I have a CHR-3 Hexapod with a SSC-32 and Bot Board II with an Atom Pro. I built the hexapod and programmed it using Powerpod and Basic Studio correctly. However the hexapod works when I use the Lynx PS2 with the hexapod on a stand but do not work when the hexapod is put on the floor. It loses power after pressing a single button on the PS2. It is as if the body is too heavy for the servos to work. I am using a 6V mains power supply and a new 9V battery so the power is at maximum.
What are the power ratings (in amps) for the 6v psu?
What servos do you use?
Did you remove the VL-VS jumper?

The current from the 6V power supply is 2.3A. The servos are Hitec HS-485HB and finally I did remove the VS=VL jumper.
does it hold power for a period of time, in till a button is pushed. sounds like the BotBoard is resetting!
or…
can you supply us with a photo of your wiring? im suspicious of the wires connectors you may have used.
are you using the correct wire? 18awg!
you will find that the 24+awg wires will not give the correct current flow.
not sure is this is the problem as we would need a photo to correct this.
Yep. It holds until a button is pressed. I used the 18swg wires and connected as in the tutorials. My digital camera does not work anymore so cannot send pictures yet. So I think you are right to suggest the Botboard is resetting. What can I do?

You’ll probably need a more powerful psu or use a battery. Psu of 2,3 amps is to weak. At some point the current draw is larger than that and the voltage will drop causing the BAP to reset.
too big voltage drop when servos are under load. choose another power for servos, something around 5-6v 15Amps
also servos might be too weak for bot but power supply is 100% too weak
Thanks very much. You both were absolutely right. It was the power supply. It does not lose power when I connect a battery suply with more current. I appreciate your help. Take care
great you have solved the problem. id say 8/10 posts asking about problems are power related. i sometimes forget this and end up looking right through my code to see what i did wrong, but it always resumes to be the power.
It’s easy to assume that something plugged into the power socket will give you what you want
I just started my project, and ordered some dead-cheap power supplies off Ebay, thinking that’s that. 6 and 12V, both 1 amp.
So now, when I stretch the arm out, the power dips too low and the whole thing resets. Serves me right for getting cheap stuff, heh heh.
