The performance of algorithms for pose estimation hinges on the robot's sensors being able to detect discriminative geometric object features, but previous sensing modalities are unable to make such measurements robustly. It’s neat to see it coming back.During in-hand manipulation, robots must be able to continuously estimate the pose of the object in order to generate appropriate control actions. “It’s so weird to walk around the school and see all these kids carrying cubes. New cubes connect to Bluetooth so you can go through the movements with the students – as they turn them, it turns on the screen. “Those ones from the ’80s are so hard to turn, it’s like there’s sand in them. “My mother passed away the first year I moved up here, and I have her Rubik’s Cube – it has the wrong colours, it has pink on one side – in the glove compartment of my Jeep,” he said. Seeing young Yellowknifers embrace an ’80s icon warms Richardson’s heart. Owen is now planning his own cubing club, “not only to teach new cubers but also as a space for people to hang out and solve cubes together.” The kids don’t have that block right away, they just look at the sheet and keep practising.” It’s no different than learning any other skill. But the beginner method is very, very basic. “With the cube, a lot of adults think they can either solve it or they can’t. “A lot of the patterns in games like Fortnite, The Witcher, and Zelda are so much more complicated than pressing a few buttons down on a trumpet. “I compare it to music and learning guitar solos,” he said, grouping the cube in with video games as hobbies that require transferable skills. Richardson, as a music teacher, draws parallels between the cube and learning an instrument in explaining how being a cuber can help students. He then has 15 seconds, on camera, to lift the cover and inspect the cube before beginning. Tournament organizers send instructions to scramble the cube, which Owen does before placing it under a cover. Owen awaits his first opportunity to compete in person once the pandemic recedes. I just wanted to get faster and faster to the point where nobody could beat me.” Owen said: “Getting good, to me, was like: I could beat my music teacher some day. You’re in Grade 7, Grade 8, you don’t have families, this is the time to go after this hobby,” said Richardson. “I told Owen and a few others: You guys have the time. I would come into any class and there would be 10 of them on my desk to solve.”Īt least one other student had already travelled to a cubing competition in Vancouver – only to see it cancelled by the onset of Covid-19 – by the time Owen’s interest grew. “I would always have the cube in my hand walking around the halls and it developed into this kind-of ’80s culture of cubing at school. ![]() I wrote down all the algorithms on a sheet and practised them at recess. It would be sitting on a shelf, solved, and she never told me how she did it,” Richardson said, describing how he embraced the cube as an adult. “Growing up during the ’80s and ’90s, my mother was the only person I knew who could solve the cube. Stephen Richardson, an École St Joseph School music teacher, described algorithms as the patterns you must follow to solve any scrambled, or unsolved, cube. “He almost always has a cube in his hands and spends hours every day learning algorithms and practising his skills, always trying to beat his own records,” Winsor said last week.
