wow! thatāsā¦special itās nice, I would do it if I had the money, thatās when Iāll have plenty of 5645ās and lotās of SES brackets, Iāll just have fun with that!
Very cool, wish I had enough SES parts and servos to even think of building it. Reminds me of the SpiderSapien hack, connecting a RoboSapien V1 with an N.S.E.C.T. toy, thought obviously much more robust. evosapien.com/robosapien-hack/nocturnal2/taxonomy/term/9
Yep itās using 32 servos! Iām going to see what I can do about making it completely functional! Because the Atom 28 is about full with the leg operating system I will most likely make it serial controlled instead of PS2. Then I can drop a second (master) Atom 28 on it with a Smirf to connect it to a laptop. Then the master Atom 28 can receive the instructions from the PC and tell the slave Atom 28 what the legs should be doing. To control the torso, it should be just a matter of wedging into the leg control program the ability to pass through some native SSC-32 positioning commands from the master. Note, this is of the top of my headā¦ I reserve the right to change my mind when I wake up all the way. lol
mnmm, 32 servos, pretty limit there , why canāt you make it PS2 with 2 Basic Atoms? would that be to complex? You realy need a laptop? Of, course, you can change you mind anytime!
People think Iām crazy for designing a 32 servo quadrapedā¦ Hmmm, me thinks I be not the only crazy person hereā¦
Youāll have to devise your own master/slave setup since the Atoms always expect to be masters on an i2C bus. That shouldnāt be difficult though, with a two or three bluetooth modules.
Just do it right and get a small Linux based microcomputer and program it all with Python. Or, you could build one of Peteās dual PIC boards and program it all in Cā¦
The hexapod is using HS-645 servos. The torso is 2.5lbs and with the battery the hexapod is carrying almost 3.5lbs payload. The hexapod has great difficulty getting up from the down position. Remember this is the āCā style leg, the longest, which because of the length is the weakest leg. The āBā style leg being the shortest, is the strongest. The HS-645ās are working pretty hard, but not self destruct hard. lol I think if the HS-5645ās were used in the legs it could lift the payload without issue.
This is not a kit. Itās too extreme for me to go that route. Itās just for us to create some videos, then take it apart.
I needs me that thar CH3-R because we had to ship my other one to the movie place.
After chatting with James I believe the problem is with his battery pack. It will run the bot just fine, but if trying to stand up from an idle position the SSC-32ās are resetting. So if we were to run it with a stronger pack, or dual packs it would probably lift the payload without problems.
It seems that this design would be an excellent candidate for the ādual packsā approach. One battery to power the mobility base, and a second to power just the torso on top.
You might be able to run with three lighter packs, like the 6V 1600mAH packs. One for each side of the SSC-32 running the CH3-R, and a third just for power to the SSC-32 running the Johnny 5 torso. Iām assuming a single SSC-32 runs the CH3-R, and another runs the torso only. This would be a great opportunity to see if this approach works, like what we talked about for powering my Walk 'N Roll project.
