Combining Haptics with an Omnidirectional Mobile Robot

Videos

This video introduces and demonstrates a new system that expands the usable workspace of a haptic device in an immersive environment by attaching it to a mobile robot with a Mecanum-style drive.

Research was performed by Ryan A. Pavlik, Dr. Judy M. Vance and Dr. Greg R. Luecke at Iowa State University’s Virtual Reality Applications Center.

As the user manipulates the end effector of the haptic device, the mobile robot moves the haptic device base to follow the user through the space. This in effect expands the usable workspace of the haptic device from the reachable volume of the device to the entire position tracked area in an immersive environment. When contact is made with virtual objects, the device applies a highly accurate and realistic penalty-based haptic force that is grounded through the mobile robot base.

Ryan Pavlik is pictured operating the haptic device. More information on this project is available at https://ift.tt/2npw0Tt project “Haptics for Large Space Virtual Environments to Assess Assembly Tasks”)

The three-wall CAVE immersive environment shown here is known as “METaL”:

The haptic device is a Haption Virtuose 6D35-45, on a custom built mount. The mobile robot is based on the “4WD Mecanum Wheel Robot Kit”, Nexus Robot model 10011, with a custom software stack on its embedded microcontroller.

SPARTA, the “Scriptable Platform for Advanced Research and Teaching in Assembly”, is the software that powers the virtual environment and the haptic interaction with CAD models.

TYT To Host Climate Debate After DNC Bails. TYT.com/townhall

Uncategorized, Videos

The DNC voted to not allow the Democratic candidates to participate in a climate change debate. Make a Climate Town Hall happen: https://ift.tt/2ZuxSMf

“San Francisco (CNN)Democratic National Committee members on Saturday voted down a resolution that would have resulted in single-issue debates among candidates — including on the issue of the climate crisis.

The language that was rejected — inserted at the behest of climate change activists during a contentious Resolutions Committee meeting on Thursday — said the DNC, “will continue to encourage candidates to participate in multi-candidate issue-specific forums with the candidates appearing on the same stage, engaging one another in discussion.”
Democratic presidential candidates are barred from appearing together on stage outside of DNC-sanctioned debates.

The committee’s approved language from Thursday “essentially lifted the ban on candidates being unable to appear together on a stage at a forum or a candidate gathering,” Washington State Democratic Party Chair Tina Podlodowski, a leader in the effort, told CNN. DNC members defeated the move to lift such a ban Saturday in a 222-137 vote. There were multiple observers from both sides who monitored the vote count.

Prior to the voting, DNC Chairman Tom Perez set up a system for members on both sides to speak about their reasoning.”

Obsessed: Guy Has Eaten At Over 7,000 Chinese Restaurants

Uncategorized, Videos

David R. Chan isn’t your typical Chinese food enthusiast. He can’t speak Chinese, he doesn’t use chopsticks, and he grew up barely eating anything Chinese. But the Los Angeles native has over his adult life, obsessively eaten at over 7,000 Chinese restaurants, mostly in America, and has them all methodically logged in an Excel spreadsheet. This is his story.
