Mina Konaković Luković and Yunsheng Tian’s paper Diversity-Guided Multi-Objective Bayesian Optimization With Batch Evaluations has been accepted to NeurIPS 2020. In this paper, we propose a novel multi-objective Bayesian optimization algorithm called DGEMO that is used to automate the process of discovering the Pareto-optimal solutions for multi-objective problems, while minimizing the number of performed evaluations. Our algorithm predominantly outperforms relevant state-of-the-art methods on all the benchmark problems.
Andrew Spielberg’s paper A Simple, Inexpensive, Wearable Glove with Hybrid Resistive‐Pressure Sensors for Computational Sensing, Proprioception, and Task Identification has been published in Advanced Intelligent Systems. In this paper, Andy and his collaborators from Professor Daniela Rus’ lab presented a fully soft, wearable glove which is capable of real‐time hand pose reconstruction, environment sensing, and task classification. The design is easy to fabricate using low cost, commercial off‐the‐shelf items in a manner that is amenable to automated manufacturing. The system can reconstruct user hand pose and identify sensory inputs such as holding force, object temperature, conductability, material stiffness, and user heart rate, all with high accuracy.

Two papers on the application of multi-objective optimization techniques in supervised learning and reinforcement learning have been accepted to ICML 2020: Prediction-Guided Multi-Objective Reinforcement Learning for Continuous Robot Control from Jie Xu, Yunsheng Tian, and Pingchuan Ma proposed an efficient evolutionary learning algorithm to find the Pareto set approximation for continuous robot control problems, and Efficient Continuous Pareto Exploration in Multi-Task Learning from Pingchuan Ma and Tao Du presented a novel, efficient method that generates locally continuous Pareto sets and Pareto fronts for multi-task learning problems. Details about the two papers will be available soon.
The paper Physical Realization Of Elastic Cloaking With A Polar Material was recently accepted to Physical Review Letters (PRL). In this paper, Wan Shou and Beichen Li collaborated with researchers at University of Missouri and Dalian University of Technology to propose a novel elastic cloak by designing and fabricating a new class of polar materials with a distribution of body torque that exhibits asymmetric stresses. The work sets a precedent in the field of transformation elasticity and should find applications in mechanical stress shielding and stealth technologies.

Our proposed 3D gaze model extends existing models to include temporal information and to directly output an estimate of gaze uncertainty. Finally, we demonstrate an application of our model for estimating customer attention in a supermarket setting. This paper was was in collaboration with Professor Antonio Torralba’s group and Toyota Research Institute.

In our latest work published in Science Advances, our group presented an automated system that designs and 3-D prints complex robotic actuators which are optimized according to an enormous number of specifications. We demonstrate the system by fabricating actuators that show different black-and-white images at different angles. One of our actuators portrays a Vincent van Gogh portrait when laid flat and the famous Edvard Munch painting “The Scream” when tiled an angle. We also 3-D printed floating water lilies with petals equipped with arrays of actuators and hinges that fold up in response to magnetic fields run through conductive fluids.
Our latest work on human grasping “Learning the signatures of the human grasp using a scalable tactile glove” was published in Nature. In this paper, we use a scalable tactile glove and deep convolutional neural networks to show that sensors uniformly distributed over the hand can be used to identify individual objects, estimate their weight and explore the typical tactile patterns that emerge while grasping objects. Using a low-cost (about US$10) scalable tactile glove sensor array, we record a large-scale tactile dataset with 135,000 frames, each covering the full hand while interacting with 26 different objects. This set of interactions with different objects reveals the key correspondences between different regions of a human hand while it is manipulating objects. Insights from the tactile signatures of the human grasp—through the lens of an artificial analog of the natural mechanoreceptor network—can thus aid the future design of prosthetics, robot grasping tools, and human-robot interactions.
Our PhD student Jie Xu will present his latest work “Learning to Fly: Computational Controller Design for Hybrid UAVs with Reinforcement Learning” at SIGGRAPH 2019 this summer.

Cables provide a natural, biomimetic means of actuating robots, but figuring out how to route them to get the motion you want can be unintuitive. Our methods automate this process, and make it easy to design puppets, animatronics, and robots, for novices and experts alike. See the full paper at SCA ‘17.
Tired of spending time meant for your mechanical design work actually just waiting for simulations to finish?
Last Sunday our PhD student Andrew Spielberg presented a talk on “Co-Optimization of Robots and Mechanisms” at this year’s RSS workshop on minimality (minimality.mit.edu). In this talk, Andy presented recent work (ICRA ‘17) on the co-optimization of whole-body robot trajectories and design parameters from high-level task specifications. Their method requires minimal user domain knowledge, requiring only a coarse guess of the target robot configuration sequence and a parameterized robot topology as input. Further, this method considers the physical constraints afforded by the actuators, and selects the minimal actuators possible for task feasibility. Following this work, he also presented methods for improving the fabricability of such mechanisms using cable-driven actuation (SCA ‘17). Andy then presented work (IJRR ‘17) which makes this otherwise mathematically-intensive design process more intuitive for human users by presenting more intuitive, end-to-end CAD-like robot design software. Finally, Andy discussed some of the most important open problems facing the automated robot design community moving forward.
