hi all, i have start a biped walker, but i have noticed some servo are heating, on the shème the q2 and the q8 are heating, and the q6 and the q12 not supporting the weight when the other feet is not on the roof. however, i use mg995, 15kg/cm @ 6v servos. it is possible my battery isn't charged correctly? how to be sure?

main characteristics :
weight 1.5kg
height (when stand up) from roof to q2/q8 : 28 cm
distance from q2 to q8 : 12 cm
all servo mg 995
servo controller from parralax http://www.parallax.com/Store/Accessories/MotorServoControllers/tabid/160/ProductID/376/List/1/Default.aspx?SortField=ProductName,ProductName

thanks from Belgium my friends.

There's your problem :/

MG995 are advertised as 15kg.cm, but they are nowhere near as powerful and precise as you might want... Plus mechanically, they are quite fragile, compared to their strength.

Like many others, I wasted money on these servos that look good on paper, and they are really not what you want to use for a robotics project... sorry :/
