robophilo

I am with techmech on this. a lil more cash for a lot better bot

If they had included the SV4140 servos in the hips, knees, and upper and lower legs and charged $100 more it would have made for a big improvement. Now that upgrade is going to cost us $244. Wouldn't it be nice if they offered some sort of trade in on the SV4032's? A bigger battery would have been nice too, maybe an 1100 mAh 7.2v.

guys check out the vid on the forum. let me know that you think...

[jaybirdtke]

Cool idea. Have you got any poses or motions programmed yet? Have you tried putting the bioloid actuators in the RoboPhilo?

[kinglasserres]

i just finishing it still trying to figure out how to build the back cover. i don;t think the acuator for the bioloid will work on the philo PCB.

Questions:

1) Does the robophilo use standard size servos?

2) Are the servo brackets and connectors strong enough to handle a more powerful servo such as the HSR 5990TG?

[jaybirdtke]

Yes, they are standard servos. specs below at 6V
(2)Feet Servos 6.5kg-cm Torque, .16 Speed
(15)Legs/Arms 4.1kg-cm Torque, .19 Speed
(3)Head/Leg Turn 1.3kg-cm Torque, .12 Speed

If you're going to invest US$125 per servo I would go with aluminum.

can someone tell me why hs55 servos will work but my s3003 servos wont?
weird

[jaybirdtke]

The only thing I can think of is Amps. the S3003 may need more than can be provided but I haven't found any data to support this.

[jaybirdtke]

I broke a tooth on one of the servo gears in his right shoulder. I was messing around with the (Speed, Mode, Step) of the servo states and somehow he got tangled up. I was planning on upgrading the hip servos, so I could use the gears from one of the originals to replace the broken gear in the should, however If I'm going to disassemble the entire torso to get at the hip servos, I might as well replace the shoulder servos too. I'm just waiting on robobrothers to offer the brackets which I'll need to upgrade the hips with the SV4140 higher torque servos. This upgrade should cost $111.00 plus shipping. Bringing my grand total to just under $550 shipped. Still a bargain.

trey3670, did you ever get that Futaba S3003 servo to work?

[trey3670]

yes I did as it turns out it was a bad servo,needed re-soldering

[jaybirdtke]

I just replaced the shoulder servos with the same S3003 servos and they work and fit just fine.

[trey3670]

more torque right? do you like them better?

[jaybirdtke]

The S3003 have the same torque as the SV4032 but they are quicker, according to the specs.
SV4032 - torque = 4.1, speed = .19
S3003 --- torque = 4.1, speed = .16
