The model T is an open-source, low-cost, robotic hand that can be created through rapid-prototyping techniques and off-the-shelf components.
The hand has four fingers with compliant flexure joints and is driven by a single actuator through a pulley tree differential. During grasp acquisition, each finger will continue to move until the links make contact with the object, reducing the need for sensors or feedback control.
To make sure the hand is compatible with 3D printing technologies, the finger designs are converted to structures that have a minimal number of small features and parts.
Overview of the characteristics of underactuated, compliant hands used in this design. Details of the design considerations to meet the requirements of open-source and 3D printing. Describes the build process for a prototype of the hand; in particular, the SDM process used to create in-molded elasto
Provides a brief overview of the biomechanics of the human hand, followed by an in-depth review of kinematic models presented in the literature. Kinematic models for different joints are discussed, along with the explicit and implicit assumptions commonly used in applying the models. General applica
