“…Thus, there is ambiguity about the best harvest time for obtaining optimal functional effects [7]. Firouzi and Azarian showed that timely pruning of tea bush has desirable effects on the quantity and quality of the final product, and tea bushes are pruned in three forms of light prune, medium prune, and collar prune [8].…”

Catechins are one of the secondary metabolites contained in tea leaves. Cultivation practices such as pruning affect the shoot production and quality of tea yield. The use of plant growth regulators is a new breakthrough in tea plant engineering. This research aims to determine the interaction effect of type, height of pruning, and concentration of Benzil Amino Purine (BAP) and Gibberellin (GA) concentrations on tea plants' growth and catechin content after pruning. The experiment was conducted at Tea and Cinchona Research Centre Gambung in June 2018 until October 2018, with a split-plot design consisted of three factors as followed: main factor (a) type of pruning (clean and lung pruning); subfactor (b) pruning height (40 cm, 50 cm, and 60 cm); sub-sub factor (h) plant growth regulator (0 ppm, 60 ppm BAP, 50 ppm GA, 60 ppm BAP + 50 ppm GA). The result showed that 60 cm pruning and 60 ppm BAP in the third month after pruning significantly affected the chlorophyll content index (91,58I cci). There was an interaction between the pruning height of 60 cm and 50 ppm GA on fresh shoots weight per bush on the fourth plucking. Based on the response curve, at clean pruning, the optimum value at pruning height of 51.5 cm and 66,63 ppm BAP contributes to the catechin content of 1.88% while at lung pruning, the minimum value pruning height of 50.73 cm and 7.238 ppm with catechin content of 0.776%.

Accurately obtaining the posture and spatial position of tea buds through machine vision and other technologies is difficult due to the small size, different shapes, and complex growth environment of tea buds. Therefore, end effectors are prone to problems, such as picking omission and picking error. This study designs a picking end effector based on negative pressure guidance for famous tea. This end effector uses negative pressure to guide tea buds in a top-down manner, thereby correcting their posture and spatial position. Therefore, the designed end effector has deviation tolerance performance that can improve the picking success rate. The pre-experiment is designed, the tip of apical bud is referred to as the descent position, and the negative pressure range is determined to be 0.6 to 0.9 kPa. A deviation tolerance orthogonal experiment is designed. Experimental results show that various experimental factors are ranked in terms of the significance level of the effect on the average success rate, and the significance ranking is as follows: negative pressure (P) > pipe diameter (D) > descent speed (V). An evaluation method of deviation tolerance performance is presented, and the optimal experiment factor-level combination is determined as: P = 0.9 kPa, D = 34 mm, V = 20 mm/s. Within the deviation range of a 10 mm radius, the average success rate of the negative pressure guidance of the end effector is 97.36%. The designed end effector can be applied to the intelligent picking of famous tea. This study can provide a reference for the design of similar picking end effectors for famous tea.
