TTBN Alpha

Description

TTBN Alpha is a remote presence tracked platform controlled trough a web interface.

I have started on this project a while ago in an attempt to:

- demonstrate the use of embedded platforms in the proper way, using a lightweight custom built Linux distribution based on buildroot
- create the simplest possible tracked platform using mostly printed parts, using off the shelf parts where possible
- keep things on the cheap side
- have fun :)

Update: I'm marking this one as done will probably start a new one some day

Details

It is powered by a Raspberry model B, running a custom built Linux distribution.

The web interface is written in Python using the Tornado framework, and websockets for (almost) realtime control.

Video is captured from the webcam and it is displayed realtime in the web interface in order to allow FPS style control of the tank.

The webinterface is accessed trough wireless, making the control possible form almost any device featuring a modern browser.

The system is powered by 3 x 18560 3.7v Li-Ion cells connected in series.

Your github repo seems to be missing the top cover. And is there a battery cover to print? I can't tell how it goes together either since your tracks are installed in all three pictures. Did you describe the assembly somewhere?

Are you sure? yes | no

True the top cover is missing, it wasn't ready, will add it.

Battery cover nope, none.

Assembly, yeah it was on LetsMakeRobots.com but I'm one of the guys who left the site so it's gone.

Just to warn you, this project wasn't meant to be printed it has it's issues, a better version is lurking in my backlog ... don't know when I get to it though :)

If you are fluent with Blender (blender.org) blend file will be on git.

Are you sure? yes | no

I cant wait to see what your new project will entail buddy. Always been a huge fan of alpha - he's still on the 'to get printed' list :)

Are you sure? yes | no

having a wireless charging station option herem would make this a useful option for security.

Are you sure? yes | no

Thanks! And yes I should do something about the SD card though I had no problems so far.

Are you sure? yes | no

Nice clean track setup you have there! I love the way the raspi sits in it! The only suggestion I have is to add a rear bumper - you don't want to back into things SD card first.

Are you sure? yes | no

One of those little adaptors that allow a micro SD card to fit flush into the Pi model B's sd card slot would be perfect.

Are you sure? yes | no
