Audi introduced its concept car Audi AI: Trail at the IAA 2019. The car is special because it combines futuristic design with autonomous driving, electric mobility.
MIT’s new mini cheetah robot is a four-legged robot that can bend and swing with legs enabling to walk either right-side up or upside down. The robot can also trot over uneven terrain about twice as fast as an average person’s walking speed.
“You could put these parts together, almost like Legos,” says lead developer Benjamin Katz, a technical associate in MIT’s Department of Mechanical Engineering.
“A big part of why we built this robot is that it makes it so easy to experiment and just try crazy things, because the robot is super robust and doesn’t break easily, and if it does break, it’s easy and not very expensive to fix,” says Katz, who worked on the robot in the lab of Sangbae Kim, associate professor of mechanical engineering.
The cheetah robot will be presented at the International Conference on Robotics and Automation, in May. The researchers currently are developing more of the four-legged machines, aiming for a set of 10, each of which they hope to loan out to other labs.
“Eventually, I’m hoping we could have a robotic dog race through an obstacle course, where each team controls a mini cheetah with different algorithms, and we can see which strategy is more effective,” Kim says. “That’s how you accelerate research.”
“In Cheetah 3, everything is super integrated, so if you want to change something, you have to do a ton of redesign,” Katz says. “Whereas with the mini cheetah, if you wanted to add another arm, you could just add three or four more of these modular motors.”
