Google owned Boston Dynamics' Spot is a four-legged robot designed for indoor and outdoor operation. It is electrically powered and hydraulically actuated. Spot has a sensor head that helps it navigate and negotiate rough terrain. Spot weighs about 160 lbs.
The spider is a male Maratus speciosus (Coastal peacock spider) and this is its way to appeal to a potential female mate (the brown spider at the end). It is approximately 4 mm in length and inhabits coastal dunes near Perth in Western Australia.
