Open Arms: Open-Source Arms, Hands & Control
Open Arms is a novel open-source platform of realistic human-like robotic
hands and arms hardware with 28 Degree-of-Freedom (DoF), designed to extend the
capabilities and accessibility of humanoid robotic grasping and manipulation.
The Open Arms framework includes an open SDK and development environment,
simulation tools, and application development tools to build and operate Open
Arms. This paper describes these hands controls, sensing, mechanisms, aesthetic
design, and manufacturing and their real-world applications with a teleoperated
nursing robot. From 2015 to 2022, the authors have designed and established the
manufacturing of Open Arms as a low-cost, high functionality robotic arms
hardware and software framework to serve both humanoid robot applications and
the urgent demand for low-cost prosthetics, as part of the Hanson Robotics
Sophia Robot platform. Using the techniques of consumer product manufacturing,
we set out to define modular, low-cost techniques for approximating the
dexterity and sensitivity of human hands. To demonstrate the dexterity and
control of our hands, we present a Generative Grasping Residual CNN (GGR-CNN)
model that can generate robust antipodal grasps from input images of various
objects in real-time speeds (22ms). We achieved state-of-the-art accuracy of
92.4% using our model architecture on a standard Cornell Grasping Dataset,
which contains a diverse set of household objects.Comment: Submitted to 36th Conference on Neural Information Processing Systems
