I would like 5 renders of imagined mobile robots

Hello talented people.
I would like at least 5 renders of imagined mobile robots.
We have a Mobile Robot kit that looks like the render and photo below. This can be made into all sorts of mobile robot. Your task would be to design good quality renders of possible mobile robots. You have creative freedom to make the robot how you like, it could be a redesign of other robots you've seen but it should be:-
* Business like, a possible product a company or university has built using our base kit, not a Pixar character.
* Unbranded, no logos or appear too much like other robots you find in your research, and a little different from
each other.
* Should the undercarriage be visible, it should look like the attached frame has been used including the wheels but
you don't have to see the wheels. Don't worry too much about the shape of the base kit, this can be varied
* They should be diverse in appearance and have apparent uses or a suggestion they have a function , some squat,
low others might be tall or look fast!
As you can see, we have the skills in house to do this work, but at the moment they are crazy busy so we would like the files to use them in our Marketing work for brochures videos, animations etc.
A simple google image search for AMR Robot will reveal a huge variety.

Here's a video which would look good if we stopped it in the middle and showed the robot with some of your renders imposed.

I'm happy to answer questions to ease the process. We would prefer to work with someone we can use again for other campaigns.
I suppose a quote for each that we use would be ideal. If you come up with 3 usable ones, great but if you do 7 that we like we'll buy them all. Please let me know what type of files you will make available. I know our team use Solidworks and Adobe suite, so they should be compatible with these please.
Thank you

Update: Please see the new picture- this is one of our suppliers illustrating their product in use, they only make the motors. this is similar to what we need to do.
