MEAM Ph.D. Thesis Defense: “Multi-Robot Coordination and Cooperation via Graph-Based Computation”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

Multi-robot coordination and cooperation are critical behaviors that improve team performance and enable new tasks in application areas like autonomous construction, agriculture, and extended operation in large unknown regions. This dissertation examines these behaviors in the context of the multi-robot resource allocation problem, where robots must be allocated to regions of demand. In particular, we […]

MEAM MSE Thesis Defense: “Algorithmic Design of an Origami Squirrel-Inspired Paw for Quadrupedal Locomotion in Bar-like Terrains”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

The Dynamic Origami Quadruped (DOQ), an origami quadrupedal robot, has been primarily utilized for hopping and walking on flat ground. However, adapting it walking on bar-like terrains presents significant challenges. Inspired by the Squirrel-inspired Rapid Tenodesis (SQRT) foot which is capable of passively grasping onto curved surfaces during perching, this thesis explores the integration of […]

MEAM Seminar: “Dynamic Bipedal Walking on Unstructured Terrain through Real-Time Perception and Control”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Bipedal robots have seen significant interest from academia and industry for their potential to efficiently traverse unstructured environments, such as disaster zones, industrial infrastructure, and cluttered homes. Autonomous bipedal walking in the wild remains an unsolved challenge, however, partially due to the difficulty of perceiving and reacting to obstacles in real-time, while maintaining balance. Existing […]

MEAM Seminar: “Soft Pneumatic Force Application through Membrane Design and Stiffness Control”

Towne 337

Modern robotic platforms are designed for precision, but their cost and rigidity make them impractical for many at-home physical human-robot interaction (pHRI) applications. Soft pneumatic actuators (SPA) have potential as safe and affordable means of providing comfortable force application for use in pHRI, but lack shape planning and control during contact. In this seminar, we […]

MEAM Seminar: “Towards Understanding Tactile Sensing Across the Robot Manipulation Stack”

Towne 337

Humans are exceptionally skilled at manipulating a diverse range of objects, apparent from the order of magnitude difference in sizes, weight distributions, stiffnesses, and geometries of items we use on a daily basis. For robots to seamlessly integrate into a world centered around human dexterity, they must also possess comparable manipulation abilities. My research aims […]

MEAM Ph.D. Thesis Defense: “Controlling Contact Transitions for Dynamic Robots”

Towne 311 220 S. 33rd Street, Philadelphia, United States

Legged robots, robotic manipulators, and their combined embodiment as humanoid robots have received considerable attention across both academia and industry. However, with few notable exceptions, state-of-the-art demonstrations are significantly less dynamic than their biological counterparts. A considerable challenge towards achieving more dynamic robots lies within controlling contact interactions with their environment. Legged robots undergoing impacts […]

MEAM Ph.D. Thesis Defense: “Semantics-Driven Active Perception and Navigation with Aerial Robots”

Room 313, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Autonomous aerial robots today are capable of safely navigating through cluttered, GPS-denied environments while constructing an accurate map that captures geometric features such as points, lines, and planes. Such maps are crucial for low-level planning and obstacle avoidance. However, beyond offering details on the density, layout, and dimensions of the environment, these maps provide limited […]

IDEAS Seminar: “Equivariant Neural Inertial Odometry”

Room 401B, 3401 Walnut 3401 Walnut Street, Philadelphia, PA, United States

Abstract:  In this talk, we introduce a new class of problems related to integrating inertial measurements obtained from an IMU that play a significant role in navigation combined with visual data. While there have been tremendous technological advances in the precision of instrumentation, integrating acceleration and angular velocity still suffers from drift in the displacement […]

MEAM Ph.D. Thesis Defense: “Exploring Multimodal Sensing Across the Stack for Robot Manipulation”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Despite substantial progress in robotics, achieving human-like manipulation remains a significant challenge. Existing robotic systems typically leverage human-inspired sensory modalities: vision, touch, and proprioception. However, these modalities are historically studied and integrated in isolation, leading to limited performance in complex real-world tasks that require sensing across multiple modalities for robust generalization. As a result, robots […]

MEAM Seminar: “Differentiable Algorithms for Non-differentiable Robotics: Dexterous Manipulation via Implicit Learning and Control”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

As we ask our robotic systems to become more capable, with the ultimate aim of deploying robots into complex and ever-changing scenarios, the vast space of potential tasks drives the need for flexibility and generalization. For all the promise of big-data machine learning, what will happen when robots deploy to our homes and workplaces and […]
