Energy storage robotic arm

What is a robot arm used for?

The arm can be used for electrically driven transport of molecules or nanoparticles over tens of nanometers, which is useful for the control of photonic and plasmonic processes. Application of piconewton forces by the robot arm is demonstrated in force-induced DNA duplex melting experiments.

How does a robotic arm interact with a platform?

The arm motion is further modulated by the local energy landscape that governs the interactions between robotic arm and platform, triggering spontaneous skipping events at preferred orientations.

How does a nanorobotic arm work?

Initially, the arm follows the electric field rotation. When reaching the limit of its RoM, the nanorobotic arm stalls, while the electric field rotates further. With increasing phase difference, the arm is favoured to rotate in the opposite direction to align again with the external field, thereby reducing the tension within the joint.

How many NT nucleotides does a robotic arm have?

The median RoM obtained from a large number of measurements on individual robotic arms increased linearly with the number of nucleotides ( N) in the spring domain for the 3, 7 and 13 nt variants, with a maximum value of approximately 15π (that is, 7.5 turns) for the 13 nt variant (Fig. 3c ).

Does stacking influence enthalpic energy storage?

Brownian dynamics simulations suggest that breaking of stacking interactions is a major contributor to enthalpic energy storage. The molecular joint of a nanorobotic arm can be wound up to store mechanical energy and then relaxed to drive the rotation of a DNA nanodevice.

How does a nanorobotic arm reset a molecular joint?

As the nanorobotic arm is rotated from its resting position by an angle φc, the two domains wind around each other and create a resetting torque τsp = − kφc, where k denotes the torsional spring constant of the molecular joint, whereby we assume an ideal torsion spring.
