Tachyon's First Robot
I was in Calgary for Comic Con and I met DJ Sures. I was impressed with EZ-B and I bought the EZ-Robot kit. I only just...
Rich's The Testbot
So my second EZ-Kit turns up and rather than start a strip down of Wall-E or Omnibot like I had planned I decided to...
DJ's Revolution Snake
I dived into the box fresh injection molded parts from our manufacturer tonight and built this EZ-Robot Revolution...
WOW 2 EZ-B? you have overloaded your Buster for sure
but he's coolest bot i've seen, must be crazy with the scripts and all to get everything function like that. More details please!
That is part of my problem. I have had him finished now for several months but as soon as I fix his sholder moter one of his hand servos goes south and so on and so forth. Been through 8 servos 4 h-bridges 4 sholder motors 2 transister switches and now I have to fix his sholder limit swithches and another hand servo. If I can get to the point where everything works for a week end I will be able to make a video which has been my goal for the past two months.
Ouch. That has got to be frustrating.
Will try to be patient. I apologize in advance if the female comes out in me. :o)
BTW is there any other females on here? I don't think I have run across any.
Nope , you are the smurfett of ezrobot
HI Bookmaker .
You my have to invest in some metal gear servos for the most heavly loaded joints in the arms. Exspensive but should last for years , So a good investment .

PS love the left arm (gripper + gun + flamethower) How about a cattle prod .
I have 645mg hitec servos that are pretty good at 133 oz in for general movement like the head.,,h itec 995 mg that have even more torque , 208 oz in 6v , 34.99 Specifically from robotics website , 260 oz in torque , 19.99 , great sweet spot , price vs performance. http://www.pololu.com/catalog/product/1057
Even if your servo stalls , having metal gears means they are less likely to be damaged and more likely to just stop moving.
Something I.am.doing.you may want to think about is using two servos in tandem to handle the servo stress vs one. , two cheap $20 servos like from pololu could grant you 520 oz in torque from $40 but still have a snappy movement rate , each servo would carry the exact same signal , splice the wire. , I plan the same mad scientists idea for the elbows as well so my bot won't have problems picking stuff up.
I used Savox servos, they're incredibly high quality at great price comparing to Hitec and other brands.
This is a strongest one at good speed:
Savox SA-1283SG SUPER TORQUE Steel Gear Standard Digital servo .13sec/416.6oz-in
This is excellent for general movements:
Savox SC-0251MG Larger Standard High Torque Metal Gear Digital servo .18sec/222.2oz-in
Woo those are expensive to be burning out.
