"Bomb removal, Atomic disater cleanup, space exploration, mining disaster recovery..."
All of which are being done by specialized robots, or teleoperated machines. (The distinction isn't always clear - is a Mars rover a robot?) Those robots have forms that fit their functions far better than a humanoid form would. I'd argue that for almost any purpose, other than variations on the sex toy theme, a non-humaniod form would be better suited to the job.
"...eliminating the wheel chair"
This one I don't understand. Are you perhaps thinking of a powered exoskeleton? But that would not be any kind of robot.
"Both Honda and Toyota are building them first to be "partner robots"...
See? Sex toys, basically
"...the other major aspect is cheap labour."
It's far cheaper to just automate the job in the first place. (Or export it to China...) Using humanoid robots instead? Well, the closest analogy I can think of is if the first automobile makers had instead produced mechanical horses that you hitched to your existing buggy. Sure, it could be done, but is it the most effective way?
