Rob,

I notice your image tags are not used properly. What I do Is paste the link provided from image shack and then once you pasted that link in the forums, you need to highlight the entire link by left clicking and dragging. Once the entire link is highlighted, click the “Img” button at top under the subject field. You should now see two tags in front of the link and at the end of the link like this:

YourImageShackLink

In your previous post, you have the end tag " at the end of the post which is why it did not show up in the forums.

It’s important the the tag begins with and%20ends%20with with no spaces.

I should have told you this beforehand I guess. :laughing:

Hope this helps. It’s easy once you get the hang of it.

Then you can grab any image and post it in the forums like this:

I’ll tell you how to do this once you get the tags right. :laughing:


Muahahahahaha.
:stuck_out_tongue:

That hexapod leg looks really neat, Chris!
Awesome work!

another fellow roboteer burning the early morning oil I see… Yeah :smiley:

Right, so here’s the finished HBKR-01 chassis plates (finally).

It’s a single model file with two configurations - one for the top plate and one for the bottom. I’ve sent it to Jim to post on the website.

Chris

Hi guys,
I was wondering what Version of Solidworks people are using? I am no SW2006, but I can still use SW2005 if need be. Maybe not much longer but I have one machine with it still on it.

Chris nice looking model can’t wait to build a model with that on.

rob

Keep up the good work Chris! Models looking good!

Doesn’t the 06 support importing and exporting in 05 mode? Just asking, I don’t have either. :wink:

I’m using SW06.
Have created a HBKR-01 chassis assembly at Jim’s request. Encountered a slight problem with the plates - the square holes made it very tedious to
position the screws and standoffs, so I created two new configurations
where the square mounting holes are replaced with round ones.
Have sent the models through to Jim.

Chris
With square holes and slots, what I do is in the sketch add a circle as a construction line and center it where I want a default mounting to be located, then use the sketch to mate the holes.
Nice looking assy, I will be waiting for them to post the parts.
Jim is suppose to get me some stuff to model and I am waiting. If you have things you would like to pass along and Jim does mind I can help out.

Thanks again

hi guys what is the length of the hex standoffs for the model Chris just did? I was going to put the body together and throw in th 2DOF legs

thanks

Rob,
Thanks for the tip. I thought of this originally but because it’s a patterned hole, the construction circles weren’t patterned. I also thought about adding construction axes, but that’s an awful lot of axes to add and would be a nightmare trying to navigate an assy with them all turned on (?)

Also, wanted to try and take advantage of the auto-mate feature - where when you insert a cap screw, it automatically snaps to the hole.

I’ve uploaded the file here so you can download the assy and have a look. Let me know what you think should be done to get it right (would appreciate any tips, you’ve got way more SW exp. than me :smiley: )

For everyone:
Another issue that will need to be addressed soon - what would be the most effective way for people to arrange their files? If we all start sharing our assemblies, ideally, they’d all be built from the same part files and everyone’s files would be in the same relative location. (Solidworks does prompt you for the location of a part if it can’t find it, but makes it easier in the long run if everyone uses the same file structure, particuarly with complex assys)

What I mean is: if I built the HBKR chassis assembly and I created it using the HBKR.part file, a Cap screw file and a hex standoff file but I located the cap screw and hex standoff files in a subfolder called \accessories\ (ideally) everyone else would need to locate their files the same to be able to use the assembly file.

The easy way around this would be for everyone to just have all the part files and assemby files in the one folder, but as more models get added this will get cumbersome.

My initial suggestion is to arrange them in subfolders arranged in the same way Jim has them arranged on the website i.e.
\Brackets
\Chassis & Acc
\Tubing, etc
\Ball links\

I think we need to come up with something reasonably robust, 'cause once we choose something and start making lots of assemblies, changing the file structure later will be a pain the the butt!

Any better ideas/suggestions are most welcome :smiley:

Chris

Oh yeah, Rob, the hex standoffs I used are 1.875"
Would you mind uploading your 3mm bearing and rubber end cap models? I still haven’t found a decent bearing. (you can try uploading the files to savefile.com or rapidsharing.com, it’s free and no registration required, then just post the link it gives you, here)

Cheers,

Chris

Hello all,

I need to step in here and lay down some ground rules.

First off I want to thank everyone who has assisted and who has offered to assist in this large project. Without all of the help it would not be possible. I am very excited to be able to offer the 3D files. It will make many cool things possible.

I need for the created files to exist in one place, our website.

There is a notice on the 3D files page stating:
Note: These CAD files are provided to aid in building virtual models of robotic assemblies only. We are not giving permission to anyone to manufacture these components for commercial sale or personal use.

In addition the files residing on the website fall under the copywrite of the Lynxmotion web content.

Now I know some people are going to make some of these assemblies from the provided information. I can’t do much about that. But I feel the eventual benefits will outweigh these situations.

The final reason is exactly what Chris has mentioned. We need to have one place where all of the parts can reside in a controlled structured way to keep it organized.

Please route all models to Beth [email protected]. I will leave it to Beth and Chris to determine the best file structure.

I invite any comments on this. Thanks for everything!

Chris has a great idea we do need to setup a standard and follow it. The Dir structure is not a big thing if poeple remember that an assembly file on contains links to the models, not the models themself.
If all of the parts get unzipped into one dir Solidworks will find them without asking for your help. It gets screwed up when the dirs come into play. So I would say break it down like the web page.
The next problem is the fasteners. I see that Cris is using Toolbox to create his and he has configurations setup for the lengths. This is quick, but I have gotten away from the configurations and each length has it’s own file. We need to have a standard for this also. I would say that we get the fasteners al modeled that Jim sells and posted to everyone use the same ones.

Chris I looked at your assembly, I had an error due to having a part named the same thing as you. but not a big one. I created a model of the hex standoffs and used the design table like you, what I did was named the configurations the same name as Jim’s parts, and added the discription to the configuration. So it would show up in the Feature tree as a part numer and in a BOM on a drawing if people wanted a quick way to figure out what they need for qty.
The other thing I did was inserteed to standoffs and mated them to your sketch of the sq hole, then used the pattern by feature in the assembly to pattern the standoffs around to the other sq holes. Works great, did the same for the fasteners.

I thnk that’s alot for one message.

rob

Chris I sent those to Jim last week. Not sure if they got to Beth or not. I tried both of those web sites and I could not upload a file. My computer guys told me it could be our firewall and the way they do things. not sure. I was going to send you my assy of the Hex so you could look at how I did the assy and the fasteners.
I figure it out some how.

I totally agree with Jim’s comments. (I’ll quit uploading models and let Beth handle it :blush: )

Some best practices need to be worked out. Rob, I think you’re experience here is going to be invaluable. So, things that may need to be considered:

  • directory structure
  • file naming convention
  • who’s model should be posted in the case of two people modelling the same thing? (how to figure out who’s is better?)
  • use of configurations vs. individual files

Jim, maybe hold off on posting my HBKR-01 assy, sounds like Rob has his setup better…

Chris

Um… whistling :unamused: sure, I sent them to Beth… Quickly forwarding emails to Beth…

Would it be too much trouble to have a version column (and maybe date posted) on the page where the models are posted? When a model is first posted, it could be designated as a “Beta” version, then people can download it at their own risk, play around with it, make suggestions etc. and the model can be improved upon. Then say, if there are no more suggestions after a certain period of time, the model gets upgraded to version “1.00”.

That way, if improvements are made or designs change, people are able to tell what version they’re working from.

Anyway, just an idea…

Chris

chris great idea, in fact we should great a custon property that has a revision in the model.
