Understanding human responses to errors in a collaborative human-robot selective harvesting task

Abstract: In this paper, a grounding framework is proposed that combines unsupervised and supervised grounding by extending an unsupervised grounding model with a mechanism to learn from explicit human teaching. To investigate whether explicit teaching improves the sample efficiency of the original model, both models are evaluated through an interaction experiment between a human tutor and a robot in which synonymous shape, color, and action words are grounded through geometric object characteristics, color histograms, … Show more

“…Interestingly, when a field experiment was conducted to evaluate in practice the impact of the synergy on a site-specific spraying application, the proposed collaborative spraying system demonstrated a 50% reduction in the utilized sprayed pesticide [ 63 ]. Preliminary laboratory experiments in [ 82 ] investigated the opinion of experienced and non- experienced groups on errors produced by machine learning algorithms in a synergistic task.…”

“…This process was first adopted several years ago and gave a good output in time consumption [124], but it has several disadvantages reported by fruit growers that fruit and plant damage occur due to applied detachment force. However, this problem is very limited in big canopy trees and hardy fruits but has a high impact on fragile fruit and plants [125]. Another problem in bulk harvesting is that the fruit detachment is carried out without the identification of single characteristics of fruit, so most of the harvested fruit is unripe.…”

“…In [24,25], an emulated cooperative strawberry recognition task was presented. In this work, a robot navigated the environment and relayed the images with the automatically recognized targets (together with the degrees of recognition confidence) to human test operators.…”
