Im working in the control of an hexapod, and i think that its almost done… now i will try to build a body to test the controller…
my doubt is that i was reading about of the servos that you recommend and i realize that all of you think that the best servos are the 645 (and only for the coxa the 475), but i think that the 475 are strong enough (is that rigth??). besides the 645 are to expensive, i think that i can’t buy 12 o 18 of those.
i know that 645 has metal gears…
can i make my hexapod only with 475’s?
what are the risks of using 475’s for all the body?
some hex’s will work with 475’s but MOST are 645! … (There Are Reasons Why)
i had the old yellow lexan hex and it used only 475’s (as recomended) but even pushing it can course the servos to rupture! i shredded three servos by accidently knocking it into something or catching it!
i would buy what is recomended for the type of hex you want, but if you wish to make it last i would recommend 645’s for all joints!
you can sometimes pick up 645’s from ebay. i got one for £12, but i needed to replace the wire! works fine.
you get what you pay for with servos so cutting corners and being cheap wont do you any favour’s!
best off saving up and maybe get one at a time…
Welcome to an expensive hobby!
this could be doen to structural design. eg. leg length, servo horn contact, and the fact that the servos are not supported by SES brackets, so there are no ball barings???
so, i’t can walk with 475’s ??? i really don’t have money to buy the 645’s (but… maybe if i do another hexapod )…for now i will try to get 12 475 servos…
Specifically it’s the shorter femur (from hip to knee) length that allows the use of 475 servos on the *H3-R robots. The Phoenix femur is almost 50% longer than the *H3-R femur.
)…for now i will try to get 12 475 servos…
