These three posters were drawn by me using the iPad. Inspired by a poster from Pinterest and the thesis topic I studied. I have always been worried that people will be replaced by technology. As in the poster, people may appear in the vending machine (credit by Andrew Fairclough). When people become cheap goods, it is too late for us to regret the lazy life of relying on technology now. So I drew three posters, and these three posters are a progressive relationship. The first one was a child's face attached to the glass of vending machine, looking inside the robotic arm and feeling the magic of technology, and the second was vending machine turned into a thoughtful robot control, when humans open vending machine, is a thoughtful robot brain. The third poster is a man who is completely replaced by a robot and who pays for it into a robotic arm.
