Miniature Robotic Vehicles And Methods Of Controlling Same

View page
US Patent:
6548982, Apr 15, 2003
Filed:
Nov 17, 2000
Appl. No.:
09/715959
Inventors:
Nikolaos P. Papanikolopoulos - Minneapolis MN
Donald G. Krantz - Eden Prairie MN
Richard M. Voyles - North Oaks MN
John A. Bushey - Eden Prairie MN
Alan N. Johnson - Chanhassen MN
Bradley J. Nelson - North Oaks MN
Paul E. Rybski - Minneapolis MN
Kathleen A. Griggs - Damascus MD
Assignee:
Regents of the University of Minnesota - Minneapolis MN
International Classification:
B25J 918
US Classification:
31856811, 31856812, 901 50, 446435, 446470, 446457
Abstract:
A robotic vehicle capable of traveling over various terrain and traversing obstacles. In one embodiment, the vehicle includes a cylindrical body having two or more drive wheels coupled to the ends thereof. The wheels are selectively powered to propel the vehicle. The vehicle may further include a spring member which may be deflected to a first, stored position from a second, extended position. The spring member may be quickly released from the first, stored position such that it strikes the terrain with sufficient force to lift and propel the vehicle over or onto a proximate obstacle or object. Robotic vehicles of the present invention may also include one or more sensing devices operable to collect information. Electronics may further permit autonomous, semi-autonomous, and/or remote control of the vehicle. In still other embodiments, the robotic vehicle forms part of a multi-robot surveillance team.

Computer Assisted Determination Of Tapped Threads From Cad File

View page
US Patent:
8295971, Oct 23, 2012
Filed:
Sep 2, 2009
Appl. No.:
12/553088
Inventors:
Donald G. Krantz - Eden Prairie MN, US
Assignee:
Proto Labs, Inc. - Maple Plain MN
International Classification:
G06F 19/00
US Classification:
700182, 700 98, 700197, 345419, 345420, 703 2
Abstract:
A computer program, system and method receives a customer's CAD file of a custom part to be formed. Depending upon customer responses to several basic queries, the CAD file is analyzed to identify acceptable holes for tapping. For each identified hole, an appropriate and available thread size is automatically selected, even if the cylindrical recess differs in size from the characteristic size of the threaded hole. The customer is then automatically advised 10 of the results of the tapping analysis, preferably as part of a quotation for part manufacture that identifies the number of threaded holes in the part and preferably identifies the changes to the tapped holes and the specific thread form being quoted for the hole.

Miniature Robotic Vehicles And Methods Of Controlling Same

View page
US Patent:
20030137268, Jul 24, 2003
Filed:
Dec 10, 2002
Appl. No.:
10/315341
Inventors:
Nikolaos Papanikolopoulos - Minneapolis MN, US
Donald Krantz - Eden Prairie MN, US
Richard Voyles - North Oaks MN, US
Assignee:
Regents of the University of Minnesota - Minneapolis MN
International Classification:
B25J009/18
US Classification:
318/568110
Abstract:
A robotic vehicle having a body with two or more powered ground-engaging members, e.g., wheels, rotatably coupled thereto. The vehicle may further include a spring member which may be deflected to a first, stored position from a second, extended position. The robotic vehicle may form part of a distributed, multi-robot system. The robotic vehicles may communicate with each other and/or a remote workstation. In some embodiments, the robotic vehicles may mechanically couple to one another to perform certain tasks.

System For Transmitting Multiple Signals Across A Single Fiber Optic Channel

View page
US Patent:
54265274, Jun 20, 1995
Filed:
Jun 3, 1994
Appl. No.:
8/253628
Inventors:
Roger D. Steen - Apple Valley MN
Donald G. Krantz - Eden Prairie MN
Assignee:
Alliant Techsystems Inc. - Hopkins MN
International Classification:
H04J 1408
H04J 1400
US Classification:
359123
Abstract:
The present invention is a system for the transmission of a plurality of analog video, analog audio, and discrete signals across a single fiber optic cable. The system includes a transmitter which first digitizes the analog video and audio signals and then converts a combination of the digital video, digital audio, and discrete signals into a single serial digital data stream. The system modulates this digital data stream into a corresponding lightwave signal and transmits the lightwave signal across the fiber optic cable. A receiver within the system demodulates the lightwave signal into a serial digital data stream, which is then converted into a parallel signal so that the receiver may restore the analog video, analog audio, and discrete signals from the parallel combination of signals.

Active Cross Path Position Correlation Device

View page
US Patent:
53315618, Jul 19, 1994
Filed:
Apr 23, 1992
Appl. No.:
7/872497
Inventors:
William A. Barrett - Shorewood MN
Donald G. Krantz - Eden Prairie MN
Assignee:
Alliant Techsystems Inc. - Hopkins MN
International Classification:
G06G 764
G08G 116
US Classification:
364447
Abstract:
A system guides a vehicle along a predefined path by correlating vehicle side range profiles. A lead vehicle gathers side range data using active radiation sources such as light emitting diodes. A microprocessor-based system on board the lead vehicle stores the data into records of a database file, tagging each record to indicate a relative position along the path when the lead vehicle obtained the data. A system on board a follower vehicle gathers its own side range data and also generates a side range profile for the follower vehicle. The follower vehicle's system receives by radio communication the side range profiles from the lead vehicle and, using the tagging information, correlates these profiles with the follower vehicle side range profiles at appropriate points along the path. As a result of the correlation, the follower vehicle's system outputs commands to actuators coupled to the vehicle's steering system, throttle, and braking system to control the vehicle's motion so that the vehicle traverses the predefined path.
