Where finding powerful and special servomotors ?

-

hello,

i need special motors humanoid robot project reproduce movement https://upload.wikimedia.org/wikipedia/commons/2/2e/pronation_and_supination.jpg arm , others also, how call type of servo ? wanted know find powerful servo, looking around 1000kg.cm, ideas?

1000kgf-cm 100nm break you, far far more torque human wrist
can handle instance.  need fit axle nut road vehicle.  you
really know these torque values mean?

generally non-standard applications need build own gearmotor , position
feedback system, or spend money on industrial servomotor.  noone's going manufacturer
a vast range of servomechanisms match every possible robot articulation topology , size,
you either build standard parts or pay bespoke manufacture, implies
high volume production economic.

simple rough guide torque:

0.1nm = forefinger+thumb turning something
1nm = 1 hand driving screwdriver comfortably
10nm = 2 hands on car steering wheel

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
