What do you guys think…?
im planning on calling this hexapod =
[size=150]ID3h-r[/size]
simply,
InDirect 3dof Hexapod
?
I love it! 8)
Johnny,
Well, I completely forgot to order the 4" femurs when I ordered the large arm parts for this thread.
viewtopic.php?f=6&t=6300
I opened the box and couldn’t find them… I’m really sorry. I have been so busy lately… I will get them here and ship everything ASAP. 
no worrys. i did wonder.
i will email you the shipping address now to speed things up as and when they arrive. im also having a few probs with my internet connection. i find that kicking the wireless modem works. 
the arm looks cool. cant wait to see what plans you have with the new parts. 
4" long femur parts are ordered! Yes send the info. It won’t be long now. Very sorry for not being very good at my job. 
I botched this up pretty good. I will do my best to make it up.
I sent you an email last night.
i wouldn’t worry about apologizing for this, i understand you are busy and are doing your best. also with the terms of the agreement we have i cannot complain.
im real excited still and i hope it lives up to our expectations. my surgery is next Friday but i do have 6 weeks off work so plenty of time to get the project done.
Ummmmmm. i bet your doing your nut now.
i have been thinking of a new leg design for another project i have in mind. i will post details on this after we have completed the ID3h-r design.
I’m in a holding pattern for the 4" long femur parts. The ones I forgot to order before. When they are here, we’ll be a-holes over elbows getting this stuff sent out to ya. You’ll see… You’ll all see! 
lol… i do love your sense of humor Jim. 
This is an idea of what the dimensions may look like:
as you can see there is plenty of clearance.
Theoretically i have rotated the coxa servo 90º around and “attached” it with a “L” bracket so its more uniform and neat.
for this to happen though we would need to drill the SES hole pattern in the center of the ASB-13 plate.
Obviously this is using one of the first gen leg designs so things will look different and Jim’s input will also change a few factors.

it would be nice to build it up in 3D but most of the meshes available are not in the format i work with.
4" long femurs are here. Please make me a list of the items you think you will need for this little experiment. I will do the same. We will ship this week. I can say that because everything is here now.
hi jim, great news.
if we build to this design we would need the following.

This list is based on what i already have to what we would then need to complete it.
**Also it doesnt include the MXL Pulleys as im not sure if you made changes to how it was going to work.
regarding servos ill leave this up to you. **
i would say we would get away with using the hs485’s but like i said its up to you if you think it will need stronger ones. i suppose once you have the parts together you could do a combined weight and calculated what would be best.
also the length of the tibia tubing is also your decision. i would recommend as stated.
as i said i do have spares laying about so it would be a shame not to use these and have you ship that extra weight.
regarding the Ball Bearings i have used the same as my original design.
you may feel that the Ball Link Set – 4–40 might be better.
of course im not sure if there is any changes you wish to make so i can only calculate it to what i know.
Design idea. (based on the list)
To center the coxa servo in relation to the tip of the leg i propose this idea.

hope this helps.
PPPPS. Dont forget to send the Femurs… LOL that would be funny.
EDIT:
Also Atompro28, SSC and BotBoard etc. oops
here would be the complete list. does not include the Ps2 controller/receiver, battery. i will use these from my quad project.
to be honest i could even pop the electronics from my quad too. up to you.
list is to the lowest spec.

What does the body look like that would accomodate a leg like this? It seems like the horizontal range of motion might be somewhat limited.

the HBKR-BLK will fit to this design.
its a prof of concept and i have tried calculating the distance and rotation of the coxa and all looks fine. we will see.
It’s a very interesting leg design. I am looking forward to seeing this hexapod all assembled and moving around.

thanks. it was heavily inspired by Dr. Frank Nickols robot hexapods
Me and you both my friend.
I have plans to use Xan’s Phoenix V1.3 and i have already altered it to work with these legs.
I was thinking of using the powerpod program but i like the way 1.3 responds.
I have been speaking with Dr. Frank Nickols last month and he sent me his website address. since it was launched it has grown quite well. i have been kept updated about some of his/his student’s work. some very interesting ideas. reminds me of FESTO.

hi jim, do you have any thoughts on mounting the coxa this way?
the ideal thing about this is that the servo can be mounted so the leg is closer or further away from the chassis. im hoping that if we use this design that the servo can be mounted so that the leg sits closer to the chassis. it will be really nice if it works well that way.?

any thoughts?
That is certainly a good way to go. I’m putting the package together now. You will have enough parts to try several solutions. I will post the list of parts here soon. Thanks for your patience.
