Robot is a nanobot with a serious attitude problem. He's grumpy, selfish, and grossed out by the human body. His single goal in life-solitude. He dreams of spending his days in a dry, quiet place far from the mess of living things. But when an accident traps him inside the bloodstream of a middle school student, Robot's only goal is to escape before his battery runs out!

Red has a habit of making friends with anyone, no matter what kind of cell they are. He is fascinated by the world around him and sees beauty in the very things that make Robot gag. As they travel through blood vessels, making oxygen deliveries, they face bullies, germs, and immune cells. With his energy draining and no way to stop the glitches that take over his hardware, Robot must find a way out of the body before his system completely crashes. A story of biology, discovery, and friendship. Get ready for a wild, funny, and heart-pumping adventure in Robot and Red: Blood Bytes!
