This is an older composite set of sketches that I meant to post quite a while ago but overlooked. These are all characters I designed for a video game concept with a friend of mine a couple of years back. I still love these designs, and frequently considered revisiting them!
All of the robot designs are based on foraminifera, or “forams” which are the microscopic shells of organisms that geologists use to date sedimentary rocks. The little robot in the upper right corner is named GRUBER, which is an abbreviation of Globigerinoides ruber.
