while building my first nasty funny robot arm, i've searched in google and youtube in the past few days.
i found... CBM
ok... then after reading many articles which made me dizzy and doubt, pls give me enlightenment or direction.
is CBM, simple CBM for robot arm, as simply put 2 shock absorber for connecting between 2 joints? (i'm not talking that $100K kuka well developed arm).
if so then, i will simply just buy a pair of rear shock absorber for small motor like 100cc motor, and link between shoulder and elbow, which is in my basic calculation, those 2 links will suffer the heaviest torque when lifting.
i'll attach a picture to make this clear.
does it make sense? or it's useless?
counter balance mechanism.
for me, it sounds like mechanical design to reduce the required torque.
i was thinking to power each joint with a big torque servo, like 180kgcm servo, to make the arm move smoothly. even i'm thinking to use double servo to move the shoulder part, expecting 70-90% of total torque in shoulder.
until i read about CBM, then... i'm dizzy now although i do have a hope if anyone here can give me a clue about that smart arm design or CBM.
hahaha....
i'm sorry. but i'm really a newbie in building robot.
my choice is only to learn anything (such as that fancy CBM) to reduce the required torque on the shoulder.
of course.... buy a bigger servo is always an option. add more $$$ to spend
unfortunately i can't find any cheap hobby servo bigger than 180kgcm (with 12bit magnetic encoder) and easy to code using arduino IDE.
that's why i came here for CBM and asking could it be CBM as simply as adding that funny spring or shock absorber?
so far as i found by now, CBM is about posture of the robot to reduce the required torque.
wrong again?
