Table-Top Self Driving With The Pi Zero

Self-driving technologies are a hot button topic right now, as major companies scramble to be the first to market with more capable autonomous vehicles. There’s a high barrier to entry at the top of the game, but that doesn’t mean you can’t tinker at home. [Richard Crowder] has been building a self-driving car at home with the Raspberry Pi Zero.

[Richard]’s project is based on the EOgma Neo machine learning library. Using a type of machine learning known as Sparse Predictive Hierarchies, or SPH, the algorithm is first trained with user input. [Richard] trained the model by driving it around …read more

Ultrasonic Array Gets Range Data Fast and Cheap

How’s your parallel parking? It’s a scenario that many drivers dread to the point of avoidance. But this 360° ultrasonic sensor will put even the most skilled driver to shame, at least those who pilot tiny remote-controlled cars.

Watch the video below a few times and you’ll see that within the limits of the test system, [Dimitris Platis]’ “SonicDisc” sensor does a pretty good job of nailing the parallel parking problem, a driving skill so rare that car companies have spent millions developing vehicles that do it for you. The essential task is good spatial relations, and that’s where SonicDisc …read more

Self Driving Potato Hits the Road

Potatoes deserve to roam the earth, so [Marek Baczynski] created the first self-driving potato, ushering in a new era of potato rights. Potato batteries have been around forever. Anyone who’s played Portal 2 knows that with a copper and zinc electrode, you can get a bit of current out of a potato. Tubers have been powering clocks for decades in science classrooms around the world. It’s time for something — revolutionary.

[Marek] knew that powering a timepiece wasn’t enough for his potato, so he picked up a Texas Instruments BQ25504 boost converter energy harvesting chip. A potato can output around  …read more

Autonomous Delivery and the Last 100 Feet

You’ve no doubt by now seen Boston Dynamics latest “we’re living in the future” robotic creation, dubbed Handle. [Mike Szczys] recently covered the more-or-less-official company unveiling of Handle, the hybrid bipedal-wheeled robot that can handle smooth or rugged terrain and can even jump when it has to, all while remaining balanced and apparently handling up to 100 pounds of cargo with its arms. It’s absolutely sci-fi.

[Mike] closed his post with a quip about seeing “Handle wheeling down the street placing smile-adorned boxes on each stoop.” I’ve recently written about autonomous delivery, covering both autonomous freight as the ‘killer app’ …read more

Autopilots Don’t Kill Drivers, Humans Do

The US National Highway Traffic Safety Administration (NHTSA) report on the May 2016 fatal accident in Florida involving a Tesla Model S in Autopilot mode just came out (PDF). The verdict? “the Automatic Emergency Braking (AEB) system did not provide any warning or automated braking for the collision event, and the driver took no braking, steering, or other actions to avoid the collision.” The accident was a result of the driver’s misuse of the technology.

This places no blame on Tesla because the system was simply not designed to handle obstacles travelling at 90 degrees to the car. Because the …read more

Self-Driving Cars Are Not (Yet) Safe

Three things have happened in the last month that have made me think about the safety of self-driving cars a lot more. The US Department of Transportation (DOT) has issued its guidance on the safety of semi-autonomous and autonomous cars. At the same time, [Geohot]’s hacker self-driving car company bailed out of the business, citing regulatory hassles. And finally, Tesla’s Autopilot has killed its second passenger, this time in China.

At a time when [Elon Musk], [President Obama], and Google are all touting self-driving cars to be the solution to human error behind the wheel, it’s more than a little …read more

[Geohot]’s Self-Driving Car Cancelled

George [Geohot] Hotz has thrown in the towel on his comma one self-driving car project. According to [Geohot]’s Twitter stream, the reason is a letter from the US National Highway Traffic Safety Administration (NHTSA), which sent him what basically amounts to a warning to not release self-driving software that might endanger people’s lives.

This comes a week after a post on comma.ai’s blog changed focus from a “self-driving car” to an “advanced driver assistance system”, presumably to get around legal requirements. Apparently, that wasn’t good enough for the NHTSA.
