Starsky Robotics - Radley Marx

Starsky Robotics is an autonomous trucking company working to make trucks autonomous on the highway and remote controlled for the first and last mile

Synopsis

Starsky Robotics was working on an autonomous vehicle solution with a clever twist. They would use a remote-driver (aka teleoperation) for anything their AI system couldn't handle.

I was responsible for making the teleoperation program succeed. I started with a rough prototype that could drive 10 mph on a straight road. By the time I finished, we had two teleoperation centers driving trucks in live traffic.

The challenge

The founders wanted to demo in less than 100 days

We needed to demonstrate a “gate-to-gate” trucking run using only the teleoperation and autonomous systems.

My role

I was Senior UX Designer and the only employee working specifically on the teleoperation program.

I designed the system hardware & software, developed the training program, and coordinated with the founders and autonomous team for access to resources.

INITIAL ASSESSMENT

The HUD displayed video streamed from a 180° camera mounted in the truck. At the bottom of the screen are indicators for speed and steering-wheel rotation.

Driving tests took place in a busy open-office environment. The remote driver and safety driver in the truck could not talk directly. All communication was relayed by engineers on cell phones.

The easiest way to drive adoption for an experimental system is to make it feel natural and familiar

I relocated the control station to a private room. I upgraded all the equipment to make the driving experience more true to life. Microphones and speakers were installed so the drivers could talk directly.

Poor video visibility was an ongoing challenge. Some of my solutions included:

apply a matrix algorithm to warp the video fit the screens
split the cell signal between services to reduce dropouts
repositioning the driver camera so percieved speed matched actual speed

Safety & confidence

Drivers need situational awareness at all times

The system was prone to problems like disconnections and signal loss. I immediately added error alerts and system status indicators. They were prominently displayed in the teleoperation control station and safety driver HUD.

We also established verbal communication during handoffs. Drivers were required to confirm "I have control / you have control.” They practiced various safety drills at the start of every training session.

Start with a video game

I installed American Truck Simulator in the control station so new remote-drivers could get used to the interface before handling a real truck.

Hands-on training was incremental. We started with slow figure-eights, handoffs, and safety drills. Drivers gradually learned how to apply the brakes and make turns without tossing everyone around in the truck.

Over time, we were able to move from a closed lot to low-traffic areas. After that was driving with a trailer, driving on the highway, on-ramps, off-ramps, and eventually in street traffic.

SYSTEM Design

Designing for scale

The initial prototype was a one-to-one system with one truck linked to the station. A developer had to update code so we could switch between trucks.

I separated the admin settings from the driver station so the station only contained video, indicators, and controls. The admin station slowly expanded into managing multiple trucks and tracking their location, speed, fuel levels, and cell strength.

A month before the demo, I opened a new teleoperation center in Florida. This required us to develop new safety checks to prevent conflicts between operation centers.
