Self-driving startup Voyage built a physical "Telessist Pod" with software that allows a remote operator to give instructions to a self-driving car. Iwastheone shares a report from Ars Technica "For all of this to work safely, it had to basically be a car without wheels," Voyage CEO Oliver Cameron told me in a Thursday phone interview. "It had to have a real steering wheel, real pedals, real automotive-grade connectors, and real automotive-grade ECUs." Voyage's engineers built a "car without wheels" because they wanted to mirror the experience of driving a real car as closely as possible. "If you try to do it with a gaming steering wheel, you don't get the force feedback" you get with a real car, Cameron said. "It's impossible to drive reliably like that. It's so unsafe." Remote Voyage drivers sit in a metal cage the size of a golf cart. There's a steering wheel, gas pedal, and brake pedal where you'd expect them in a real car. A wraparound array of computer monitors shows the car's surroundings. An encrypted wireless data connection keeps the components in the Telessist pod synchronized with their counterparts in the real car. Voyage says the network latency is under 100 milliseconds -- short enough that the driver won't notice a significant lag. In case something goes wrong, the company bonded together five separate cellular connections, each with its own SIM card on a different wireless carrier, to achieve maximum redundancy and hence reliability," reports Ars. "If one of the five networks fails, software automatically switches over to the other four." There's a system called Remote Drive Assist that will take over if the car loses its wireless connection. Voyage even added an emergency braking system, which consists of a small, self-contained lidar unit in front of Voyage's cars. "If it detects an imminent collision, it has the power to activate the brakes and bring the vehicle to a stop," adds Ars. "This means that, even if the human driver -- or Voyage's main self-driving system, for that matter -- makes a mistake, the car is unlikely to run into anything."
