Im using the Arduino IDE off OSX Lion, my microcontroller is a Arduino Mega2560.
Kit is essentially the AH3-R with a tiny body, servos however are HS485HB.
I've got my construction, programming, and circuitry down, guys!
But unfortunately...
What I need is a power supply.
So far, I made do with sealed lead acid things.
I have a feeling that might not be practical... plus they might squash my hexapod like a bug XD

So, I need a light, rechargeable power source. Preferably at 9.6v @ 3.6A

I know I could just use 6.0v powerpacks, but I like regulators(in this case, L7806ABV). I know its a teensy bit inefficient... Anyway, Would like to power through those and if thats just stupid, tell me please XD

I would really appreciate input as to what other people have done/think I should do.

I just dont wanna buy a 20 buck power supply only to find its alllll wrong XD

Thanks guys!

look at hobbyking.com for a charger and battery!
You will need a 4s battery pack and then a lipo voltage regulator... and heat shrink you don't want those shorting!

Using a power supply and cheap 1 amp linear regulators is well, lets just call it silly. ;) When servos are commanded to move they need a fair amount of current in a hurry. The absolute easiest way to do this is with NiMH batteries. The 6vdc NiMH batteries can be used to power the servos directly without the need for a high current regulator. We sell the batteries and chargers for this.

Lipo is awesome, but require a high current regulator which adds cost and complexity. The NiMH solution is much easier. I wouldn't recommend a 4s Lipo anyway. A 2s will be much easier on the regulator if you go that direction.

Hah every time I see your chat icon thing I crack up! Beer robot.

Either way there are a ton of options do do what you want, but what everyone wants is the most capacity with the lightest weight.

There are a number of criteria to consider when choosing a power solution. Ease of use, cost, and safety are also important. Depends on the builder. That's a fully functional biped beer robot... :)

... Videos!

I think you should send one of these to xan and zenta to work there magic, I'm sure they will have it walking like a human in an hour !@#... either that or a phoenix :)

/sigh James did the video when he was 16 years old.

Clarification please: Is the robot fully functional only when the bottle is full and the robot is empty, or also when the robot is full and the bottle is empty, or is there a sliding scale of functionality based on the relative fullness of each, and is there a predictable, graphable time lag between fluid transfer and functionality alteration? I'm so confused. :? :? Does the relative fullness condition of the operator impact the equation? :roll:

BTW: do you sell this kit by the case? :)

I think there only is a functional relation between the bottle and the boss being empty/full ;)

Nice Vid Jim!

Xan I think if you had that SES robot you would make magical things happen with it such as your skill with the Phoenix!

Now if you could just scale-up the 'bot, and have it handle kegs!

Transporting bottles on a cart avoids having to have an arm to grasp the bottles.

Might be an interesting way to retrieve things. Although the proportions might throw everything off.

Since we have completely derailed XenoPhobe's thread I may as well add, the cart was not attached to the robot in any way. The hands were actually gripping the cart. It took him literally two hours to make the video using the original Sequencer program.

Oh yeah, I see that now.

Sorry about the thread!
