Viotar/Hardware Design

Introduction

The design progress of the hardware, meaning the actual instrument, is described here.

Design 0.1

On friday the 5th of november, the first attempt at a design was finished. Only geometric constraints were taken into account, meaning the size of the engines and actuators were solely adjusted to the amount of space that was available in the guitar.

Design 0.2

From reviewing design 0.1 with the group, the following points of improvement were determined:

• There is too little space for the engines, so their spacial configuration should be altered so that they can be bigger.
• There shouldn't be motors on the neck side of the construction, because that forces the construction towards the bridge, leaving less space for the player to pluck the strings.
• An estimation should be done on the size of the motors, based upon an estimation of the power that is required from them.

These improvements have been worked into design 0.2.
