Hi,
To make an AHR-3 move autonomously i have the Bot Board II. In the assembly guide it say i will need a 24awg wire to connect the SSC-32 to The Bot Board. Is this the only that can be used? is theer a reason for this specific wire? where can i get this wire?
I don’t understand what you mean by connecting the bot board with the ssc-32 with a 24AWG wire.
Do you mean power? Do you mean the serial cable?
The SSC-32 is a serially-driven device, so the hook-up between it are the serial ports. You connect the TTL/CMOS-level serial connection between the two. The RX and TX pins comes out near the DB9 connector on the SSC-32 board. On the BBII-side, it’ll depend on what ports you designate as a serial port depending on the chip that you put on there.
For instance, if you have an Atom Pro 28 on the bot board, you get to designate software serial ports on any of the ports, but you also have a hardware serial port on P14 and P15, RX and TX respectively. So to hook up the BBII with Atom Pro 28 to the SSC-32, I connect P15 off of BBII to the RX pin on the SSC-32.
Refer to page 4 or 5 on this guide for hook-up:
Not sure which tutorial you are looking at, but I suspect it’s referring to powering the Bot Board from the SSC-32’s supply. If you could post a link to the tutorial it would be easier to help you. 
Looking at the diagram posted, i see the wires connected to the VL on the SSC-32 board. What is this wire called? I thought this was the 24awg wire.
Bellow is the instructions and the link for the assembly…
Step 3.
The SSC-32 should be configured for 115.2 kbaud and DB9 communication, with the VL=VS1 and VS2=VS1 jumpers installed. Consult the SSC-32 manual if needed. Attach the wiring harness to VS1. Connect 8" of 24awg wire (not included) to VS2; this will provide power for the Bot Board. Make sure that the red wires go to (+) and the black wires go to (-). For now, put some electrical tape on the end of the wire. Using four 4-40 x 3/8" hex socket head screws, attach the 1.0" hex spacers to the board as shown.

Yes the wire used to share power from one board to another is what it’s referring to. 24 gauge, 20 gauge, 18 gauge, it’s not critical.
