Paralyzed individuals successfully use brain waves to operate tablet computers
In a collaborative study presented by scientists primarily affiliated with Stanford and Brown Universities, participants suffering from significant paralysis were successfully able to use non-modified applications on an Android tablet using their brain waves. In previous studies, “point-and-click” computer functionality interpreted from these kinds of signals has been accomplished, but the applications available to participants was limited to software and devices that had been specialized and personalized for users’ specific needs. This study has demonstrated technology that overcomes this limitation and enables access to the full range of software available to non-disabled users. Participants enjoyed applications previously unavailable to them such as streaming music services and a piano keyboard player.
To accomplish the study’s objectives, scientists capitalized and combined existing technologies for their unique end. Brain waves from participants’ brain implants were sent to a commercially available recording system and then processed and decoded by an existing real-time interpreter software. The decoded data was then transmitted to a Bluetooth interface configured as a wireless mouse which was paired to an Android tablet. While the steps to accomplish the task at hand are many, the result somewhat resembles telepathy but largely resembles greater accessibility for the disabled.
Individuals suffering from various forms of paralysis generally have difficulty using communication technologies. Strokes, neurological injuries, and neurodegenerative diseases such as ALS (Amyotrophic Lateral Sclerosis) can all lead to limited physical functionality that impairs the use of communication devices. However, although physical mobility is affected by paralytic conditions, the brain often continues to send signals to muscles to trigger movement. Using this attempted signaling, scientists have been developing technology to bridge the disconnect between the brain’s signals and the intended outcomes.
Brain-computer interfaces (BCIs) record activity in the brain and interpret that data to generate an action. Using microelectrode arrays implanted into areas of the brain corresponding to desired functionality, neural signals are transmitted to the array’s plates or shanks that interpret their activity into usable data. All of the participants in this study had implants placed in the hand area of their brains’ dominant motor cortexes from which signals were recorded. Since computers inherently operate via digital signals, they stand as promising tools to facilitate communications originating from BCIs. In particular, algorithms developed using machine learning have been designed to interpret brain signals into computer mouse movement, a capability which can be expanded into software accessibility.
One of the study’s researchers, Krishna V. Shenoy, is a consultant for Neuralink Inc., Elon Musk’s brain-computer interface company. While BCIs in general have similar goals to Neuralink’s, the major difference is in purpose, namely in that Musk’s company aims to enhance human capabilities to better compete with artificial intelligence rather than restoring or improving lost abilities. Where BCIs interpret existing brain signals to reenable preexisting capabilities, Neuralink hopes to merge computing and brain power into a seemingly singular function via tiny, dust-sized particles rather than traditional implants.

Tesla lands approval for Robotaxi operation in third U.S. state
On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in.
Tesla has officially landed approval to operate its Robotaxi ride-hailing service in its third U.S. state, as it has landed a regulatory green light from the State of Arizona’s Department of Transportation.
Tesla has been working to expand to new U.S. states after launching in Texas and California earlier this year. Recently, it said it was hoping to land in Nevada, Arizona, and Florida, expanding to five new cities in those three states.
On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in:
BREAKING: Tesla has officially received approval from the Arizona Department of Transportation to launch its Robotaxi service on public roads in the state!

Tesla has also been working on approvals in Nevada and Florida, and it has also had Robotaxi test mules spotted in Pennsylvania.
The interesting thing about the Arizona approval is the fact that Tesla has not received an approval for any specific city; it appears that it can operate statewide. However, early on, Tesla will likely confine its operation to just one or two cities to keep things safe and controlled.
Over the past few months, Robotaxi mules have been spotted in portions of Phoenix and surrounding cities, such as Scottsdale, as the company has been attempting to cross off all the regulatory Ts that it is confronted with as it attempts to expand the ride-hailing service.
It appears the company will be operating it similarly to how it does in Texas, which differs from its California program. In Austin, there is no Safety Monitor in the driver’s seat, unless the route requires freeway travel. In California, there is always a Safety Monitor in the driver’s seat. However, this is unconfirmed.
Earlier today, Tesla enabled its Robotaxi app to be utilized for ride-hailing for anyone using the iOS platform.

Tesla ride-hailing Safety Monitor dozes off during Bay Area ride
We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.
A Tesla Robotaxi Safety Monitor appeared to doze off during a ride in the California Bay Area, almost ironically proving the need for autonomous vehicles.
The instance was captured on camera and posted to Reddit in the r/sanfrancisco subreddit by u/ohmichael. They wrote that they have used Tesla’s ride-hailing service in the Bay Area in the past and had pleasant experiences.
However, this one was slightly different. They wrote:
“I took a Tesla Robotaxi in SF just over a week ago. I have used the service a few times before and it has always been great. I actually felt safer than in a regular rideshare.
This time was different. The safety driver literally fell asleep at least three times during the ride. Each time the car’s pay attention safety alert went off and the beeping is what woke him back up.
I reported it through the app to the Robotaxi support team and told them I had videos, but I never got a response.
I held off on posting anything because I wanted to give Tesla a chance to respond privately. It has been more than a week now and this feels like a serious issue for other riders too.
Has anyone else seen this happen?”
My Tesla Robotaxi “safety” driver fell asleep

The driver eventually woke up after prompts from the vehicle, but it is pretty alarming to see someone like this while they’re ultimately responsible for what happens with the ride.

They should have probably left the vehicle immediately.
Tesla’s ride-hailing service in the Bay Area differs from the one that is currently active in Austin, Texas, due to local regulations. In Austin, there is no Safety Monitor in the driver’s seat unless the route requires the highway.
Tesla plans to remove the Safety Monitors in Austin by the end of the year.
Tesla has officially opened Robotaxi access to everyone and everyone, but there is one catch: you have to have an iPhone.
Tesla’s Robotaxi service in Austin and its ride-hailing service in the Bay Area were both officially launched to the public today, giving anyone using the iOS platform the ability to simply download the app and utilize it for a ride in either of those locations.
It has been in operation for several months: it launched in Austin in late June and in the Bay Area about a month later. In Austin, there is nobody in the driver’s seat unless the route takes you on the freeway.
In the Bay Area, there is someone in the driver’s seat at all times.
The platform was initially launched to those who were specifically invited to Austin to try it out.
Tesla confirms Robotaxi is heading to five new cities in the U.S.
Slowly, Tesla launched the platform to more people, hoping to expand the number of rides and get more valuable data on its performance in both regions to help local regulatory agencies relax some of the constraints that were placed on it.
Additionally, Tesla had its own in-house restrictions, like the presence of Safety Monitors in the vehicles. However, CEO Elon Musk has maintained that these monitors were present for safety reasons specifically, but revealed the plan was to remove them by the end of the year.
Now, Tesla is opening up Robotaxi to anyone who wants to try it, as many people reported today that they were able to access the app and immediately fetch a ride if they were in the area.
We also confirmed it ourselves, as it was shown that we could grab a ride in the Bay Area if we wanted to:

The launch of a more public Robotaxi network that allows anyone to access it seems to be a serious move of confidence by Tesla, as it is no longer confining the service to influencers who are handpicked by the company.
In the coming weeks, we expect Tesla to then rid these vehicles of the Safety Monitors as Musk predicted. If it can come through on that by the end of the year, the six-month period where Tesla went from launching Robotaxi to enabling driverless rides is incredibly impressive.
