Extreme Hexapod 3-R - Microcontroller problem

Hi guys,
I have been awarded with one of these [1] oldish hexapods. I have successfully assembled it by following the orders from here [2] and builded its physical body.

However, I cannot load the firmware that is mentioned there. I don’t know why but the reason seems to be the microcontroller that is shipped with the hexapod.

Assembly guide mentions about a microcontroller called “SSC-32” but my microcontroller is Motorola and it only has a stamp as “dsp56f807py80”.

I would like to ask where can I find the assembly guide for this microcontroller that I will use to run my hexapod? I really don’t have any idea. It is totaly different.

Many thanks.

Hum,

“awarded”? A gift of an un-assembled kit? You should have an SSC-32 BOARD in your kit. And a mini BB (predecessor to BB2).

Maybe someone mixed up the parts in the kit? I can’t recall any motorola parts in a LM kit.

OK, the pix of the board just came up. Doesn’t look like an LM board! What numbers/letters are on the board its self?

Maybe make a list of the electronics in your kit, and we’ll be able to help you sort it out.

Hi Alan,
Thanks for the reply.

The board does not have any number/letter on it except for this Motorola dsp thing. I know, this is quite strange… But I was the first one to remove the kit’s package.

I will make a list of components on the board today and sen you.

Btw, there are two options;

  1. LM has send this kit with a wrong board.
  2. People who ordered this product has ordered a different board other than the actual board needed (SSC 32 etc.)

For both, I will contact with LM and the person who gave me this kit.

Hi,

I just had to do a little search around this board. It is a ServoPod board with a pretty powerful 40 MIPS processor. And it was delivered by Lynxmotion: lynxmotion.com/Product.aspx?productID=225&CategoryID=7 (so no mixup Alan :wink: ). You’ll also find a link to a user manual and schematics there. Hopefully you’ll get an answer from Jim on monday about this board and if there are any program available. The easiest way would changing the board into a SSC32 and BB2 (like Alan said).

Thank u very much zenta,
Then, I am waiting for an answer from Jim on monday.
It will be very appreciated to exchange my board with a couple of SSC32 and BB2 things.

Let’s see.

Servo Pod board!

That is a while back. Glad you could recognize it.

Yes that is a ServoPod board. For a short time we packaged them with the hexapod kits. The programmers at New Micros did a good job of making the hexapod walk using that board. They had the robot walking in any direction (translation) but they never did solve the problem of rotation. So you can follow the tutorials on the website, but the bot will not rotate, only translate.

We no longer carry the ServoPod, and have not included it in kits in years. So currently the only method of support from us will require the SSC-32, Bot Board, Atom Pro, etc. Sorry…

Hi
I have found an SSC 32 board last night. Thank you all for helping.

Cheers.

Hi guys, here another problem that I have.

I have wired the hexapod with the given manual. Then connected my DC Power Supply with 7.2 Volt and aproximately 1,6 Ampere limit.
However, servos were working so slow. After they have organized their position, it was not possible for the hexapod to stand straight on its legs.

I wonder the reason of this behavior. If it will require more than 1,6 Ampere, should we feed the board? What solution are you suggesting?

Thank u.

You need around 8 amps to make the hexapod walk. :unamused:
