Hi all! I'm excited to share this project with you, this is the robot RSP, I bought my second ez-b (v3) and having checked with my first robot(MY ROBOT)
, I decided to undertake a larger project, its height will be of 5.4 feet (1.65 m), currently under construction I have the head, and gathered the materials for the traction system, some voltage regulators, 2 rc esc, several batteries, etc..
I enclose a drawing of how it will look when completed and some photos and video. I hope this project will have a mutual sense of teaching and learning for the entire community that will inspire others and that I may be inspired by all your valuable ideas, more information soon.

Hey Everyone - happy new year! I figured I would share some of my hilarious progress so far, having received my dream...
My regulators are self-built and based on LM317, had several at home and decided to use them, but sell them for $ 5.40 shipping facts included with up to 3 amps of consumption, although I recommend mounting a heat sink on them . You can find many cheap regulators ebay if you search the words dc-dc converter.

Are you the one who is selling them on EBAY? I do have some of the LM317 regulators and heat sinks at home already. I think I will build the circuits like you did and try that. Do you think I will need a cooling fan?
Thanks
Yes, put a cooling fan on your electronics because.they.get.hot
In my case I did not need a fan, the cooler is great and works well, but if you put fan no problem. I am not the eBay seller, I have only seen these regulators as cheap as buying the components and the board and make them yourself. This is the scheme, simply replace r2 by a potentiometer resistance of 2200 ohms.
Hi R2D2,
I'm eagerly looking for your robotic hand servo modification. If possible, make some videos. I'll continue with my robot within a few weeks when I'm back from my holiday. A robotarm/hand extension is one of my extensions.
Greetz,

Thanks R2D2. I tried the circuit and it works great. I will build four circuits; 9V, 6V, 5V, and 3.3v. Next I will have to figure out how to lay this all out neatly and add terminal blocks.
PHG: I guess I'll have more in a hand at home, but if I have very clear what I will do with it. -First cut the excess plastic behind the toes and build a palm-size. -Cut the union also thumb finger and tilt inward to grasp objects with the original design is quite poor, I'm thinking of making a tilt adjustable system that can fix your position with a screw, so I can taste the position more effective. -Then in hand mount two servos that I have and connect to the fingers (all the fingers except the index finger are connected to a mini 3kg sevo) and separate your index finger of 1.8 kg micro servo. (with this combination of two servos can grab objects, pointing and waving)
Someone already put this hand servos but my modification is much more elegant ...
