the help

    Two servos on the gripper?? Just a thought but wont that put a lot of weight on the rest of your arm? Difficulty and feasibility are two completely different things. Hope you dont end up wasting your time.

    You do not need two motors for a gripper. It is better if you do it with one. It is cheaper, and more efficient than with two, unless in special cases.
    Less electronics, less control variables.
