Servo/Battery Efficiency

Hi guys! :mrgreen:
So I was browsing through various bipedal robot models (I’d been watching some Robo-One footage again :wink: ) and there was something I had to ask about servos and batteries for these kind of models.

Looking at the Kondo KHR 3HV for example, the Robotshop website states that it uses a 10.8V-800mAh battery - now am I missing something here or is that rating way too low for a robot that’s doing backflips and cartwheels or are Kondo using some super efficient servos? :confused:

Thanks,
A.K

The Kondo battery is very small and lightweight (for a walking robot, the servos take up the most of the weight, followed by the battery). For normal walking, the servos would not consume much current, but when doing a backflip or other motion where the current is high, it simply means the battery pack will not last long. A LiPo battery pack can often discharge at ~20C, so it’s more than capable of providing the needed current in short bursts.

Ah right I see - thanks for the clarification. :mrgreen:
