Drone obstacle avoidance in 2003: 264 pixels and 8-bit processors

Figure 1: (left) Foam drone with optical flow sensor mounted under a wing, Summer 2001. (right) Foam drone with optical flow sensors for attempted obstacle avoidance, Summer 2002. Today it is universally acknowledged that drones operating close to the ground need some sort of obstacle avoidance. What I am about to tell is the story of our own first attempt at putting obstacle avoidance on a drone, during the years 2001 through 2003, using neuromorphic artificial insect vision hardware. I enjoy telling this story, since the lessons learned run contrary to even current practice but, upon reflection, should be common sense. I learned an important lesson that is still relevant today: The best results are obtained with a systemic approach in which the drone and any obstacle avoidance hardware are holistically co-…

UAVCAN v1.0 is here

Greetings. This is a cross-post from the ArduPilot blog. UAVCAN was first announced six years ago, in early 2014, as an RFC doc published on this website. Over the following few years, it saw adoption in numerous systems – mostly UAV, naturally, but also including spacecraft, micromobility vehicles, and even racing cars. The vast empirical data collected from fielded systems over the years allowed us to identify the weak points in the design and eventually enabled us to come up with the rectified, field-proven stable design which we call UAVCAN v1.0. The stable version was first announced about 18 months ago. Expectedly, the fact that v1.0 breaks wire compatibility with the original design based on that first RFC caused concern among the adopters. The resistance is understandable …

New Funko Pop Figurine Proceeds to Benefit Australian Bush Fire Victims

Since September 2019, heavy bush fires have consumed much of the Australian landscape. The fires, now mostly contained, thanks to heavy rains across the country, have destroyed upwards of 10,000,000 acres.  Additionally, more than 1 billion of the region’s wildlife population have perished due to these fires. 33 human lives have also been lost. American toy maker Funko, seeing the dire situation, came forward in support of the country and it’s cleanup efforts. Funko is releasing a limited-edition Funko pop figurine for Australian firefighters. The toy, named, Bush Fire Heroes features the Koala, whose habitat has been nearly completely destroyed. The brand, Funko is joining forces with a series of animal protection organizations.  A portion of each figurine’s proceeds of $19.99  will be donated to the Royal…

Jonah’s Hands: How the 11-Year-Old Crocheting Prodigy is Changing the World

Inspiration comes in all shapes and sizes.  Jonah Larson, abandoned as a newborn outside the small African town of Durame, Ethiopia is changing the world. The, now the 11-year-old, crocheting prodigy has built an empire using only his two hands and huge heart. When he was just 5 months old, he was adopted by Jennifer and Christopher Larson, residents of La Crosse, Wisconsin. From a young age, doctors suspected developmental disabilities and believed it would lead to a struggle with learning as a child. While he did struggle in school at an early age, it was not due to his developmental capabilities.  Instead, Jonah  was acting out and distracting others, his energy was off the charts. At age 5, a hook left in a craft basket helped him …
