Comments made by my parents suggest i'm getting a rad for my birthday june 14(celebrating sooner)
So I want to have a plan in place for what ill need to make the rad.
Diagram of possible rad
Upgrade to ARC Pro
Unleash your creativity with the power of easy robot programming using Synthiam ARC Pro
@techno pro , I would just use the stock motor on the arms opening band closing. They do their job well. You could use a H bridge or a couple switching transistors and diodes to control them. As far as a battery go with the 7.2 v 2s lipo. Technically you want 6 volt for servos but if you buy high torque most are compatible with 7 volts. Take in mind analog servos like Power HD 1501mg do not make a buzzing racket where digital ones makes a buzz under a load. Its mostly a preference both will do the job for you. Digital are said to be more accurate but when you get down to real world testing you wonder if that's true sometimes.
-EZ robot kit has your standard servos , ultrasonic, camera and ezb all together in one package $169.99
-Hbridge for the tracks - $15
-Lipo 2s battery pack 7.2 volts -under $20
-Darlington switching transistors , 4 x diodes and 2x 1k ohm resistors ( to control your arms) -around $20
-2 x pololu.com power HD 1501mg 240 oz in servos $19.99 each
nOTE: I would have one servo on each side of your waist one servo will be reversed in ARC and they work together. Because they are analog they want be constantly buzzing to hold the waist up. One servo at 240 oz might be fine for you if you want to do only one but it wouldn't have much "lifting power".
-Maybe 25 servo ext cables , they are cheap but you need them for connections from servos and motors to EZB. .50 each
Standoffs- x8 ( mount ezb and h bridge) - $6
Best total of the basics - $291
All you need after this is super glue, hot glue, dremel/rotary tool, assorted drill bits , soldering iron, solder assorted LEDs, PC speaker...
Really? The 19.99 high torque servo is too pricy? Lol that's a very low cost. The eZ robot store has a high torque servo that's is about 130 oz in torque I believe for 13 dollars. Go to hobby king.com and look at turnigy 2S batteries
Sorry I don't have one and my arms are in pieces (not my arms but the robots arms, my arms are fine
)
Ha ha ha.
so final plan:

I can see buying a second Hbridge for the arms. would save me a bit of $.
Not sure on what to do for the body tilt.
This is the servo you think I should use for body tilt? A little expensive for my blood! www.pololu.com/catalog/product/1057
I was looking at getting a jumper cable set. is it worth it?
Could you tell me how much the shipping for pan/tilt bracket would be on lynxmotion to southwestern ontario?
What would be the best bang for my buck battery type(with a charger)? Think 8.4v is a set voltage for this project.

how many servos do I need for the body tilt? just one of those power HD 1501mg 240 oz servos?
the pan and tilt bracket is good quality?
