Patent number: 8662213Abstract: An amorphous robot includes a compartmented bladder containing fluid, a valve assembly, and an outer layer encapsulating the bladder and valve assembly. The valve assembly draws fluid from a compartment(s) and discharges the drawn fluid into a designated compartment to displace the designated compartment with respect to the surface. Another embodiment includes elements each having a variable property, an outer layer that encapsulates the elements, and a control unit. The control unit energizes a designated element to change its variable property, thereby moving the designated element. The elements may be electromagnetic spheres with a variable polarity or shape memory polymers with changing shape and/or size. Yet another embodiment includes an elongated flexible tube filled with ferrofluid, a moveable electromagnet, an actuator, and a control unit. The control unit energizes the electromagnet and moves the electromagnet via the actuator to magnetize the ferrofluid and lengthen the flexible tube.Type: GrantFiled: January 3, 2012Date of Patent: March 4, 2014Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Arthur T.

Patent number: 8657042Abstract: A steerable walking machine is described which comprises a leg mechanism that provides a means for locomotion of the machine across a surface and a head rotatably mounted upon the leg mechanism. The rotational position of the head upon the leg mechanism acts to defines a direction of locomotion of the machine across the surface. The steerable walking machine can therefore walk in any direction without requiring the leg mechanism to turn and so can maneuver in more confined spaces than those devices known in the art. A first motor is employed to control the leg mechanism while a second motor controls the rotation of the head upon the leg mechanism. The functionality of the steerable walking machine is therefore achieved through the employment of only two motors thus significantly reducing the manufacturing costs involved.Type: GrantFiled: October 4, 2010Date of Patent: February 25, 2014Assignee: China Industries LimitedInventor: Jaimie Hartwig Barrett Mantzel

Patent number: 8651206Abstract: Devices, systems, and methods for inspecting and objectively analyzing the condition of a roof are presented. A vehicle adapted for traversing and inspecting an irregular terrain includes a chassis having a bottom surface that defines a higher ground clearance at an intermediate location, thereby keeping the center of mass low when crossing roof peaks. In another embodiment, the drive tracks include a partially collapsible treads made of resilient foam. A system for inspecting a roof includes a lift system and a remote computer for analyzing data. Vehicles and systems may gather and analyze data, and generate revenue by providing data, analysis, and reports for a fee to interested parties.Type: GrantFiled: March 31, 2012Date of Patent: February 18, 2014Assignee: Tobor Technology, LLCInventors: Michael D. Slawinski, Dennis L. Guthrie

Patent number: 8622158Abstract: A transport apparatus for use in modular construction, specifically a dual-deck hydraulic apparatus that, while carrying a payload, can detect topology changes and adjust accordingly to keep the payload in substantially the same position. The apparatus can efficiently transport modular building components while preventing torsion and other damage. The apparatus can also adapt to off-load modules to foundations or multi-story heights.Type: GrantFiled: April 26, 2010Date of Patent: January 7, 2014Inventor: Michael Leonard

Patent number: 8579056Abstract: A transport device includes a support base, at least two spiral drives, at least one drive device, a control device and a power source. Each one of the at least two spiral drives are preferably driven by a single drive device. However, a single drive device could drive the at least two spiral drives through some type of drive system. The at least two spiral drives are rotatably retained on the support base. The at least two spiral drives are rotated through any suitable drive system. The power source supplies power to the at least one drive device through the control device. The control device controls the rotation and the amount of power sent to the at least one drive device. An object to be transported is placed on the support base. However, multiple transport devices may be attached to multiple sides of the object.Type: GrantFiled: March 14, 2013Date of Patent: November 12, 2013Inventor: Lowell C. Frank

Publication number: 20130274973Abstract: A wheeled vehicle comprising a power-driven spider assembly for ascending and descending stairs. The vehicle includes an angular position sensor providing input to a controller operable to control a servo-motor to effectively lock the position of the spider relative to the frame, regardless of the hand truck's spatial orientation relative to a vertical plane, or any balancing of the hand truck. The angular position sensor provides input to the controller, which is programmed with predefined angular zones of instability, and causes the controller to accelerate rotation of the spiders through those zones when the wheeled vehicle is in the descent mode, to avoid instability of the hand truck. A hand truck may include a removable basket and/or a pivotable platform usable to transport loads.Type: ApplicationFiled: April 12, 2013Publication date: October 17, 2013Inventors: Steven Kamara, Michael Yang, Joseph Sarokhan
