trying to get a robotic Arm Clamp Claw to work.
I have look at the tutorials and I still cannot make it work .
I have been working late and not have the opportunity to get back
to you all. I will appreciate any help that I could get.
I will post a few pictures.
Thanks to all
Upgrade to ARC Pro
Your robot can be more than a simple automated machine with the power of ARC Pro!
Based on your post activity, we found some content that may be interesting to you. Explore these other tutorials and community conversations.
Lets start with this...
1) How much knowledge do you have in robotics? In using servos?
2) Do you know how to make a servo move with the ezb?
If not much and no are your answers, then we have some work to do...
If yes, are you aware of the Auto Position control in ARC?
Also, buy some rechargeable lipos or niMh batteries instead of using alkaline... AAs won't work very well with servos...
can you make a printscreen what you have sofar
Hi there. To help you on your way, there is a lesson on using servos that might help you getting started.
I have also supplied a link here that gives you some more details about using the Auto Possition control which may help you out with the arm.
After that a good place to start with your arm is to open up an Auto Position Control. Here's a screen shot of my Robotic arm.
Add a picture of your arm and place your servos around the arm with the "Add Servo" button, in the lower right hand corner.
In the upper right corner of the window, you will see "New Frame" click on that and name a "position" you want the arm to move to. I started by creating a frame called "Rest".
I'm going to assume you have all of the servos connected to your EZB. So now power up and connect to your EZB.
Click on "Port Edit Mode" in the upper left hand corner, select servo and a window will open, click on the port you have that servo connected to and save that. That window will close. Now, if you click on the "Realtime Update" button, that servo is going to move to 90 degrees, you can now move the servo to the position you want it to be in when in the "Rest" position.
Repeat this for all of your servos, so that they are all in the position you want for a "Rest" position.
From here, to make a new "position", I always start with the arm in the "rest" position, select a "New Frame", name it and then move the arm into that position.
Once you have a few frames then you can move to making an "Action" or use these to create command controls.
I hope this helps you to get going, let us know how you make out.
I've got a bit of time, so to help get you started, here's the first steps to test the servos and get them moving.
Make sure you battery is fully charged and the right voltage for the servos your using. (As Richard mentioned, LiPo'ss or niMh batteries are the best to use).
Connect a servo to any digital port on your EZ-B ensuring it's connected the right way around.
Load a new ARC project.
Connect the EZ-B to the project using the connection control.
Click on the "Project" tab on the top of the menu ribbon of ARC.
Then click "Add" on the control button on the ribbon menu.
Click on the blue "Servo" tab.
Click on "Vertical Servo" to add the new control.
So now we will set up the servo with these simple steps.
Click on the little gear icon on the "vertical servo" control.
Click on "Port" and select which digital port your servo is connected to. Then click on "Close".
Now, on the Min and Max tabs, the numbers should read "90" which is the default setting. Left click and hold the mouse button down on "90" on the "Min" setting, and move your mouse down and up. At this point the servo should physically move. Change the min number to 50 and release the mouse button. (The minimum setting is 1, and maximum is 180).
Now do the same on the Max setting and chance the 90 to 150.
Press save, and the servo settings are now saved.
Now You can click and drag your mouse on the number, and the servo will move.
So give that a go over the weekend, and check out the tutorials also, and once your happy with that, then you can have a play around with the Auto Possition control. Good luck and post back if you need any more help.
