Patent number: 10196104Abstract: An example method includes determining a plurality of candidate support regions for a support member of a robotic device. The method also includes determining a support region score (SRS) for each candidate support region, wherein the SRS for a given candidate support region depends on a surface geometry of the given candidate support region. The method additionally includes determining an adjacent relation scores (ARS) for each candidate support region, wherein the ARS for a particular candidate support region is based at least on a plurality of SRSs of a plurality of support regions surrounding the particular candidate support region. Based on the determined SRSs and the determined ARSs, the method further includes selecting at least one support region from the plurality of candidate support regions and providing instructions for the robotic device to place the support member on the at least one selected support region.Type: GrantFiled: November 27, 2016Date of Patent: February 5, 2019Assignee: Schaft Inc.Inventors: Satoshi Kagami, Koichi Nishiwaki

Patent number: 9950430Abstract: A robotic system may include an incremental encoder coupled to a joint of the system. The robotic system may include a memory configured to store representations of angular positions of the joint. The robotic system may include a motor coupled to the joint, where rotation of the joint while the motor is powered off (i) causes rotation of the motor such that electric power is generated, and (ii) updates the angular position of the joint. The robotic system may use the electric power to power on the incremental encoder and the memory while the robotic system is powered off. One or more processors may obtain, when the robotic system powers on after being powered off, the updated angular position of the joint from the memory, where the incremental encoder provides the updated angular position to the memory while the robotic system is powered off.Type: GrantFiled: December 6, 2016Date of Patent: April 24, 2018Assignee: Schaft Inc.Inventors: Nobuyuki Ito, Junichi Urata, Koichi Nishiwaki

Patent number: 7044576Abstract: The machine adjustment device of the invention displays a list of components constituting a printer in a sequential manner and asks the user to select one or multiple components to be removed or replaced. The machine adjustment device extracts adjustment parameters, which require adjustment accompanied with removal or replacement of the one or multiple selected components, and sets an adjustment order of the extracted adjustment parameters. The machine adjustment device outputs display of an adjustment window including the extracted adjustment parameters in the preset adjustment order and interactively executes adjustment of the printer with operations of the user. This arrangement enables even an unskilled user to implement easy, quick, and adequate adjustment required in the case of removal or replacement of the components in the printer.Type: GrantFiled: October 31, 2003Date of Patent: May 16, 2006Assignee: Seiko Epson CorporationInventors: Yoshiharu Kune, Koichi Nishiwaki, Takahiro Minamoto
