Abstract
Purpose
The motivation for robotics research in the agricultural field has sparked in consequence of the increasing world population and decreasing agricultural labor availability. This paper aims to analyze the state of the art of pruning and harvesting manipulators used in agriculture.
Design/methodology/approach
A research was performed on papers that corresponded to specific keywords. Ten papers were selected based on a set of attributes that made them adequate for review.
Findings
The pruning manipulators were used in two different scenarios: grapevines and apple trees. These manipulators showed that a light-controlled environment could reduce visual errors and that prismatic joints on the manipulator are advantageous to obtain a higher reach. The harvesting manipulators were used for three types of fruits: strawberries, tomatoes and apples. These manipulators revealed that different kinematic configurations are required for different kinds of end-effectors, as some of these tools only require movement in the horizontal axis and others are required to reach the target with a broad range of orientations.
Originality/value
This work serves to reduce the gap in the literature regarding agricultural manipulators and will support new developments of novel solutions related to agricultural robotic grasping and manipulation.

Abstract
Purpose
Fans are proactive consumers of pop culture products, who can be seen as prosumers. Fanvideo production is one of their most widespread practices in the participatory culture scenario. Thus, the aim of the present study is to analyze how ludic prosumption is featured on plays performed in Brazilian fanvideos based on successful pop culture franchises.
Design/methodology/approach
Research based on the interpretive content analysis of fanvideos of plays produced by Brazilian fans based on five emblematic pop culture franchises and published on YouTube.
Findings
Results have shown six play types in the analyzed fanvideos – i.e. child's play, performing powers, cosplay, play in social rites, teaching to play and “zuêra” –, which revealed a way of having fun in different situations through different practices based on ludic consumption experiences in different spheres of social life.
Originality/value
CCT-based studies focused on investigating plays as ludic consumption phenomenon, as well as fan culture, remain at early research stage. Thus, the main contribution of the present study lies on associating such concepts based on the concept of prosumption.
