Research on a Map-Based Cooperative Navigation System for Spraying–Dosing Robot Group

Agronomy, 2022
To solve the problem encountered when the spraying robot has run out of medicine even though the spraying task on the field is not complete, we developed a spraying–dosing robot group and proposed a collaborative navigation system based on an orchard map.

Channel-Optimized Vector Quantizer Design for Compressed Sensing Measurements

, 2013
We consider vector-quantized (VQ) transmission of compressed sensing (CS) measurements over noisy channels. Adopting mean-square error (MSE) criterion to measure the distortion between a sparse vector and its reconstruction, we derive channel-optimized ...
