Robot Concept Art

After a meeting with my group, we have generated an idea of having different type of robots which would help the main character to finish his mission (charge the ship or something). We have four types at the moment:

1. Moveable
    - a small-ish robot which you can carry it with you
2. Super Charge
    - a robot will charge you with extra energy which would allow you go further
3. With Legs
    - a small-ish robot which could go to the place you can't go
4. Environmental
    - a robot goes with you, meanwhile all the surrounding objects would be charged

Now here here is my concept art for these robots:

The Main Character Concept

A Combination of Moveable & With Legs

Super Charge

Environmental

P.S. The reason of I making them animal-ish is we want to try out different styles for our game, in order to figure out the most suitable one. Hence I designed them this way and hopefully my group will like it.
