A Russian robotics company said one of its autonomous Promobots was taken out by a self-driving Tesla on the eve of the Consumer Electronics Show in Las Vegas. Promobot shared a video recorded outside of the Westgate Las Vegas Resort & Casino showing one of its namesake machines at the side of a driveway at the facility. Multiple cars easily pass by the autonomous robot, but a self-driving Tesla Model S collides with the robot and drives away. The Promobot, which is knocked off its wheels, was destroyed, the company said. The collision took place about half a mile from CES, the technology trade show that began Tuesday.
