Good subject, signing off

Iron

Had important task to do, back now to finish class.

Iron

Several projects have used multiple axis

Iron

Viewing class from archive from Thornville Ohio

Iron

@fred45, looking at the slides, the master system was programmed in C+ , so something like Eclipse, Qt Creator, XCode, or Visual Studio could be used.

Iron

@lukeandrew. Thanks for the info. I will look into it.

Iron

@fred45, Urs seems to be gone.  Programming depends on the hardware used.  The EPOS2 used in this example seems to have an EPOS Studio environment used for programming, but I'm only guessing, based off their website.

Iron

@Urs. I see your point. Unless, we have all components previos the webinar lecture and IDE for programming.  What is the standar IDE used for programming?

Iron

So, the PocketDelta robot has 4 controllers - 2 busses with 2 drivers each, but only three motors on the pick and place system?  Could you explain what's going on?

Iron

Great lectures and amazing video. Thank you very much.

@fred45: I think that programming should be done in practice on a life system. I doubt it can be done in a webinar type lecture.

Thanks Dr. Kafader, Bob, Digi-key, and all. Excellent series for an introduccion to Robots. A follow-on course for programming simple robots would be nice.

Iron

Thanks everybody for joining, Urs

Blogger

The update time of the master controller in the Pocket delta robot is 0.5ms for the current control loop.

Blogger

@Urs, there should be a less expensive book with the older editions, which cover most of the same information.  A lot of the book is about coordinate transformations.

Iron

Pathplanning: Essentially it is a question of how the mechanics looks like. Each application is different and path planning takes place in the master system.

Blogger

Question from gamatec@email.com

Which is the update time to the Master Motion Commander ?

 
Blogger

@lukeandrew: Thanks for the book hint

Blogger

previous and current exposure to controls is in the aerospace domain... autopilots etc., where multi-axis coordination and control (pitch, roll, yaw and power settings etc.) is required. Some of the concepts should be able to be translated to robotic applications.

Iron

@URS, this book from John Craig is fairly well written, simple and discusses multiple axes trajectory planning: http://www.amazon.com/Introduction-Robotics-Mechanics-Control-Edition/dp/0201543613

 

Iron

?? We've discussed Path Planning. What can we do when multiple arms operate in each other's space? How can we avoid collisions if the path of each arm has to dynamically respond to requests from outside the "Planned" path. How do the arms say "excuse me" and go around each other?  Does each arm update its forbidden-to-others space in a table -- and the other arm has to stay out of that space.  I can see this topic as a whole course for Design News and Digi-Key.

Thanks urs, but this multinational controller may have actions in controlling a satellite dish in a vehicle to adjust to sat, and to have feedback if signal drops off.
Iron

Now that we know how to select the motors and controls, how about a follow-on course on how to program them?

Iron

I haven't incorporated any of these multifqacet systems in work I have done, but see where particurlarly the feedback system can improve system control and function.

 

Thank you for the lecture and presentation.

Thanks for the series of lectures Dr Kafader. Rob thanks for host duties well executed.

Iron

how to buy the cards

 

Iron

Thanks everyone who made this possible...

Iron

Thank you Urs, execellent lecture useful information too.

Iron

Thank you, it was excellent!

Iron

Well worth the price of admission.  Thanks.

Iron

Thank you Urs, Rob, et al.

Iron

wow that was great. Love robotics. Thank you

Thank you so much!

Iron

Thank you Urs, Rob, and Digi-Key

Some video to this robot ?.

independent axis.  
I'm working from an older book given to me by
an engineer who was retiring.  Written for a manufacture by a consultant...  
sometimes overwhelming.

Iron

We're now on slide 23.

No, looking forward to it.

Question from Urs:

Does anyone have a good easy reading textbook about control algorithms, in particular about multi-axis motion control?

Blogger

We're now on slide 16.

Blogger

We're now on slide 15.

Blogger

indepent axis so far.

Iron

conceptual projects would require a fair amount of axis coordination

Iron

3-phase BLDC, stepper

Iron

Do you have multiple axis in your currently developed applications?

In the near future.

Iron

We're now on slide 14.

Blogger

What different motor types have you worked with?


AC, DC, servo, and stepper

Iron

Question from Urs:

How much synchronization and axis coordination do you need? Rather independent axis or strongly coupled?

Blogger

We're now on slide 13.

Blogger

What is the air-speed velocity of an unladen swallow?

I agree with richnass.

Which is the update time to the Master Motion Commander ?

just single axis so far, maybe two in the future

Iron

Question:

Do you have multiple axis in your currently developed applications?

Blogger

We're now on slide 6.

Blogger

AC, DC, Servo, Stepper.

Iron

just getting started in motion control

Iron

only Stepper, just starting in motion controls...

Iron

AC, DC, servo, moto reductor, step motor

Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, if it doesn't start automatically, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.

Another question - perhaps a bit less obscure than the swallow: 

What different motor types have you worked with?
Blogger

Good question, Rich. What's the difference?

Blogger

Here in NJ, all things big/little, laden/unladen, African/European, are water logged,
so very very little air-speed velocity! :-,)

Iron

Did you mean an African or a European swallow?

Blogger

Hello, from Manizales - Colombia.

Hi everyone! Welcome to class three! I have a question for you all. What is the air-speed velocity of an unladen swallow?
Blogger

hi hi hi from Guadalajara!

-The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. If the audio doesn't start automatically, click on the play button to start it. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. Also, make sure your flash player is updated with the current version. If that doesn't work, your company is likely blocking the live stream. The class will be archived immediately following our live taping and you will be able to listen to it then. You shouldn't experience any problems with the audio when listening on-demand.
