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
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. lynxmotion.com/p-426-60-volt … -pack.aspx lynxmotion.com/images/Produc … usc-02.jpg
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.
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…
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
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?
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.
Haha, I am thoroughly enjoying having my thread derailed Thanks for the advice on the NiMH batteries, I think my main problem has been highly underestimating the current draw of this damn thing. Im thinking Lipo, anyone have any suggestions for high current regulators?
What size battery are you guy’s inputting to the Castle Creations bec? I’m using a 7.4 20c 5000 Mha Lipo directly to the ABBII bot board and parallel the bec to the SSC32 programmed at 5 volts on 19 servo’s plus 2 X-bee’s plus a stepped up to 12 volt inverter for my wireless camera plus wireless Ps2 controller and a cooling fan ( really not needed but looks cool )
6 servo’s are Hitec Hs-5645MG and 13 servo’s are Hextronik HX12K MG’s
This all runs simultaneously with no issues for a long time ( I haven’t timed it yet ) but over 45 mins that I’m aware of.
The Castle bec can deliver 7 amps continuos and 10 amp burst, I noticed the Dimension engineering can only deliver 3 amps.
