Expansion of Robocar Operations in Frisco

Robot cabs have been seen in San Francisco for years, first by Uber, then by Cruise and Waymo. But there have been various restrictions on their operation in the past. NBC BAY AREA reported on August 10, 2023: “California regulators on Thursday approved an expansion that will allow two rival robotaxi services to operate throughout San Francisco at all hours, despite safety worries spurred by recurring problems with unexpected stops and other erratic behavior that resulted in unmanned vehicles blocking traffic, including emergency vehicles.” (NBC BAY AREA, 10 August 2023) It goes on to say: “The California Public Utilities Commission voted to approve rival services from Cruise and Waymo to operate around-the-clock service. It will make San Francisco first major U.S. city with two fleets of driverless vehicles competing for passengers against ride-hailing and taxi services dependent on humans to operate the cars.” (NBC BAY AREA, 10 August 2023) It is highly likely that accidents will occur, including personal injury. A city is a highly complex environment, and the technology for autonomous driving is far from mature. In addition, the population and tourists are not sufficiently prepared for this form of traffic.

The Robot-elevator Project

An elevator is still a bit of a problem for a service robot. A first approach is to use social features such as facial expressions and sounds. The user trusts the machine or feels sorry for it and helps it into the lift. A second option is for the robot to press the right buttons with its gripper. However, this can be very difficult and can also cause problems, for example when people are present. A third option is for the robot and the elevator to communicate via appropriate interfaces. This is certainly the most elegant solution, but it requires some technical standardisation and upgrading. As reported by the Korea Economic Daily, KT, LG Elec, and Hyundai Elevator have joined forces in the “robot-elevator project”. The vision is described in the teaser as follows: “A robot freely gets on and off an elevator and moves around a building, doing everything from coffee to parcel delivery and route guidance.” (KED, 28 July 2023) About the plans of the three companies, the magazine says: “The three will jointly plan and search for elevator-robot linkage services, con-duct cooperation to secure competitiveness in robotics services and look for new business lines. KT and LG Electronics said a far more competitive system of robotics services is possible by linking an elevator to a robot since robots must freely move between floors to increase their utility.” (KED, 28 July 2023) More information is available at www.kedglobal.com/robotics/newsView/ked202307280005.

Disabling Autonomous Vehicles

“Anti-car activists have come up with a novel and effective way of disabling driverless vehicles owned by Waymo and Cruise in San Francisco: placing traffic cones on their hoods. It’s the work of a group called Safe Streets Rebel, which has launched a protest dubbed ‘Week of Cone’.” (Techspot, 11 July 2023) This was reported by Techspot on 11 July 2023. Prof. Dr. Oliver Bendel has been pointing out for several years that automated and autonomous cars can be crippled in a simple way. On 6 March 2018, in an article in a Swiss IT journal, he asked, “Does autonomous driving fail because of manipulated sensors?” … A thesis by his student M. Hashem Birahjakli then systematically compiled and examined methods and means. A blog post about it states: “The results of the work suggest that every 14-year-old girl or boy could disable a self-driving car. So far, hacking has been seen as the greatest threat to autonomous driving. But while not everyone can hack, almost everyone carries chewing gum or lipstick. The automotive industry should consider this threat seriously.” The operator Waymo reacts helplessly to the actions. According to the German magazine Golem, a press spokesman emphasized that the traffic cone action shows a lack of understanding of how autonomous vehicles work and is vandalism. In fact, the activists know very well how autonomous vehicles work. And that is precisely the problem.

The Rise of the Humanoid Robots

If a report in Wired is to be believed, humanoid robotics has entered a decisive phase. The editor describes the case of Figure AI. This company from Sunnyvale, CA is building a humanoid robot for warehouse work and recently announced $70 million in investment funding. Chief Technology Officer Jerry Pratt is one of the key figures. “Pratt says his company’s robot is taking its first steps around a mocked-up warehouse in Sunnyvale, California. Brett Adcock, Figure’s CEO, reckons it should be possible to build humanoids at the same cost of making a car, providing there is enough demand to ramp up production.” (Wired, 25 May 2023) According to Wired, Figure AI is not the only company betting that humanoid robots are maturing. “Others include 1X, Apptronik, and Tesla.” (Wired, 25 May 2023) Tesla’s Optimus recently made an appearance on stage that was much more convincing than the first. By the way, it looks similar to the Figure AI model. Improvements in the robots can be seen in motor skills, but also in perception and control. Language models like PaLM-E could play an important role here in the future.

Robots in Hawai’i – Part 7

Mauna Kea volcano is the highest mountain in the world, measured from the bottom of the sea. It is considered a sacred place in the culture of Hawai’i. In this context, the famous and important telescopes on the top are always the cause of bitter disputes. The operation of drones is also not allowed on the mountain. However, a small robot made it on it in 2008. This was reported by several media outlets, including Science Daily. “During the field experiment, Nov. 1-13, the robot called Scarab will simulate a lunar mission to extract water, hydrogen, oxygen and other compounds that could potentially be mined for use by future lunar explorers. The four-wheeled robot will trek to different sites, using a Canadian-built drill to obtain a one-meter geologic core at each site. Each core will be chemically analyzed by on-board instruments developed by NASA.” (Science Daily, 14 October 2008) After that, it became increasingly difficult for robots to climb Mauna Kea. It is easier for scientists and tourists, who only need 4-wheel drive and robust health.

Robots in Hawai’i – Part 2

Ruby Tuesday is a popular restaurant in Hawaii (Hawaiian: Hawai’i), on the island of O’ahu. The location close to the airport is not one of the most beautiful ones. The food is also not praised by everyone. But the restaurant is known for its artificial staff. “Our KEENON DINERBOT is helping the staff here deliver trays and plates, so that they can pay more attention to improving customer satisfaction.” This is the message in a promotional video from Keenon Robotics in Singapore. The robot is a classic transport and serving robot. It has large, square blue eyes. In Europe and Asia, BellaBot is best known. It has a cat face and cat ears and is controlled via user input and voice commands. The European model Plato is also shaking up the market. Khon2, a platform from Hawaii, first reported on the new employee at Ruby Tuesday in 2022. “Staffing is such a problem now. Everything from managers down to servers and kitchen help cooks so this really helps our servers out,” Ruby Tuesday owner Rick Nakashima told Khon2 journalists. Indeed, robots of this kind seem to be at least a band-aid for the shortage of skilled workers. Customers’ reactions vary. Some seem to find the robots entertaining. Others say that direct contact with waiters is important to them. The restaurant emphasises that the robot is not intended to replace waiters. Rather, the robot acts as a support.

Robots in Hawai’i – Part 1

Hawaii (Hawaiian: Hawai’i) is not necessarily associated with robots. But in the larger cities, you can be sure to encounter them. There are service robots such as the Keenon Dinerbot and surgical robots such as the da Vinci Surgical System. In addition, robots are used in the wild, for example for nature conservation. The hospital group in the east of the archipelago advertises with the following words: “East Hawaii Health Clinics is excited to introduce our fully operational robotic surgery center. This state-of-the-art equipment allows us to perform minimally invasive surgeries that would otherwise require greater surgery time and recovery time. We look forward to continuing to provide East Hawaii with exceptional surgical options.” (Website East Hawaii Health Clinics) This type of care is available in Hilo, among other places. The small town on the Big Island has the latest medical technology, such as that used in Basel and Berlin. Hilo is surrounded by tropical rainforest. Nearby are Akaka Falls and Hawai’i Volcanoes National Park. In the city itself, giant banyan trees grow. One must not forget the many homeless people who are at the end of their tether. Like California, Hawai’i has not dealt with this problem. These people will never be able to afford treatment with a surgical robot.

Mind-controlled Four-legged Robot

“Researchers from the University of Technology Sydney (UTS) have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought-control.” (UTS, 20 March 2023) This was reported by UTS on its website on March 20, 2023. The brain-machine interface was developed by Chin-Teng Lin and Francesca Iacopi (UTS Faculty of Engineering and IT) in collaboration with the Australian Army and Defence Innovation Hub. “The user wears a head-mounted augmented reality lens which displays white flickering squares. By concentrating on a particular square, the brainwaves of the operator are picked up by the biosensor, and a decoder translates the signal into commands.” (UTS, 20 March 2023) According to the website, the technology was demonstrated by the Australian Army, where selected soldiers operated a quadruped robot using the brain-machine interface. “The device allowed hands-free command of the robotic dog with up to 94% accuracy.” (UTS, 20 March 2023) The paper “Noninvasive Sensors for Brain–Machine Interfaces Based on Micropatterned Epitaxial Graphene” can be accessed at pubs.acs.org/doi/10.1021/acsanm.2c05546.
