Just a comparison…
What does your SES robot weigh ? I’m talking about a robot built with mainly SES brackets and chassis plus battery and MCU/servo controller etc.
My T-Hex comes out at 3.6 Kilos that’s about 5 and 3 quarter pounds.
I’ve seen 22 views to this post…what’s up 
you don’t have a bot you don’t have a scale 
I’ve got several PM’s on youtube about specs. This is what I give them:
(i dont have a bot … yet … 8) )
Thanks so far…just trying to get a comparison of the different bots and perhaps how many in use at this time.
But you will soon…
I don’t have a scale
My Archer 2*6DOF biped is 1,6kg.
Iron vulture biped 2x6dof= 4lb.2oz
Iron Wolf Quadruped 4x4dof= 5lb.1oz
ID3 3dof Indirect Drive hexapod = 4lb 10oz
Just a quick question. What accounts for the bulk of the weight on these robots? Is it batteries and servo’s, or something else?
-1
i would say the main bulk of the weight comes from the servos. in fact id prob say they account for 2/3rds of the weight. the battery weight can vary quite a bit but they also play a big factor in total weight.
when putting the ses together i always think that adding servos and battery’s will triple the weight of the ses frame.
Agree. But the servos alone is about 1/2 (more or less) of the total weight.
A 645MG with metal horn is 58 gram, but servos won’t work alone so if the SES parts are accounted as a part of the servo you would be correct about the 2/3.
This also work for a non SES project like A-Pod: Total weight = 3,3 kg, Servos 25 x 58 gr = 1,45 kg. That makes them even less than half the weight.
I think you find out a lot of this just from the specs on the website.
I slightly lied in the previous post. I do have a digital kitchen scale…
So if you look at my phoenix it weighs about 4.3 pounds.
It has 12 645mg servos which by spec weigh 1.94oz each or about: 1.46 pounds
6 485mg servos: 1.59 *6 = .6 pounds
I have a 2800mah 6 v battery = .58 pounds
So between servos and battery: 2.64 pounds, which leaves about 1.66 pounds left.
Again from the specs: the chaises weight about .5 pounds
Again the phoenix leg kits without servo about .4 pounds *3 = 1.2 pounds
Arc32: .13 pounds.
So about 1.8 pounds for chassis legs and electronics. Which is a little higher than measured, but should give you a reasonable idea.
Hope that helps

Note
Again rough numbers but
So far from what I’m seeing most of these bots are all coming out at about 4 to 6 lbs, mine is on the heavier side possibly because of extras compared to most.
I’m using 6 Hitec 5645 MG’s and 12 Hextronic HX12K’s ( got them from HONK KONG )
besides the servo’s I’m carrying…
2 - X-Bee’s with adapter boards with 2 SES brackets
1 - 4000 Ma. lipo
1 - Ping sensor with 1 extra servo and 1 SES bracket
1 - IRPD
1 - UBEC
1- mini cooling fan
and I’m continuing to add more
So far there is no lack of power/strength of the T-Hex 3DOF
You ever post images of this bot? 8)
I forgot to mention in the last one that my CHR-3 weighed 5lb 9oz (5.625)
It uses all 645mgs (so about 2.18 pounds for the servos)
It has a 2800mah and a 1600mah battery (.58 + .32) = .9 pounds
Again about 1.2 pounds for leg kits + fudge for contact switches…
Body Kit: .66
SSC-32: .13
Arc32: .13
XBee+Sparkfun adapter (.02)
= 5.18 so far I have accounted for about .5 pounds. Things that I did not account for included some standoffs that I used to hold the SSC-32, plus another set for Arc32 + one for XBee, Other wires like second wiring harness (.04), radio shack speaker (.02)…

Not yet, will do before the days done.
I’m not setup for good picture taking but here’s what I have.

Impressing !!!
Impressive!
I especially like the neat cable work you’ve done.
I’d say you’re pretty good at photography!
