Im trying to revive an old project that was put aside since 2008/2009.
A close friend sold me a ridiculous deal (hard for me to pass it) on some Hitec HV servo from his failed Jet Airplane project.
I got 6 HS-7245MH HV servos to use for Coxa joints and 6 HS-7954SH HV to use on Femur joints. Have not decide on the Tibia's servos yet (this i have to buy my own).
I have the older combo board (with p.Brain-HexEngine)
1) p.Brain-SMB V1.0 Motherboard
2) p.Brain-ds24 Robot Controller - (p.Brain-HexEngine).
My question is could i get away with lower torque/speed servos for the Tibia joints? Or i have to match the servo i use for my Femur joints (HS-7954SH)?
Since i'm using Matt's HexEngine firmware, will there be problem with walking gate, timing, etc.... with slower servo speed on the tibia joint compare to faster speed on the femur joint?
Need to use High Voltage servo, so i can 7.4 LiPoly battery for all the servos and separate 9V battery (step down by p.Brain-motherboard) for the boards.
I was thinking of getting 6 HS-5685MH servos for the Tibia's joint. Spec below: -
Speed: 6.0V, 0.20 sec/60°
7.4V, 0.17 sec/60°
Torque: 6.0V, 157 oz-in (8.8 kg-cm)
7.4V, 179 oz-in (10 kg-cm)
Weight: 2.1oz (60g)
Speed: 6.0V, 0.15 sec/60°
7.4V, 0.12 sec/60°
Torque: 6.0V, 333 oz/in
7.4V, 403 oz/in
Weight: 2.30oz (65.2g)
