Thanks for this information! Our rino tread also has a cupcake smell. try smelling your bolder - you'll see it smells like cheesecake. Considering the difficult visibility, our team is planning to utilize smell to help us get a sense of where balls and robots with rinotread are on the field. We are still prototyping, but it is coming along nicely. Bellow is what we have so far if you are interested.
