Inlärning av trumrytmer, utlärd av en robot : Ett instruerande verktyg för nybörjare — att genomföra korrekta trumrytmer med realtidsfeedback (Swedish)
Abstract [en]

Accurate rhythmic pace-keeping is an ability achieved only by a lot of practice. However, finding the opportunity to practice can be difficult when availability of teachers is insufficient. This thesis aims to construct a prototype that teaches its users basic rhythm keeping, specifically rhythms produced on drums. To reproduce the behavior of a drumstick hitting a surface, a device was constructed, able to perform three different rhythms mechanically at the speeds of 100, 150 and, 200 BPM, using a drumstick attached to a servo. By adding a sound sensor, the device was also able to methodically track drumming inputs. By integrating a microcontroller and programming it accordingly, the user can practice rhythmic pace-keeping visually and audibly and receives real-time feedback on their performance through an LED interface. Furthermore, the device’s actual rhythmic abilities were measured and compared to its theoretical values, which showed very small to no deviations. A study showing that combining visual and auditory channels facilitate rhythmic learning abilities gave substantiation for a conclusion estimating the drum-bots utility as a satisfactory educative tool. In future work, the demand for this product could be quantified and studied.

Abstract [sv]

Noggrann rytmisk takthållning är en egenskap som uppnås endast genom mycket övning. Att finna möjligheten att öva kan dock vara svårt vid tillfällen då tillgängligheten av lärare inte räcker till. Detta examensarbete syftar mot att konstruera en prototyp av en apparat som lär användaren grundläggande rytmhållning, mer specifikt trumrytmer. En apparat kunstruerades som kunde utföra tre olika rytmer mekaniskt genom att använda sig av en trumstock som var fastmonterad i en servo. Hastigheter var 100, 150 och 200 Beats per minute (BPM). Genom att sedan programmera mikrokontrollern har användaren möjlighet att träna rytmisk takthållning visuellt och hörbart samt erhåller realtidsfeedback på prestandan via ett LED-gränssnitt. Dessutom mättes enhetens faktiskt rytmiska förmågor separat och jämfördes med de teoretiska värdena, vilket resulterade i mycket små eller inga avvikelser i prestandan. En studie som uppvisar att kombinationen av visuella och auditiva sinnen främjer den rhythmiska inlärningsförmågan, gav substans för en slutsats vilken uppsakttar trum-botens funktion att vara tillfredställande som ett inlärningsverktyg. I ett framtida arbete, skulle efterfrågan i en sådan produkt kunna kvantifieras och studeras.
