Robotics conference ROSCon hired me to create a tshirt design for their bi-annual event. This Fall, ROSCon will be held in Chicago so they wanted something specific to the area. ROS is robotics programming language and its mascot is a turtle. Lots of their imagery and branding is turtle-related. There's even a robot that runs on ROS called Turtlebot. So, for my design, I have a turtle taking a walk with a Turtlebot in an imagined park somewhere near downtown. The colors are always nice in that part of the country during the Fall months and I wanted to reflect that in the design, so I used orange and off-white on a maroon colored shirt. Below is the original sketch for the shirt artwork.
