From RoboBrothers.com (Livermore, CA) came the first sub US$400 humanoid robot kit to appear late 2007

can you use the standard charger with this battery pack?

the charger that comes with the kit is only rated at 1000mah I think.

The 1000mah pack, I charged with the included charger. I would think it will charge the larger pack, but I have not tried that yet.

I have also used a hobby type charger on all my packs. That seems to extend the run-time on any battery you use. However when you unplug the battery you must reload the fine tuning as philo seems to 'forget' that stuff when the battery is disconnected.

I must be doing something wrong. Once he is all tuned up do you save to the file on your computer, then reload those settings onto Philo himself? if that is true then, :oops: ,my bad.

Curiousity killed the cat, so I grabbed my trusty micrometer and took some measurements.......

Stock Philo pack cells are 1.19 in. long in the wrapper, the pack itself is 1.12 in. wide(two cells across).

The 6.0v 5cell 2/3A reciever pack cells are 1.10 in long in the wrapper.

Now remember I have two seperate packs from two different suppliers (one 1000mah and one 1600mah) that are just about the same size. Could be they're not 2/3A cells, but they are certainly easy to get.

Can I use Robophilo while charging it or do I need to charge first and then use it? I want to use it for some experiments, which takes long time. What can I do?

you can use the robot while charging. This is preferred to do motion programming. If the battery is completely drain, you'll need to charge the battery for some minutes first. Certain pose may draw 3A current for the 20 servos, the battery will supply current in addition to the 1.5A from the power supply. This approach can provide programming for a few hours.

can I get a 6V external charger, which I can directly connect to the robot and use it in the place of the battery? I don't want to use the battery any more. I just want to charge it using the external power supply. can I do that?

You can buy an external power supply for 6V 3A with the correct plug and polarity. inside pin is positive.
