What would happen if a robot got hit by a train?
A couple of weeks ago, while waiting for a commuter train back to San Francisco from Redwood City, I had an unexpected and disturbing encounter with one of the "self-driving" motorized delivery robots that are currently being tested in Redwood City.
The robot -- a knee-high wheeled box about the size of a hassock fan or footstool -- was working its way along the edge of the platform, beyond the yellow line marking the danger zone, where it could have been struck by or sucked into a passing train and turned into 50 pounds of flying shrapnel. Some "Baby Bullet" express trains on that track go past the platform in Redwood City at 60 mph without stopping.
I was surprised to see one of these robots on the Caltrain platform at all, much less to see it trying to use the platform as a through passageway, and even more surprised to see it drive right up to the edge of the platform before it jerked to a stop and turned to continue along the platform toward me.
I yelled at the robot, hoping that a human operator might be monitoring it, but the only response from the robot was a repeated recorded message, "Let me go! I'm working! I'm going to be late!" -- as if the platform was a right-of-way, and humans were expected to yield to robots.
I saw no marking on the robot, but another passenger on the train had encountered a similar robot accompanied by a human minder earlier in the day. They passed on the card they'd gotten from the robot handler with the name of the company that operates the robots, "Starship Technologies".
The e-mail address on the business card didn't work, and there's no phone number on the company's Web site. I got in touch with a spokesperson for Starship Tech only after they responded to my Tweet about the incident. But almost three weeks later, and after multiple exchanges with staff of Starship Tech, Caltrain, and the government of Redwood City, I still haven't gotten any coherent explanation of what happened or why.
Last night, all else having failed, I took the Caltrain to Redwood City again to bring the issue before the city council. I hadn't planned on writing about this yet, but since I've heard that some of my comments from the webcast of the city council meeting are circulating and being discussed elsewhere online, I'm posting them here in full.
My name is Edward Hasbrouck, and I came down from San Francisco today to alert you to a serious safety issue involving the delivery robots that are operating here in Redwood City.
On August 9th, I was on the Redwood City Caltrain platform when I saw a delivery robot on the platform, out at the edge beyond the yellow line marking the danger zone. The robot went almost to the drop-off before it turned back, and then it tried to push along the platform through the crowd of people waiting for the oncoming train, playing a loud recorded demand that we move aside to let it pass.
There was no visible marking on the robot. There's no phone number on the Web site of the company, Starship Tech. Supposedly there's a 2 × 3" label on each robot with a phone number. But that's too small to read from any distance, and that phone number goes to voicemail, so it doesn't provide any way to communicate with the human operator or report problems in real time.
Caltrain told me they don't believe that the city permit authorizes use of the Caltrain platform by these robots. But a spokesperson for Starship Tech told me that the company intends to continue using the Caltrain platform as a robot thoroughfare at all times except 4 to 6 p.m.
One of the first things we teach small children before we let them out on the street is to stay away from train tracks. Similarly, keeping robots away from moving trains should have been a priority for robot programmers and operators.
This incident should be a wake-up call that the city needs policies and procedures to deal with the inevitable cases when robots get into places where they aren't allowed, aren't wanted, fail to yield to pedestrians, or cause a nuisance, tripping hazard, or even a greater danger.
Redwood City took the lead on this issue, and you are setting a precedent not just for this technology, but also for the regulatory framework in which it operates. You need to get this right, not just for your own sake but also for the sake of other cities following your lead. But because there wasn't yet any experience with these robots, some of the problems may not yet have been apparent.
Other cities and states that have more recently adopted rules for delivery robots have almost all included requirements that aren't part of the Redwood City pilot. These include an adequately sized label with an ID number and contact information on each robot, prompt responses to public inquiries, and reporting of safety incidents to the authorities.
People who see robots where they shouldn't be, or doing things they shouldn't do, need to be able to identify the robot, communicate the
problem quickly to the robot operator, and have their complaints reported to the city so it can learn from experience.
I request that the City Manager revoke the delivery robot permit until the permit conditions can be revised to deal with incidents such as this. If the City Manager does not do so, I request that you place on the agenda for your next meeting a resolution to suspend the pilot program and direct that the permit be rescinded pending revision of the rules for operation of these robots.
I could have gone into more detail if I hadn't been limited to three minutes. But I've already heard from the Mayor and one of the other members of the City Council today, promising that city staff will be looking into this matter further.
If you see a robot on any of the Caltrain platforms, please report it immediately to Caltrain staff, with a photo if possible. If you send me a copy of your report and/or photos, I'll also do what I can to get them to the relevant Caltrain and city staff.
