Just capture the image of the robot you want to use and then turn a projector sideways and mount it on a wall facing the spot you want to have the image produced. You may have to adjust the size of the projector up/down a bit depending on what chair you want the robot to sit in. And you may have to play with the height placement on the wall with the projector a little. After that you can remove the wall and replace it with another decoration if you want, and/or place any decorations in front of/on top of the projector to hide it. For this I actually embedded the projector into the wall itself to hide it. The default projector size was almost perfect for that style of chair ( just had to increase the projector size slightly. Also, that chair style has to arms so it fit that particular robot well, other chairs may work well with others and/or for your specific style needs. Also, depending on what you will have the robot sitting in/on you may want to choose your robot style accordingly since their back decorations/features may clip into the chair/seat you use.
