In this paper, we analyze systems with low throughput human-machine interfaces (such as a brain-computer interface, single switch interface) from the controls perspective. We develop some principles for performance improvement in such systems based on the parallelization of inference and robot motion. The proposed principles are used to design a novel shared position control to navigate a circular massless holonomic robot in a known environment. The system is implemented in simulation and integrated with a real robotic wheelchair. Robot experiments demonstrated the viability of the proposed navigation method in various modes of operation.

A Small-scale Implementation of Industry 4.0
This paper discusses the implementation of Industry 4.0 in an educational setting. Simulation, virtual reality, analytics, robotics and automation, and 3D printing are integrated to develop a small-scale production line for producing and inspecting 3D printed parts. The system consists of a robot and controller, programmable logic controller, 3D printer, machine vision system, conveyor belt, 3-phase motor and motor controller, webcam, PC and monitor, Raspberry Pi computer, pneumatic system, beam sensor, simulation software, and VR equipment. The system components are connected via ethernet cables running to a basic ethernet switch. An ethernet router is also connected to the switch to resolve IP connection attempts by the connected components. A mini CNC machine is used to drill holes on small metal parts that are assembled with 3D printed parts and plastic bricks to make a car toy. A robot is pre-programmed to perform the assembly of the car toy and a Cognex® camera is used to inspect the parts. Deep learning models are used to predict the remaining useful life of the drilling bits.

Today, saying Additive Manufacturing (AM) is changing our world is an understatement. Current applications include additively manufactured shoes, jewelry, prosthetics, and food products. In this study, a steering rack extension for Tennessee Tech’s Formula SAE (FSAE) car was replaced with various 3D printed alternatives. Numerous beta testing studies were performed to measure its sustainability. Utilization of a Steering Rack Extension is made to adapt a quick ratio steering rack to interface with the steering system designed for the TTU Motorsports FSAE car. The current study reports the design, analysis, and manufacturing studies performed to replace the steering rack extension with a 3D printed component. Various tests and 3D printing operations have been performed to show the improvements made to replace the currently used piece. This presentation will report the design, printing and testing studies performed for the newer steering rack extension. Student feedback received from the FSAE team and engineering students will be also presented.more » « less

Robot-mediated interventions are one promising and novel approach for encouraging motor exploration in young children, but knowledge about the effectiveness of toy-like features for child-robot interaction is limited. We were interested in understanding the characteristics of current toys to inform the design of interactive abilities for assistive robots. This work first provides a systematic review of toy characteristics in n=154 Fisher-Price products and then analyzes the effectiveness of common and uncommon toy-like behaviors from our custom assistive robot. Toy review results showed that light and sound features were significantly more common than bubbles, wheels, and self-propulsion. Exploratory play sessions with our assistive robot showed that bubbles were significantly more successful at encouraging child motion than other robot behaviors. Further, all studied robot behaviors demonstrated the capability to encourage child motion. The products of this work can inform the efforts of human-robot interaction and child development experts who study child mobility interventions.more » « less

Zmuidzinas, Jonas ; Gao, Jian-Rong (Ed.)An often unglamorous, yet critical, part of most millimeter/submillimeter astronomical instruments is cryogenic temperature monitoring and control. Depending on the operating wavelength of the instrument and detector technology, this could be stable temperatures in the Kelvin range for millimeter heterodyne systems to 100 mK temperatures at sub-micro-Kelvin stability as for many submillimeter bolometer systems. Here we describe a project of the HARDWARE.astronomy initiative to build a low-cost open-source temperature monitoring and control system. The HARDWARE.astronomy Housekeeping Box, or H.aHk Box (pronounced “hack box”) is developed primarily by undergraduates and employs existing open-source devices (e.g Arduino, Raspberry Pi) to reduce costs while also limiting the complexity of the development. The H.aHk Box features a chassis with a control computer and ten expansion slots that can be filled with a variety of expansion cards. These cards include initially an AC 4-wire temperature monitor and PID control cards. Future work will develop 2-wire temperature monitors, stepper motor controller, and high-power supply. The base-system will also be able to interface with other house-keeping systems over USB, serial port and ethernet. The first deployment of the H.aHk Box will be for the ZEUS-2 submillimeter grating spectrometer. All designs, firmware, software and parts list will be published online allowing for other projects to adopt the system and create custom expansion cards as needed. Here we describe the design (including mechanical, electrical, firmware, and software components) and initial performance of the H.aHk Box system with initial AC/DC 4-wire and PID cards.more » « less

Controlling soft continuum robotic arms is challenging due to their hyper-redundancy and dexterity. In this paper we experimentally demonstrate, for the first time, closed-loop control of the configuration space variables of a soft robotic arm, composed of independently controllable segments, using a Cosserat rod model of the robot and the distributed sensing and actuation capabilities of the segments. Our controller solves the inverse dynamic problem by simulating the Cosserat rod model in MATLAB using a computationally efficient numerical solution scheme, and it applies the computed control output to the actual robot in real time. The position and orientation of the tip of each segment are measured in real time, while the remaining unknown variables that are needed to solve the inverse dynamics are estimated simultaneously in the simulation. We implement the controller on a multi-segment silicone robotic arm with pneumatic actuation, using a motion capture system to measure the segments' positions and orientations. The controller is used to reshape the arm into configurations that are achieved through combinations of bending and extension deformations in 3D space. Although the possible deformations are limited for this robot platform, our study demonstrates the potential for implementing the control approach on a wide range of continuum robots in practice. The resulting tracking performance indicates the effectiveness of the controller and the accuracy of the simulated Cosserat rod model.more » « less
