Our Robot, "D-NApper"
We're making a molecular robot that can capture an object DNA and put it inside the robot.
Our robot has the function we named "Selector".
"Selector" is single-stranded DNA which has complementary sequences to the "Target DNA" here and there, and consecutive adenine sequences in other portion. We have three "Selectors", and the inner "Selector" attaches to the target more strongly. When "Selector 1" catches the "Target DNA", the left sequences (which are not complementary and do not attach to the object) make loops. Then the structure shrinks and becomes shorter.
Thanks to "Selector 1", the robot can select and draw the target DNA close to the robot. Next, "Selector 2" receives the target DNA from "Selector 1". And "Selector 3" receives the target from "Selector 2". Thanks to "Selector 2" and "Selector 3", the robot can deliver only the object inside certainly.
Then, we will explain the body structure containing these functions.
We design the robot like a tube of hexagonal base. In case it is too difficult to form and observe, we also design a triangle prism body. As for the latter shape, we made the same kind of structure last year. We've acquired some know-how of it.
We think the robot should have a lid so that nothing would come in from the back. So we arrange "Selectors" symmetrically.
