Objective: Under external environment stimuli, seedlings undergo variation of morphology and alterations in their genetic sequences. Phytochrome signaling, i.e., feedback reaction of plants to photons and other nutrient cycle plays a crucial role in its maturation. Method:In this research work, we create a cyber-physical system to control such morphogenesis of plants through the help of artificial intelligence framework which identifies and control the crucial feedback between plants' genetic transcription with respect to the external stimuli such as nutrients, electricity, and magnetism. Results and Discussion:This leads a plant to autonomously grow without its disadvantageous traits by destabilizing its negatively acting transcriptional regulators and enhance the plant's advantageous features by controlling its positively acting transcriptional regulators. This has led us to control the plant metabolism, plant growth without soil, manipulate the immunity of plant against disease, develop a plant metabolic profile, and maximize its yield deprived off from its seasonal attribute.

“…Due to the existence of well-organized nature, indoor cultivation provides a relatively easy environment for application of different automation plans (Edan et al, 2009), some of which are related to the controlled displacement and spacing of the growing plants. In this regard, moving the crop and increasing the distance between the adjacent plants through the spacing operation would be necessary, when unfavorable interferences between the growing leaves become dominant.…”

Purpose: To present a flexible and accurate autonomous solution for creating any desired row spacing value between the hydroponic gullies in multilayer growing units, and evaluate the capabilities and performance of the relevant automated system through the use of virtual prototyping technique. Methods: To build the virtual prototype of the system, CAD models of its different parts, including an autonomous vehicle and the mechanical mechanisms embedded in the multilayer growing unit, were developed and imported into the RecurDyn simulation software. In order to implement the automated row spacing operation, three spacing modes with different loading cycles and working steps were defined, and the operation of the system was simulated to obtain the target row spacing values specified for each of these modes. Results: Motion profiles related to the horizontal displacement of: 1) the lower and upper sliding bars installed in the cultivation layers, and 2) the hydroponic gullies, during the simulation of the system operation, were generated and analyzed. No deviation from the specified target spacing values was observed at the end of simulations for all spacing modes. Conclusions: The results of the motion analysis obtained by simulating the system operation confirm the effectiveness of the control scheme proposed for automated row spacing of gullies. It was also found that proper sequencing of the loading cycles and the precision of the working strokes of the upper bars are the critical factors for establishing a certain row spacing value. Based on the simulation results, precise control of the back and forth motions of the upper bars is highly necessary for sound operation of the real system.

Sound-based positioning systems are a potential alternative low-cost navigation system. Recently, we developed such an audible sound-based positioning system, based on a spread spectrum approach. It was shown to accurately localize a stationary object. Here, we extend this localization to a moving object by compensating for the Doppler shift associated with the object movement. Numerical simulations and experiments indicate that by compensating for the Doppler shift, the system can accurately determine the position of an object moving along a non-linear path. When the object moved in a circular path with an angular velocity of 0 to 1.3 rad/s, it could be localized to within 25 mm of the actual position. Experiments also showed the proposed system has a high noise tolerance of up to −25 dB signal-to-noise ratio (SNR) without compromising accuracy.
