  • From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

    Creator:
    Hubicki, Christian M.
    Abstract:
    Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...

  • ATRIAS 1.0 & 2.1 : enabling agile biped locomotion with a template-driven approach to robot design

    Creator:
    Grimes, Jesse A.
    Abstract:
    Practical bipedal robots need to be simultaneously efficient, robust, and versatile machines, but designing robots dynamically capable of these demands has been a significant bottleneck. We designed ATRIAS to be a highly dynamic biped capable of both walking and running untethered in real environments. To meet these goals, ATRIAS is...

  • Control of spring-mass running robots

    Creator:
    Vejdani Noghreiyan, Hamid Reza
    Abstract:
    We seek the control strategies that are applicable on legged robots and control them to run in real world as robust and efficient as animals. To achieve this goal, we need to understand the principles of legged locomotion and the control policies that animals use during running. In this study...

  • Dynamics and control for spring-mass legged robots

    Creator:
    Vejdani Noghreiyan, Hamid Reza
    Abstract:
    The objective of this study is to propose control strategies for legged robots to walk and run naturally like humans and animals. To achieve this goal, we use the spring-mass model for the legged robots to be able to create the same dynamics in the leg as humans and animals....

  • Force and impulse control for spring-mass running

    Creator:
    Koepl, Devin N.
    Abstract:
    We present a novel control strategy for running which is robust to disturbances, and makes excellent use of passive dynamics for energy economy. The motivation for our control strategy is based on observations of animals, which are able to economically walk and run over varying terrain and ground dynamics. It...

  • Template-based control of the bipedal robot ATRIAS

    Creator:
    Peekema, Andrew T.
    Abstract:
    This thesis details the derivation and application of template-based controls on a bipedal robot, as well as a description of the software framework that enabled experimentation. The software framework uses a combination of open-source tools including ROS, OROCOS, EtherCAT, and Xenomai to create a real-time environment for the controllers. The...

  • Optimal control of an underactuated bipedal robot

    Creator:
    Jones, Mikhail S.
    Abstract:
    Bipedal robots represent a unique class of control problems that combine many of the most difficult elements of nonlinear control. These robots are typically designed to be mobile and as such have limited energy and actuator authority making efficiency a prime concern. Unlike wheeled robots, legged robots must transition between...

  • Mechanical Design for Robot Locomotion

    Creator:
    Abate, Andrew M.
    Abstract:
    Robotic limbs have been shown to enable mobility in unstructured, real-world terrain; they allow robots to step around cluttered environments, scramble up hills, carry heavy loads, and even perform acrobatics. However, mechanical limbs cannot operate as a means for such dynamic locomotion if they are simply treated as general articulated...

  • Passive dynamics and their influence on performance of physical interaction tasks

    Creator:
    Kemper, Kevin C., II
    Abstract:
    For robotic manipulation tasks in uncertain environments, research typically revolves around developing the best possible software control strategy. However, the passive dynamics of the mechanical system, including inertia, stiffness, damping and torque limits, often impose performance limitations that cannot be overcome with software control. Discussions about the passive dynamics are...

    Creator:
    Luc, Jonathan H.
    Abstract:
    This thesis describes a method for automatically generating and evaluating small-scale off-grid energy systems. Such systems are comprised of components such as solar panels, residential-scale wind turbines, batteries, inverters and charge controllers. These disparate components are assembled into feasible networks through the use of topological optimization and graph grammar rules....
