Or did it? The story seemed too good to be true, and touched a nerve over fears that autonomous vehicles could be dangerous (see the case of Uber’s Arizonan test car that got into a fatal crash last March). In the video, a Tesla Model S can be seen cruising by a robot standing curbside, at which point the Promobot falls over and its arm falls off. Promobot’s manufacturer, also called Promobot, posted footage of the incident to Twitter, tagged Elon Musk, and “Promobot was killed by a self-driving Tesla car” racked up over a million views. Promobot claims that its robot was damaged beyond repair and that they would be filing a police report. How did the robot manage to “run off” to the far side of the road without anyone noticing? How did Promobot seem to know that the Tesla was in self-driving mode? Why was the scene being filmed in the first place? The company has thus far been unable to provide answers, but tech writers and Twitter users were quick to point out the inconsistencies in Promobot’s story.
Look @elonmusk at a Tesla Model S hitting and killing a guiltless robot in Vegas. Your car was under a full self-driving mode. @bheater, @jjvincent, @ingridlunden, @andyjayhawk Check this out!https://t.co/0q605Fdknb— promobot (@promobot) January 7, 2019
Tesla’s cars, while equipped with an “Autopilot” mode that assists drivers on highways, lacks a fully-autonomous self-driving mode. When the driver, George Caldera, was asked for a comment by the Daily Mail, he allegedly told the British tabloid that he had shifted to the passenger seat and handed over control to the vehicle. “I switched this Tesla into a self-driving mode and it started to move. And wow! A robot on the track! I thought the flivver would come round, but it bumped straightly into it! I am so sorry, the robot looks cute. And my sincere apologies to the engineers.” Other than the strange quote, a rope can be seen on the far side of the road near the robot, and Promobot appears to fall over slightly before being passed by the car.

Robots and self-driving cars have captured the public’s imagination, but confusion over the capabilities of each have at times also served to confuse. For instance, the robots deployed to ward off homeless people in San Francisco and Waymo’s self-driving cars in Arizona, have both elicited visceral responses from the public. The integration of artificial intelligence into the urban fabric has a long and bumpy road ahead.

In Aarhus, Denmark’s second largest city, a consortium of architects, engineers, and manufacturers are advancing the capabilities of concrete construction formwork and advanced design. This effort culminated in a recently unveiled 19-ton prototype dubbed Experiment R.
The project, led by the Aarhus School of Architecture, Odico Formwork Robotics, Aarhus Tech, concrete manufacturer Hi-Con, and Søren Jensen Consulting Engineers, tackles the waste associated with concrete formwork through the use of a novel robotic fabrication method.
How does this new method work and why is it potentially so disruptive? According to the Aarhus School of Architecture, formwork is easily the most expensive aspect of concrete construction, making up to three-quarters of the total cost of a concrete project. Significantly reducing waste associated with the formwork process and the molds themselves boosts environmental performance and the economic feasibility of complex concrete geometries.
The project's new apparatus consists of a heated and electrically powered wire rotating at a speed of approximately 160 feet per second around a carbon fiber frame. This device is mounted atop a robotic arm, which can shape complex detailing. While a polystyrene mold was used for the formwork of Experiment R, the mechanism has the capacity to cut through harder materials such as stone and timber.
Conventional methods of formwork fabrication are significantly more laborious—a typical CNC milling machine is able to process an 11-square-foot surface in approximately three to five hours. In an action that Asbjørn Søndergaard, chief technology officer of Odico Formwork Robotics, refers to as “detailing the whole formwork in one sweep,” the new technology is able to process that same surface area in 15 seconds. Strikingly, this timescale is applicable to both straightforward and advanced design formwork.The 19-ton Experiment B prototype, installed adjacent to Aarhus's Marselisborg Lystbådehavn in July 2018, is an extreme example of what can be achieved with this new method, displaying future possibilities of construction. According to Søndergaard, it is the hope of the consortium that the highly optimized concrete formwork is translatable and ultimately adopted for everyday projects such as minor infrastructural works and standard residential or commercial development.
