;D Hello!
Wow! never thought of using a battery housing for a robot!
Very Creative! You could make a cross between Dr. Whos' sonic screwdriver and his robotic companion K - 9;)
On a recent movie, a bot was inflatable from a smaller device. Option?  :-\
Good Luck!!   :) :D ;D

Haha, thanks! For now I'll just work with this thing to completion.

Robot Videos / Robot created from old RadioShack flashlight...
« Last post by Botyard on May 28, 2015, 03:38:05 PM »
I have been creating a robot from scratch using an old RadioShack flashlight I found at the junkyard.

It's been fun so I decided to create a YouTube video series of the process.

So far there are only 3 parts but I plan to keep going until the Robot is 100% complete. Maybe I could get suggestions on how I can improve or do things better with the robot. I'm pretty new to this stuff so all comments and suggestions are very welcome!

Here's part 1 of the series, https://youtu.be/JzeoNbCKu6I
Here's part 2, https://youtu.be/Vc9OcViOAYc
And part 3, https://youtu.be/eCJVRt-wn2o

The first two are probably a little too long. I've decided to keep them down to less than 5 minutes now, so on part 3 you'll see I've shortened it and made it more manageable to watch.

Thank you for watching and I seriously hope to hear from you!

Software / Re: Creating workspace for WebbotLib Studio in Ubuntu Mate 14.10

Works for me on xubuntu 15.04, hmm... if you think this is a bug you should contact Mr Webbot. The only other thing i can think of would be a corrupted Studio file (ie: redownload and try again).

You can also try copying your workspace folder from your Win8.1 machine to your MATE machine via USB, network, etc.

I tried going into the permissions of all of the .jar files in the same folder as WebbotStudio.jar and giving them all permission to be executed as a program, but to no avail. I also tried running the program with OpenJDK 7 and standard Java 7 from Oracle, neither made any difference. I didn't have high hopes, though, because I was able to run WebbotStudio just fine on Windows with Java 8.

;D Hello, and welcome to the forum!  ;D
I may have the answer to your question in my post in the miscellaneous
section, titled, Analyzing the Axon: Coding, Construction, and Contraptions.
Only for the windows portion, not for Linux distros.(yet  ;) ) It is taking me awhile just to
get a hex file made to program the Axon.  :P  There are a lot of computer configurations and files
that need attention, in order to program the Axon. I have started the post, in hopes that it will
help everybody starting on the Axon(especially me), and any questions that could be asked,
will be responded to in my post. Never give up, Never surrender!  8)

Thanks for the response mklrobo! I checked out your post, but I didn't see anything that pertained to my specific problem.

You have selected the wrong directory, it should be "/home/user" where 'user' is your Ubuntu login username, ie: the user you are logged into. (My folder would be, say, "/home/voyager2", yours might be "/home/hopding", etc)
The "/home" folder might not be writable on your *buntu but your actual home folder (above) should be.

Thanks, voyager2. I should have mentioned that I have tried a number of different file paths in addition to "/home". I have tried "/home/andrew" (my actual home folder), "/home/andrew/webbot", "/home/andrew/genericNewFolder", and I even tried straight up "/", to name but a few. None of the paths seem to affect it, though.

Electronics / Re: How to connect everything?

 :) Hello!
If this is related to another post, and desa-vu happens, it will be ok.  ;D
From your description, where you are, and where you want to be, and what
you have, I would suggest the following;
Go to Parallax.com and check out their basic stamps. They have tech support and
an electronics (basic) description for their projects. Good investment, and lots of
instant learning.(all good, I hope!  ;) )
In so far as your parts, I would get a ready made robot kit, then use your parts to
integrate into the projects, where permissible. Any chips that are on the boards,
remove with caution; excessive heat can destroy the chips.
With all your stuff, your could make a MEGA - robot!   ;) Good luck!!  :) :D ;D

Mechanics and Construction / Re: Low Friction Potentiometers
« Last post by mklrobo on May 27, 2015, 04:30:56 PM »
 ;D Hello!
I have not had any time to use micro servos, but have read some material on them.
I have use industrial motors and servos, but still, modular repair was what was done on them.
I would imagine, to acquire positional feedback without pots would guide you into  infrared
detection, or some light triggered metering device.
In the book, "Programming the propeller with Spin", page 204 - 205, indicates counting the
pulses
that was given to the servo. The pulses equate to time, in which, pulses can be converted to
degrees of change.(scales of movement) They compared a pot reading from an analog to digital
convertor would be 0 to 4,095; whereas a signal pulse goes from 750 to 2,250 microseconds.
The cheaper cost of the control is replaced with the labor/memory consumed to program this
control program. But, at least, another option. Good Luck!!!!   :) :D ;D
