In the face of challenges encountered during femur fracture surgery, such as the high rates of malalignment and X-ray exposure to operating personnel, robot-assisted surgery has emerged as an alternative to conventional state-of-the-art surgical methods. This paper introduces the development of Robossis, a haptic system for robot-assisted femur fracture surgery. Robossis comprises a 7-DOF haptic controller and a 6-DOF surgical robot. A unilateral control architecture is developed to address the kinematic mismatch and the motion transfer between the haptic controller and the Robossis surgical robot. A real-time motion control pipeline is designed to address the motion transfer and evaluated through experimental testing. The analysis illustrates that the Robossis surgical robot can adhere to the desired trajectory from the haptic controller with an average translational error of 0.32 mm and a rotational error of 0.07 deg. Additionally, a haptic rendering pipeline is developed to resolve the kinematic mismatch by constraining the haptic controller (user hand) movement within the permissible joint limits of the Robossis surgical robot. Lastly, in a cadaveric lab test, the Robossis system assisted surgeons during a mock femur fracture surgery. The result shows that Robossis can provide an intuitive solution for surgeons to perform femur fracture surgery.

Chiquita Evans became the first woman ever drafted into the video game NBA 2K League when she was selected in the fourth round Tuesday night by Warriors Gaming, which is run by the Golden State Warriors. Evans is now the esports league's first female pro. Each of the 126 players in the league will make between $33,000 and $37,000 per season, plus benefits and team housing. "It feels surreal,'' she said. Evans, who lives in Mobile, Ala., was one of two women who qualified for the draft this year through the league's online combine. The other, Brianna Novin, was not selected. The NBA and game publisher Take-Two Interactive run the league. The league had no women in its first season, and the NBA wanted to change that. They hired some analysts to talk to focus groups to determine why only men qualified for the league. "It made us put more emphasis on how good a player was when they got the ball in their hands,'' 2K League managing director Brendan Donohue said.

Lonnie Johnson was brought up in Mobile Alabama in the 1960s, when black children were not expected to go far, but such was his talent for engineering that he worked for Nasa, and helped test the first stealth bomber. But as he explains here, the invention that made his fortune was a water pistol - the extremely powerful Super Soaker. It started with my dad. He gave me my first lesson in electricity, explaining that it takes two wires for electric current to flow - one for the electrons to go in, the other for them to come out. And he showed me how to repair irons and lamps and things like that. The kids in the neighbourhood took to calling me "the Professor".
