Human Sized Robot

is there any way to connect with someone experienced with building and remotely controlling a large robot for collaboration on a commercial project?

Leonardo46: very fitting ID for inventor in Italy:). thx for commenting. Doesn't need to be walking, could be on wheels, like electric wheelchair or hoverboard; allows use of their large battery type which lowers centre of gravity. 
In fact, I have begun wondering if lifting 10 lbs/5kg could be done using a hoisting wire that would be powered by the same motor that turns the wheels axle and would only engage when wheels were disengaged (type of transmission??)
To move on wheels is much easier. There are many examples of such robots around.
For the arms you might use cheap geared motors  adding position sensors for feedback, or linear actuators (Servocity makes many types, with their own control system) or rotary  servos with very high torque (I saw one with 280 kg.cm).
Leonardo is my first name.
For weight distribution of carrying large loads, Boston Dynamics has demonstrated the easiest application. The trouble with humans imagining robots is that we imagine them looking like humans. The challenge with that is humans are actually quite terrible at specific tasks, and are instead merely competent at a wide variety of tasks. For example, the worst robot lawn mower you could design is a human:)

Here's boston dynamic's box stacking robot... Notice the counter weight to assist with it's inverted pendulum balance.

If you want a cheap hack for high torque you can always use a hacked battery drill and booker rod instead of a rotary servo for a fraction of the price. Here is Bruton's robot legs, he originally used hacked drills for (he eventually replaced them with proper motors). Sounds like you are still in the early concept and design phase. I was surprised to hear you already have the software written.

DJ: honored to have attracted your attn. Wonderful point about thinking out-of-the-(human)box, so to speak, for the "look". A business person doesn't care what the device looks like, only that it can perform efficiently. On the other hand, a consumer may yes care (or not) - I think jury may be still out. (Of course, I had seen the Boston video you linked but hadn't articulated the message you found.)

All the applications I envision need primarily an app that can control the robot device (of whatever appearance), as you have achieved with your EZ stuff. One of these applications doesn't need a humanoid body, but does need to exert more torque than 19 kg/cm. My business plan for only this one application predicts that, with only a 1% penetration into existing installs in the US, the net revenue stream would be $112M/yr., ongoing from just that penetration. As I have said before (and demonstrated) I do not have the knowhow or inclination to build the necessary hardware. But, I do have the software ready to go and need a partner to fill the missing pieces, ie. construct a working prototype (if need be with only temporary fixes such as Nink's suggestion of "hacked battery drill and booker rod") that can be shown to prospective buyers, get whatever feedback to tweak and off to the races.

Did you create the software in Synthiam's EZ-Builder? Because that would make sense in how quickly you created it!
