    Yes, you can control it using wireless· RF Modules.· We have the Key Chain remote control RF modules that will perfect for this.· Here is a link for the Key Chain RF modules:· http://www.parallax.com/html_pages/products/communication/rf_modules.asp make sure to scroll down to the 413MHz receiver and Key Chain transmitter.·· The Gripper uses a standard servo, basically it uses the PULSOUT command to control the servo.· Therefore, you can·set up your BASIC Stamp to revceive a SERIN command·to read each button press and·this will allow you to control the Boe-Bot and Gripper.

    The Gripper kit does not contain the microcontroller, you need to purchase that separately.· There are a few ways to do this and of them will require a transmitter and receiver.· You can use the eb500 Bluetooth modules with and eb600 and the Boe-Boe or you can use a second BASIC Stamp with an RF Transmitter connected to the PC and an RF Receiver on the Boe-Bot.··Here is a link for the RF and eb500 modules.· If you need sample codes please e-mail me at dandreae@parallax.com and I will send them to you.·

    Ayah -

    The gripper kit is an accessory, just like many accessories that Parallax already sells. Accessories are intended as "add-on" parts to an already existing, or planned electro-mechanical platform. Since I can only guess how its motion mechansim actually works, just take the following as one way that it MIGHT work, NOT that is DOES WORK this way.

    I've seen a number of gripper accessories which use an R/C servo as the motion mechanism. Therein, with a PBASIC Stamp you issue ordinarly PULSOUT commands to open and close the "fingers". The PBASIC Stamp is mounted on the central platform, and not on the gripper accessory itself.

    This is NOT to say, that some other microcontroller. CPU, or other quasi-intelligent or programmable device, other than a PBASIC Stamp, might be the "brains" issuing the appropriate commands to effect the R/C servo movement, by issuing the appropriately timed pulses and any necessary pauses. as may be·required for the R/C servo to move. The method used to operate R/C servos via timed pulses and appropriate pauses is well documented on the Internet.

    Regards,

    Bruce Bates

    Hello,

    ·· For a fully-functional Robot with Gripper you would need the following items:

    BOE-Bot Full Kit:

    http://www.parallax.com/detail.asp?product_id=28832

    Gripper Add-On:

    http://www.parallax.com/detail.asp?product_id=28202

    And if you need wireless, check this link for Bluetooth...

    What are you trying to do? Do you want a mobile robot with a gripper that can drive around and pick up objects, or are you looking for the gripper to be stationary (fixed to a table). If you want a robot that moves, the BOE-Bot Full Kit will give you everything you need except for the Gripper. It is the BEST way to get started on this. It will give you the Robots! curriculum that teaches you everything you need to get started. It is a great deal.

    Then you need a bunch of stuff:

    The robot base, wheels, motors, battery holder, etc. are what makes up the "bot" part of the BOE-bot.

    The Basic Stamp, and protoyping board make up the "BOE" part of the BOE-bot.

    The full·BOE-Bot kit gives you everything that you need to have a programmable mobile robot platform.· It includes a great teaching guide as well.

    Once you master·the programmable mobile robot platform, you can then move on to·more advanced things like grippers,·etc.

    You mean that to create a robot "move+grip+wireless" I must purchase a full BOE-Bot then for make it gripper must purchase the Gripper kit, then to make it wireless must purchase a bluetooth or RF modules

    OR

    get the gripper kit then get PBASIC stamp to make the gripper "move and grip"??

    The Gripper is the mechanical equivalent of a hand. without a body/arm and a brain, it doesn't do a whole lot. The BOE-BOT chassis would function as the body/arm and the BOE would function as the brain.

    Ayah, think of it this way:

    The BOE (with a stamp on it) is the brains.
    The bot is the legs.
    The gripper is the hand.
    And the wireless module is the walkie talkie.

    If you want all of these functions you need to get the BOE-bot, gripper and wireless module.

    If you don't want it to move around, you dont need the bot part and you can just buy the BOE and youll have a stationary "hand" that opens and closes when the wireless module tells it to.

    If you dont want to grab things, you don't need the gripper, and you'll have a mobile bot that can move according to the wireless module.

    If you don't want remote control of the bot, you don't need the wireless module, and you'll have a bot that can move around and grab things according to the program stored in the BOE.

    The only thing nessesary in all circumstances is the BOE (brains).

    Your fundamental confusion indicates you noviceness (nothing to be ashamed of, we all get our start sometime), but it would be best for you to learn how to walk before you attempt to run. Before investing all the money into buying everything and quickly getting in over your head, I would suggest you first buy just the BOE-bot. Follow all the exercises that come with it and get yourself familiarized with how it works. Then once you've done that, buy either the gripper or the rf-module then learn how to integrate that with the BOE-bot, then finally purchase the last component and integrate that as well.

    Ayah,

    If you are doing this for a school project, I think your instructor will understand that it will take some time. I don't think you will find an easier way to get results than by following Parallax's curriculum, in the order suggested by Chris Savage above. Essetially. all you have to do is buy the kit, open the box, and follow the instructions. If you haven't bought anything yet, download and look at the books to see what's involved. And if you aren't old enough to easily follow the suggestions given, ask a parent or teacher for help with the project.

    Ayah;

    I am not trying to be rude in this post, but am being blunt in hopes of helping you understand.

    If you look at the page and documentation for the gripper kit carefully, you will see that wheels are not included. The Gripper kit is shown in the pictures attached to a BOE-BOT for illustration purposes only. The page states that the Gripper is meant as an accessory for the BOE-BOT, which is sold separately.

    Once again, as has been repeatedly stated, you will need the following:

    BOE-BOT kit: This is the basic robot, including wheels. This included the microprocessor and breadboard (STAMP chip and BOE [noparse][[/noparse]Board of Education] development board. It also included all the parts to make the robot function, as well as instructions and sample code for programming.

    Gripper Kit: This is ONLY the gripper, and meant to be an "add-on" for the BOE-BOT. While it could be purchased for other uses, the mouting brackets, etc. are specifically designed to attache to the BOE-BOT. The only parts included are those for teh actual gripper itself. No wheels, no microprocessor, no nothing except the parts for the actual gripper, and brackets to attache to the BOE-BOT.

    Remote Control: There are a number of possible options, including Blue Tooth, IR, etc. There are specific products mentioned in other posts.

    You can wish things were different all you want. You can ignore the advice and information that you've been given all you want. The net result is that you will still need all three of the above to do what you have asked how to do. For some reason, it seems that you don't believe what is being said here, and it looks like you're trying to tell people who have worked with these items, including people who work for Parallax, that they don't know what they are saying. I think the posts here, and the information on the Parallax web site are actually pretty clear. You need to take some time and READ the information presented, not just look at the pictures. From your discription of the project you want, you seem like an intelligent person. You just need to slow down, take a good look at ALL the information available on the web site, and take the advice of those who have been around this a while, and try not to challange so much those you ask advice from.

    Perhaps the project has become unafordable or more complex than you thought. The facts are not going to change. You seem to be acting like it's unfair, and that people are lying to you. This is really not the case. You have asked some good questions, and then not wanted to believe the answers. The answers are the answers, and are not going to change.

    Ayah;

    One of the problems with a text only forum, is that we can only guess what the spirit of any post, including mine is meant to be. I didn't mean any offense, just wanted to "jolt" a little that the information here is good.

    On the page you reference, look at the "center panel" of page one (labeled "Fig #1". The drawing, and 'Parts List' clearly show what is (and by omision what is not) included.

    The rest of that manual shows how to "apply" the gripper to the BOE-Bot, as the kit is specifically targeted at users of the BOE-Bot.

    I don't mean to be a jerk, but the information is there, and seems clear to me. Just slow down a little, and read more carefully.

    Ok Ayah, I have found an even easier solution.· All you need to buy is the·gripper kit that you have been wanting, then just close your left eye, stick your tongue out of the right side of your mouth·and then snap your fingers twice (really fast though or it won't work) **poof** it should be up and working!· These guys on here have been·really patient in trying to help you but you seem to be just a tad bit stubborn and not willing to be helped.· Maybe you should start with a less difficult project first and then work your way up.· Sorry for being very blunt, but it seems that would be all that works.

    Holy cow, this is an old thread! Talk about a zombie...

    @ blimp

    It probably would have been better to start a new thread and link to this one if you wanted to, but anyway, I'll answer:

    You won't find it, you write it.

    You'll have to think through your particular setup, and figure out what you want it to do and how to go about it. I like to sit down in a closed environment (in class, on the bus/train, church, etc.) with a piece of colored paper and I scribble my ideas and project design on it. Usually it hangs around for a couple of days before making it into the trash, but the important thing to get here is that you have to make some sort of plan for your project.

    You won't be able to get a complete, working solution, but you will probably be able to get pieces of code that you can integrate into a single solution. My guess is that your gripper is servo powered: so write a routine to open the grip, another to close, and another to hold. Write a routine to receive commands from your wireless. Write a routine to send commands wireless. Write a routine to get user gripper commands or generate your own. Put it all together.
