Newbie Ques....sorry...lol

Can i program the SSC-32 to recieve commands from a 6-channel r/c trasnmitter??? :confused: lets say i want my biped to punch forwaard with right hand while crouching to balance by moving right joystick forward and left joystick backward…can i programm the SSC-32 to do that with the SSC-32 vision sequencer?

Well, to begin with, you would need a microcontroller to store the positions on.
There’s no EEPROM (the same sort of data storage that’s on a USB Flash drive) on the SSC-32, so it isn’t able to store any servo positions.

As is, the SSC-32 is only able to tell the servos to go to the positions that you tell them to go to from another source (your computer, a microcontroller, etc.).
Basically, the SSC-32 frees up a microcontroller so that it can coordinate sensor data, instead of worrying about sending servo position pulses.

Now, once you get that all squared away, it might be possible to have your RC reciever to speak to the microcontroller.
Your reciever would have to be able to send your joystick position data via RS232 (a.k.a. serial port communication bridge).

You’ll probably find that your standard RC controller doesn’t have enough buttons, though (sure, it has enough to walk forewards, turn, and maybe sit down, but that’s just boring, isn’t it?).

You might want to think about either using a wireless PS2 controller, or an Ad-Hoc (fancy word that means ā€œcomputer to deviceā€) Wireless Module.

I’m currently taking the latter route, as I wish to have partial control of my biped from my laptop.
You and everyone else here are welcome to any code that I produce (although, I’m learning as I go, so it’ll be VERY slow in coming).

If you chose to go the PS2 route, you’ll be pleased to find that there is a lot of sample code on the lynxmotion site to help you out.

If you still want to go with an RC controller, be warned…

:slight_smile:

in that case i would need a mircocontroller, the SSC-32, and an ad-hoc? what would be a good ad-hoc?..i have a laptop too and ur idea sounds pretty cool( an entire keyboard to control a bot! COOL!) but the ps2 controller idea is cool too… :confused: oh yea, would the power pak be a good way to power my biped? with the quick connect battery thing? :open_mouth: oh wait! cant i just use the bot board? will it be decreased performace? harder to prgram?..sry for the barrage of ques…lol
thanks! :smiley:

Ahhh…
Let’s see…

A microcontroller (a.k.a. Basic Stamp, BasicAtom, Atmel, BasicX, PIC, etc.) get’s stuck onto the Bot Board, which is a carrier board for the microcontrollers (although I’m not sure if the Bot Board supports Atmel’s or PIC’s).
The carrier board gives you a bunch of inputs and outputs (those pins that stick up from it).

These are connected to servos and sensors.

You would only need to set up an Ad-Hoc connection (via a wireless module, WiPort, Bluetooth, WiFi, etc.) if you were going the computer —> biped route.

If you do that route, you don’t actually need a microcontroller.

The Ad-Hoc network that you set up could function as a wireless serial cable.
You’d be able to control the biped by streaming position data (with the LynxTerm, Visual Sequencer, RCK, or your own program).

You could use a microcontroller with the Botboard and the SSC-32 and the wireless module, if you wish.
I’m going to be using both because I need the microcontroller and Bot Board to read a bunch of sensor data, and the SSC-32 to worry about the servos.

You could also use just the Botboard and a microcontroller with the wireless module.
With this way, you could store all the positions in the EEPROM of the microcontroller.
Then you could send even simpler commands accross the wireless bridge, and have them translated into servo positions by the microcontroller (this way, your sending less data across the slowest connection, which is the wireless bridge).
But, remember, if you tie up your Bot Board + microcontroller with sending out servo pulses, you probably won’t be able control any auxilary electronics (sensors, and what-have-you).

I’m going to be using a WiPort module (www.wibotics.com), mostly because it’s been recommended so well by some of the guys here.

Apparently, many of the Bluetooth modules are slow, which can be a big factor if you don’t want a delay to make your biped fall on it’s face.
:stuck_out_tongue:

I’d recommend the 6V 1600mAh (BAT-08, I think) for your biped.
That battery should last about 20 mins, so I’d get a 6V 4A power supply for when you’re just programming it (the kind that you stick into an electric outlet; more than 4A is fine as well).
Be sure to use a fuse with your wall supply, though.

In summary:

The easiest way to do computer —> biped is…
Computer —> 802.11b network card (most laptops have internal ones) --> WiPort Module —> SSC-32 --> servos.

And, the easiest way to do PS2 controller --> biped is…
Wireless PS2 controller --> Bot Board + Microcontroller --> servos

Feel free to ask all the ā€œdumbā€ questions that you wish.
After all, I was in your shoes about 5 months ago.
