    Social Robots - TechKnow

    Erica, who has a beautiful face and speaks with a synthesised voice, is one of the most advanced and autonomous androids in the world.

    The human-like robot was created in Japan in 2014 and was developed to be capable of conversational interaction. Since then, a total of four models have been engineered. She is unable to walk, but, in the summer of 2017, Erica (short for Erato Intelligent Conversational Android) was given an upgrade so she could move her arms, along with her head, neck and shoulders.

    "We are creating this new kind of entity that's not really a person but we can interact with it like a person ... It's not alive, it's there. And you do socially connect with it on a subconscious level. This is why robots that have a human form really are different from other robots. You don't bond in the same way with a vacuum cleaner," says Dylan Glas, guest associate professor at Osaka University, who has spent three years working on Erica.

    The use of robots in manufacturing is growing. According to the International Federation of Robotics, 1.7 million robots will be in service worldwide by 2020, with the leading robotics countries being China, South Korea, Japan and the US.

    There's fear in some countries around the world that robotics will eventually replace humans, but, in Japan, hopes are high that human-like robots can solve some of their problems.

    Japan's population is rapidly declining, and, according to the United Nations, its population is the oldest in the world. One of the suggested solutions is to replace workers with robots and use robots to take care of the elderly.

    TechKnow travels to Kyoto to meet social robots and the scientists behind them.

    The science of capturing carbon - TechKnow

    The science of capturing carbon - TechKnow

    The devastating effects of climate change are everywhere. Now, the fight to save the planet is taking an innovative turn. What if scientists could offset dangerous greenhouse gas levels by capturing CO2 from the atmosphere and putting it to use? This episode looks at two project that aim to capture CO2 and convert it into useable products.
    The first would combine basalt and CO2. Basalt is naturally highly reactive with CO2; when the two meet, they undergo a series of exchanges that culminate with the carbon precipitating out as a solid whitish substance, similar to limestone.
    The second project uses cyanobacteria to convert CO2 into bio products such as fuels, bioplastics, oils and flavourings.

    Is it too late to save Mexico's vaquita porpoise? - TechKnow

    Is it too late to save Mexico's vaquita porpoise? - TechKnow

    The vaquita is the world’s smallest cetacean, a miniature porpoise with what some describe as cartoonlike features, and dark smudges around its eyes. The marine mammal lives only in the fertile waters of the Mexico’s Gulf of California. The problem: it shares its habitat with the totoaba, a fish coveted by wealthy Chinese who believe it has mystical medicinal powers. The vaquita are trapped in illegal gillnets set for the totoaba.

    In this episode, TechKnow looks at the various efforts to save this exquisite animal from extinction. The Mexican Navy has attempted to patrol the waters of the gulf to stop this illegal fishing, but the region’s poor fishermen are easily lured by the big payday. The country’s environmental agencies have declared war on gillnets. Locals make their living off of shrimping, and they prefer gillnets. Replacement nets have been distributed, but old habits are difficult to break. In addition, Techknow boards a Sea Shepherd Conservation Society vessel. Their two vessels are on 24/7 patrols to protect the vaquita from illegal fishing.
