BALTIMORE, Md. – In looking for creative inspiration, engineering student Qiyuan Fu finds it in a box, with an interesting occupant. Inside: a real, live snake. “We can definitely learn something from them,” Fu said. The snake is a Kingsnake, which is native to deserts in California and Mexico and serves as the model for a new robot, developed in a mechanical engineering lab at Johns Hopkins University. “We added this one directional wheel, so it can only rotate in one direction,” said Fu, as he demonstrated how the robot moves. The “snake robot,” and its colleague, the “roach robot,” are so-called “bio-inspired robots” – taking their cues from mother nature. “We studied snakes here because they are exceptionally good at moving through almost any terrain,” said Johns Hopkins assistant professor Chen Li. Li said it’s an idea with practical applications: the robots could potentially help in search and rescue, by making their way through tight spaces to find people trapped in rubble. “People have actually tried to build snake robots for several decades,” he said. In the past, though, the robots fell short once they left the lab environments, unable to make it through different types of terrain. This time – using specially positioned cameras – they’ve observed how the snakes and roaches move across different surfaces and attempted to mimic what nature already does so well. “What's really unique about our work is that we focus on understanding the physical principles – starting by looking at animals,” Li said. “And then by understanding such principles, we can apply them to the to the robot.” The snakes have 200 vertebrae; the snake robot has 20 segments. It’s progress, these engineers say, with more to go. “There’s still going to be a lot of challenges ahead,” Li said.The engineering lab is now looking into modeling robots based on lizards. That’s because of their ability to leap across surfaces, which could further help robots make their way across uneven terrain. 2008

The Toronto Raptors will be starting the 2020-21 NBA season in Tampa, the team said in a statement Friday.Raptors owner Masai Ujiri released the following statement:“The Raptors worked diligently with public health officials at the local, provincial and federal level to secure a plan that would permit us to play our 2020-21 season on home soil and on our home court at Scotiabank Arena. These conversations were productive, and we found strong support for the protocols we put forward. Ultimately, the current public health situation facing Canadians, combined with the urgent need to determine where we will play means that we will begin our 2020-21 season in Tampa, Florida.We want to thank all levels of government and their public health officials for their dedication to this process, and for looking after the health of Canadians. We commit to continuing our work together, planning for a safe return to play in Toronto. And as an organization, we remain committed to doing all we can to promote and demonstrate public health measures to help combat the spread of COVID-19 in Canada.So we’ll be away from our home and our fans for now. They say absence makes the heart grow fonder. I’m not sure that’s possible for us – we love Toronto and Canada, and we know we have the best fans in the NBA. For now, I’ll ask you to cheer for us from afar, and we’ll look forward to the day we are all together again.”Games will be played at AMALIE Arena, home of the Tampa Bay Lightning.Even Lightning Captain Steven Stamkos was excited about the news:“ WE THE SOUTH” ?? https://t.co/hVHlJKItrh— Steven Stamkos (@RealStamkos91) November 20, 2020 This past MLB season, the Toronto Blue Jays had to make their home in Buffalo due to Canada's COVID-19 restrictions.The NBA season tips off on Dec. 22.

Kyle Rittenhouse's attorney has filed a motion to dismiss two charges late Tuesday.According to court records, they seek to dismiss Possession of a Dangerous Weapon by a Person Under 18, and First Degree Recklessly Endangering Safety, Use of a Dangerous Weapon.Rittenhouse is facing a total of six charges, including two counts of 1st-Degree Reckless Homicide after prosecutors say he shot and killed two people and wounded a third during protests in Kenosha.Attorney Mark Richards argues in Tuesday's filing that possession of a dangerous weapon by a person under 18 should be dismissed because "the complaint [filed against Rittenhouse] fails to allege facts which could allow a reasonable person to conclude that a crime was committed."In regard to first-degree recklessly endangering safety, Richards writes that "no reasonable person could find that this crime was ever committed. Thus, the criminal complaint is defective and Count 2 should be dismissed."

Huber and Joseph Rosenbaum, and wounded Gaige Grosskreutz during protests in Kenosha on Aug. 25.Supporters of the Black Lives Matter movement paint Rittenhouse as a white supremacist and militia member. Rittenhouse and his attorneys argue that he acted in self-defense, an argument that has become a rallying cry for some on the right.If convicted, Rittenhouse could spend life behind bars.This article was written by Jackson Danbeck for WTMJ. 2040

EVANSTON, Ill. – If you drive too fast, you could miss it. But a chance turn into one alley just north of Chicago will transport you into a drive-thru art gallery. “I wanted to take this place this alley which is just ugly or lackluster and make it into something special,” explained Teresa Parod. The Evanston, Illinois-based painter and artist is the person behind several vibrant garage door murals. From floral motifs to interplanetary themes, her goal she says is to uplift people through her painting. “I want all my public art to be positive because no one who walks down this alley… most didn't ask me to paint this,” she said. “So, I don't want them to come and see some something that is very negative or makes them feel unhappy.” The canvases range from one-and-a-half to two car garage doors. She only charges for material. The medium: house paint. “What I really like is when people come who are not in the neighborhood and they're just riding their bikes or walking dog and they're like well what is this? And it's something special,” said Parod. The artist started with her own door, concerned with how her neighbors might respond. “This is my own garage. And I thought it would be fun to put the front of my house on my garage,” she said. But many have embraced transforming the back alley into a gallery of vibrant, public works of art. Neighbor Judy Slagle saw the work and just had to have her garage door painted as well. Hers is a collection of brightly colored sunflowers. “When I came home especially in the winter like it is now, I wanted to come home and have something that would make me smile and other people I hope too,” said Slagle For an enhanced experience, Parod’s husband Bill, a sound artist and software developer, is creating an augmented reality app. Virtual birds can be seen on the screen interacting with the paintings. He is designing customized vignettes for each door. “So that we could walk to them and you could hear something in 3D and walk around and the birds and so on could fly around,” he explained. The doors are now in high demand. “Everybody started asking me to do them and I have a waiting list,” said Parod. “So, I hope to do the whole alley and I hope to do more alleys.” And while Parod may see the world as her canvas, this time it’s right up her alley. 2346
