Project Phoenix, a hexapod robot

Hi LikWidChz,

I think we are pretty much the same on this part. I also want to know exactly how it works and rather build a whole new program then just load another program. That’s why I didn’t adapt the powerpod application but started one from scratch. :wink:

In the Netherlands we say â€

Wha whaa! Vista is fantastic when you have a box that runs it… sure its a little bloated but it’s an OS that’s a bit ahead of the game… I really don’t have anything bad to say about it :slight_smile:

anyway, heres a screenshot of my settings and program im trying to program which takes roughly 10-15 minutes to write

The thing’s I have fiddled with is the transmit buffers/receive buffers
The Bit’s per second rate 128k, 115k, 57.6k – for the most part it all is slow as sap on a cold day in the antarctic!

Note: I answered on the other thread…

OK, I’ve set the AH3-R aside for the time being. I’ll get back to it after the new year. I started assembling my Phoenix, so I could have something to play with while on Christmas vacation. As I unpack things, then first thing I notice is how small the body is, remember I’m used to the AH3-R. As I’m assembling, I’m watching any available space for a battery disappear. I have a coxa’s and SSC-32 installed; and will be installing a BBII on top. Where do you put the battery (5-cell sub’C’ NiMh)? Oh yea, and I’ll be adding the PS2 receiver stuff too.

Just can see the obvious!

Cor2 yeah Ill show you how i tweaked mine, I noticed the same thing atleast to get some ideas, It would be nice if they corrected this hickup in possibly a new run of the phoenix bodies

OK so the first image shows where I moved the 4 supports that hold together the Phoenix body I moved them out roughly 1/8th of an inch and this does not conflict with any other components inside there is a bit of room to spare if you have wider batteries

The next is looking in between the plates and showing how close I have the SSC32 to the top of the upper deck portion, these are 1/2 inch spacers

The next image shows my Battery pack I soldered together 4700Mah batteries seem to be the biggest umph you can get in sub-c style cell’s and these were roughly 5-6 bucks a cell… NOT a bad deal at all.

Hope that gives you some idea’s I’m waiting for our snow to clear here so I can head down to frys and pick up some 2-3 inch wide clear heat shrink and wrap my battery along with a connector.

nice work! BIG PICTURES! :open_mouth:

you could turn the SSC over so that the wires are not pointing out the top :bulb:

Thanks!

I could do that except that battery pack is going to slide inside it and the servo wires would interfere with the pack so probably not going to work :\

If that ssc32 had horizontal connectors rather then them coming straight off the top that might work, except it’s almost like you need to cut the servo wires shorter cause some of them have quite a bit of extra stuff on em…

I think if the phoenix robot were scaled up a bit it might be better too you can put more of a payload on it maybe 1-2 inches longer and wider wouldnt make it look that awkward looking “I THINK”…

anyway yeah ill post more crap about how its coming along here within the next couple days or so and make the photos a bit smaller :\

eerh der! me not thinking! sorry!

well i look forward to see the future developments.

i though this last year when i was faced with the same prob!

you could always mount the SSC on the top of the body (facedown)
and have four of the smaller hex standoffs holding it in, and then
fabricate a 3x2 plate to protect the SSC! also if you were to drill
holes in the middle you could always attach a servo to it
(upsidedown) using the servo horn!

That’s a fantastic idea

Good good, I’ll do that,

what did you mean by this

??? I’m missing something?

–Aaron

ill try and paint you the picture…

ok you have reversed the SSC (facedown) with Hex standoffs and NEW plate over the top of the SSC!

follow?

ok good now, take the plate off again and find the centre of the plate. use a pen to mark the centre!
Get a servo horn, and place it in the middle of the plate and using something small mark out where the horn holes are on the plate!..
(can also use SES bracket)

: : .. ..o.. .. : :
Drill out these holes!
[size=75](sorry for silly diagram!)

Ok now you have the Plate with holes init, you need to get a servo and screw it onto the plate.

now turn the plate over so that the bottom of the servo is facing up?!
screw down the plate again over the SSC again!

Now you have a Head!!!

if you cant follow this i will try and dig out one i made a while back.[/size]

Yeah reversing the ssc32 so its upside down and the wires are “more hidden” that makes sense…

I’m not following why i would need to drill out these servo horns?

I wasn’t planning on doing anything with them, could you have misunderstood me?

YEAH I understand your silly diagram heh, but … how about you post some pictures …

–Aaron

sory to confuse you. your not drilling out the servo horn, but use the servo horn to mark out holes on the plate!

iv used pvc pannel for this but i guess you would use aluminium!

Well thanks for the photo… I’m still a bit lost why i need this? not sure why I need the ssc32 on a plate with a servo attached to it???

–Aaron

moving the SSC onto the top of your body rather than inside and then
reversing the SSC so the wires point inwards will allow the wires to be tucked away…

AS an idea you could a servo to the top of your bot (maybe for a pan&tilt).

a way of doing this could be too have another plate over the BACK of the SSC and have a servo attached to it! Giving you the panning head! just an idea!

thought you got this?! :confused:

:confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused:

OH no no, I thought your idea about mounting the ssc32 upside down was fantastic… I just wasnt connecting your idea about why i would want a servo horn on top of the ssc32 controller thing…

!! makes sense now…

Yeah I think as for the top of the ssc32 and the top side of the phoenix id like to get some sort of plastic dome or something to that nature… not really sure… whatever really just as long as it looks clean…

I still have to mount that botboard, put my 5 subC 4700mah batteries underneath it all, and mount a 4 channel futaba receiver in it… oh yeah…

AND WRITE THE SILLY CODE!..

well there are may variations of the code about at the moment thanks to Xan & Zenta so i wouldnt worry too much about having to write a code.

good luck with the project tho! 8)

See that’s the thing, I respect them for writing that complicated code, but me starting from that point would be silly, I wouldn’t really know what I was doing rather then just modifying some variables and all that crap, I want to understand it and the only way for me to do that is write my own… I’m not quite sure what my goals are but at least get it to move forward with rc control.

–Aaron

Oh and here is the battery pack almost done

and then after some blow toarchness

Hey guys, here’s an update to the project

First image here is the charger I bought that charges nearly every battery, It’s very small because it doesn’t plug into the wall :\ I have a computer power supply that I’m dismantling and putting in an acrylic case with a fan, so I can have some stable voltages for various other projects
“+3.3/+5/-5/+12/-12/Gnd/” Anyway that being said
http://img241.imageshack.us/img241/822/Charger.jpg

Here is the cable I made to charge the battery in the Phoenix… The shorter wire that comes off it is for a normal 7.2volt pack “I don’t have any… why I put this on it is beyond me”

http://img241.imageshack.us/img241/1308/ChargeCable.jpg

Here is the 6volt cell I put together with 3 ends on it … 3 ends… why this many… well… one for the bot board one for the ssc32 and one for the charger so i don’t have to unplug anything!

http://img241.imageshack.us/img241/329/Battery3.jpg

and then the phoenix

http://img241.imageshack.us/img241/2356/Spidy1.jpg
I really like the aluminum spacers that really helps manage the boards good and keep the wires where they should be,

I still haven’t added my Futaba 8 channel receiver that needs to be fed into the bot board2 somehow and needs to get powered and I need to give the phoenix a cute looking tail that sticks up in the air, I have 4 other S3004 servos that need to be used for something… anyone have any ideas?

http://img241.imageshack.us/img241/511/Spidy3.jpg
And here it is puking out some wires!

Well thats it for now!

anyone anyone have any fantabular ideas?

–Aaron

looks really neat! i really like the battery idea, u’ll have to let u know how you get on with it!

i understand what you are saying about writing your own code. wish i had the know how to do that. i do understand some of the code, well i know what most of the lines mean and what they do, and other things but i could never fully write a code from scratch. …but i am learning!

just looking at different hardware ideas at the moment and concentrating on some fabrication ideas i have.
