Nanorobotics at USC

What is Nanorobotics?. Programmable assembly of nm-scale components either by manipulation with macro or micro devices, or by directed self-assembly.Design and fabrication of robots with overall dimensions at or below the mm range and made of nm-scale components.Programming and coordination of large numbers (swarms) of such nanorobots..

    1. Nanorobotics at USC

    3. Why Nanorobotics? Applications, especially biology, medicine and the environment. Robotic science: Different phenomena at the nanoscale: surface forces, quantum effects, … Environments with large spatial uncertainties. Dynamic environments, robustness, adaptability, … New trade-offs between computation, motion, communication, … New strategies, algorithms, software, hardware… Minimalist robotics. Swarm robotics.

    17. Do These PPy Nanofibers Change Volume? AFM tip is placed directly over one of the PPy nanofibers to measure real-time height changes in response to cycling of voltage. 100 nm diameter fibers. Explain the experimental setup, emphasize that the tip is placed directly over the surface to allow for real-time monitoring of height change in response to voltage cyclingExplain the experimental setup, emphasize that the tip is placed directly over the surface to allow for real-time monitoring of height change in response to voltage cycling

    18. Real-Time Actuation of 100nm PPy Nanofiber Explain graph, lower one first. Point out the drastic behavior difference as compared to the film actuation response that was just presented. Point out that actuation seems strange but peak sets correlate to voltage, and that the system is in transition. Possible explanation is the sensitivity of the nanofiber system to the diffusion process of the mobile ions involved, where as for bulk property collective response predominates what is observed.Explain graph, lower one first.
