anyone can help in selecting SPG30E dc motor?
which must consider high torque or high rpm? (in balancing robot context)
confused to make decision.

High speed and moderate torque is good as we want to make it stable, not to stand the robot up from laying position. Yet, it still depends on other factors, such as the weight of the robot, center of gravity, wheel size, etc.

Suggestion: SPG50-20K

but it not come with encoder, is it SPG30E-30K ok?

Balancing does not necessary need encoder, but of course encoder will help a lot. Sure, you can try the SPG30E.

one thing more, is it possible to feed kalman filter into PIC16?

we have port the Kalman filter into PIC18F before, never try PIC16F before, but I believe it can be done.

i decide to use SPG30E-30K
but the item are out of stock.
So when the item will re stock up?

Just checked with our purchaser, estimated next week it will be re-stock.

is it have different if using 3x 3.7V 1100mAh Li-Ion Battery and LiPo Rechargeable Battery 11.1V 2200mAH
in term of speed or torque?
seems 20k 185rpm not enough in balancing if using 3x 3.7V 1100mAh Li-Ion Battery

really need help, now program with propotional gain, seems motor not enough,
