My SoupHammer™ Servo driven by the HackJammer[R] board has been dramatically upgraded.
Behold the ultimate dual drive servo, capable of 14 N-m (theoretically estimated because it’s 3D printed of polymer and if I really get that much force the dynamic torque will chew up the plastic teeth inside).
The servo is driven by two symmetrical 100mm high-torque gimbals tied to the same axis.
Now I got to implement closed loop which is really tricky because I need to tie up a sensor on the outside.
Then I need a really big can of soup to test with.
All hail the SoupHammer™!!!
PS The HackJammer[R] is driving the two SoupHammer™ gimbals simultaneously with the same PWM but one is inverted. The other interesting point is that the resistance is halved (parallel coils). Also, this is at 12V. If you push 24V it could double the torque but will probably burn the coils.
