Misc / Re: Raspberry Pi info, to use with Axon
« Last post by mklrobo on April 09, 2016, 08:44:08 PM »
 ;D Hello!   ;D
I have found a great source of information about the Atmel processors, themselves. The path is;
http://microcontrollershop.com/default.php?cPath=110_151
They also have tutorial software to the processor itself. This should relieve some frustration about
programming, and the internal expectations of the MCU.

Mechanics and Construction / Re: Finding replacement screws for a RAD v1.0 robot
« Last post by bdeuell on April 08, 2016, 09:44:47 AM »
these look like standard thread forming screws for plastics with a pan head and philips drive. it is hard to tell the exact size from your picture without accurate pitch and diameter measurements. if i had to guess i say it might be a #6-16 in .375" and .500" lengths (it could also be a metric screw its hard to tell without accurate measurements)

honestly if you only need a couple i would just take apart some junk electronics, these type of screws are very common for plastic enclosures. just make sure the thread pitch, diameter, and length match up.

note these have a flat tip where wood screws are pointed, you probably wont find these at a hardware store so you would likely need to order a whole box of them.

 ;D Hello!
The screws look like wood screws, but the threading spacing is off. I recommend going online to:
https://www.fastenal.com/ -- They are an outlet that has about every construction item you could dream of.
If you find that another type screw would work, and is more available, it might be a good idea to
replace the insert in the device, to accommodate the new screw. Good Luck!!!

Misc / Raspberry Pi info, to use with Axon
« Last post by mklrobo on April 07, 2016, 10:35:12 AM »
 ;D Hello!
      I have found a neat website that was helpful for solving problems with the Raspberry Pi;
http://elinux.org/RPi_Tutorials
I am still working on my Axon, and with my Pi 2, to try to get them to work together.
The AvrFreaks Atmel Community website has a lot of help dedicated to the Axon type
processor, along with the other classes of Atmel processors. For those who are arduously working
trying to solve Pi/Axon problems, I hope this helps.   ;) :) :D ;D

Thanks, hopefully these photos should show enough detail, The diameter including thread seems to be 3mm.

i am not familiar with that robot but if you can post some pictures I may be able to help determine if they are standard hardware.

Robot Videos / Matrix - Scratch Built Hexapod running my own code.
« Last post by mturneruk on April 06, 2016, 02:03:18 PM »
Hey fellow roboteers.

This is my first post here. Really glad to of found a robot forum to share ideas and stuff.
Hoping for a bit of advice on motors, for my next project.

In the mean time. Here is my first robot called Matrix (After the rotational matrices used in the maths).


And here is my Video Build Log.

Any feedback or suggestions for improvement much appreciated.

Cheers
Martin

Mechanics and Construction / Finding replacement screws for a RAD v1.0 robot
« Last post by caramellcube on April 06, 2016, 12:15:04 PM »
Hi all,
hopefully this is the right place for this question, if not then apologies in advance. I'm trying to rebuild a RAD v1.0 robot, but somehow managed to lose a number of the original screws. None of the local suppliers sell anything like them and I'm not sure what to even search for online. Does anyone know if the screws used in the RAD series are a standard type, or something custom made for that robot? I have a few photos of the screws in question if that would help.

Oh, while I'm here, would this part of the forum be the best place to start a build log?

Misc / How to make a control car via bluetooth with a raspberry pi2
« Last post by Willxpr on April 05, 2016, 05:09:31 PM »
I'm starting to make a car controlled through an android app via bluetooth using a raspberry pi 2, but I can't make the link bluetooth works and also how to program the raspberry to work only controlled through the app. I'm using RASPBIAN OS and PYTHON TO WORK.

How do I fix this or what do I need to do to make this work?

thanks for the reply, when i search repetitouch it just comes up with an app, i'm not after an app rather the robot/motor device with the repeating action. could you get a link to the ebay ones you've seen?

thank you
