I had the exact same issue as you about 6 months ago. I like robotics, but couldn't narrow it down to a particular project. I did in the end and it's been a blast.
I'd suggest you try and narrow down your interest even further
. The "tele-operation of humanoid robots" involves a rediculous number of things - mechanical, electrical, psycological!
I get a lot of inspiration from robotics blogs and news sites - they'll often report on some cutting-edge stuff and you'll think 'Hey, that would be useful in [xyz
]', or 'What if you combine that [widget
] with a [gizmo
Here's the few I frequent;http://spectrum.ieee.org/blog/automaton
[has a massive lost of blogs in the bottom right - the 'blog roll']http://www.robots-dreams.com/http://www.neurdon.com/http://robots.net/http://blog.trossenrobotics.com/http://www.hizook.com/
I suggest you read through those and see if they give you any ideas.
Once you've found something, try going to IEEExplore
and searching for it. If you're doing a degree then I'm sure your university has some subscription you can utilise. A lot of the papers may at first seem intimidating, but they're often very accessable. They can give you further inspiration.
If you want any more info, try being a bit more specific and I'll see if I can think of anything.
