Is there a 'thing' that I can use to use the GPIO pins on my B+ without soldering and without a breadboard?

I know I could use a breakout board with a ribbon cable and breadboard, but that adds an extra ribbon cable and breadboard. Does something exist which is like a breadboard I can just plonk on top of the GPIO pins without soldering onto the GPIO pins?

The reason I want this is because I want to be able to reuse my pi for other GPIO projects, but at the same time, I don't want to add unnecessary weight to my robot!

It doesn't need to be something that is permanent - just something that would work for a few months.

I hope you understand what I mean - if not, please ask me for more information!

There's this, but it's pretty hard to beat a regular breadboard for prototyping. If you don't want to use all the pins or a ribbon cable you could just get a bunch of these to make individual connections with no soldering. You can also first make your circuit up on a breadboard, and when you get it how you want it make a permanent board, which would be light and compact.

Check out Grove connectors. No breadboard. Just plugs you can not plug in backwards. Here is a tutorial on using Grove connectors:
