Mechanism Design for Haptic Handwriting Assistance Device

Abstract

One of the applications of haptic technology is in education and training. Handwriting for first year-elementary students has been included in the curriculum for some years in Turkey as the first and only writing skill to be taught. Providing these students with a haptic assistance device during the handwriting learning process is the global aim of this work. Among the other components of the design such as electronics, controls and communication, mechanism design is a critical component to be considered for optimization of the device at different levels. This paper aims to address a solution to meet the design criteria through ergonomic design for user along with optimized force exertion capabilities.

Design of a Linkage System to Write in Cursive

“…The contribution of this research is an extension of computeraided mechanism design techniques described by Sonawale and McCarthy [22] and Ge et al [23] to achieve devices that draw complex curves, which has a range of applications such as physical models for profile curves that define tolerance zones [24], kinematic models for protein movement [25], and mechanical devices that support handwriting rehabilitation [26,27] and handwriting recognition [28].…”

Digital Twin of a Servo Driver of a Servo Motor as a First Step Towards a Digital Twin of a Robot Mechanism

“…Since servo motor systems yield satisfactory results in position and velocity control applications, they are one of the highly preferred actuation systems in industrial appli-cations. For example, in [1] a macro -micro mechanism for laser cutting process has been designed with servo motor system so that the end -effector of the mechanism can follow a desired trajectory with wondrous precision under high acceleration. An ultra-precision positioning technique has been developed with the combination of a global stage and micro stage in [2] in order to achieve sub-micrometer accuracy.…”

“…As a first step to create a DT of a robotic mechanism presented in [1], the servo motor system of this mechanism is considered in this work. Two servo motors are used in this planar parallel mechanism.…”
