A Robotic Percussive Aerophone
Abstract
Percussive aerophones are configurable, modular, scalable, and can be
constructed from readily-available materials. They can produce rich
timbres, a wide range of pitches and complex polyphony. Their use by
humans, famously by the Blue Man Group, inspired us to build an
electromechanically-actuated version of the instrument in order to
explore the expressive possibilities enabled by machines. The Music,
Perception, and Robotics Lab at WPI has iteratively designed, built
and composed for a robotic percussive aerophone since 2015, which
has both taught lessons in actuation and revealed promising musical
capabilities of the instrument.
... This licence ensures that any modifications made to the design are contributed back to the community, but also allows non-open products to use it unmodified as a subcomponent. Only a few robot musicians have been fully open sourced such as the guitar [3], violin [4], and percussive aerophone [5] family of instruments. There is a gap in the OSH robot orchestra for a woodwind family system. ...
... Thus, it can be clearly seen whether both culture and company size affect perceptions of human resource employees and managers towards AI. Sundberg (2018) claimed that the economic cost of the traditional recruitment process to the organization was quite high. Dirican (2015) also stated that the economic cost of using AI technologies in organizations could be quite high. ...
Purpose
The aim of this study is to develop a reliable and valid scale. At the same time, it is to reveal the perceptions of HR employees towards artificial intelligence (AI). In addition, examining the change made by AI in the HR department is another purpose of the study.
Design/methodology/approach
A scale was developed in this study. A total of 821 observation out of the samples from the human resource managers and employees of the Turkey's largest organizations in terms of capital were analyzed by applying all scientific steps of scale development process. Using appropriate statistical criteria, scale was showed to be valid and reliable. General condition was demonstrated in the human resource departments of large companies in Turkey as a result of these tests.
Findings
Human resource employees and managers could have the perception that this technology will save the work done from monotony, reduce the stress experienced to find the suitable candidate and access more candidates with the desired qualifications. It was found that when AI technology was included in training and development process, human resource managers and employees could have a perception that the time spent for training and the lack of attention in training will decrease compared to the traditional method.
Originality/value
The contribution of this study to the literature is the development of a valid and reliable scale. Data collected with the developed scale were evaluated in Turkey.
The field of musical robotics presents an interesting case study of the intersection between creativity and robotics. While the potential for machines to express creativity represents an important issue in the field of robotics and AI, this subject is especially relevant in the case of machines that replicate human activities that are traditionally associated with creativity, such as music making. There are several different approaches that fall under the broad category of musical robotics, and creativity is expressed differently based on the design and goals of each approach. By exploring elements of anthropomorphic form, capacity for sonic nuance, control, and musical output, this article evaluates the locus of creativity in six of the most prominent approaches to musical robots, including: 1) nonspecialized anthropomorphic robots that can play musical instruments, 2) specialized anthropomorphic robots that model the physical actions of human musicians, 3) semi-anthropomorphic robotic musicians, 4) non-anthropomorphic robotic instruments, 5) cooperative musical robots, and 6) individual actuators used for their own sound production capabilities.
Solenoids are important components of robotic drumming systems and several designs have been proposed. In this paper, we compare different designs in terms of speed and dynamic range and discuss the tradeoffs involved. The evaluation is performed in the context of MahaDeviBot, a custom built 12-armed MIDI controlled mechanical device that performs a variety of Indian folk instruments, including frame-drums, bells, and shakers. To measure speed and dynamic range a haptic robotic feedback system using piezo sensors was built. The evaluation methods presented are modular and can be administered to any hyperinstrument, new interface or robotic system to inform composers about the strengths and limitation of different designs to guide composition and performance.
In this work we describe a MEMS instrument that resonates at audible frequencies, and with which music can be made. The sounds are generated by mechanical resonators and capacitive displacement sensors. Damping by air scales unfavourably for generating audible frequencies with small devices. Therefore a vacuum of 1.5 mbar is used to increase the quality factor and consequently the duration of the sounds to around 0.25 s. The instrument will be demonstrated during the MME 2010 conference opening, in a musical composition especially made for the occasion.
