BionicKangaroo is able to realistically emulate the jumping behavior of real kangaroos, which means that it can efficiently recover energy from one jump to help it make another jump. Without this capability, kangaroos (real ones) would get very very tired very very quickly, but by using their tendons like elastic springs, the animals can bound at high speeds efficiently for substantial periods of time.
BionicKangaroo emulates this with an actual elastic spring, which partially “charges” the legs on landing.
Bonus fun: wear the corresponding armband and you can control the kangaroo using gestures. Mmmmmmm, biomechanics.
Inspired by the water and brush calligraphy of older artists in his local Beijing parks, Hanna converted a Beijing tricycle, called a san lun che, to digitally “paint” (or more accurately drip) Chinese characters onto the sidewalk. The characters write out Dongcheng District Propaganda phrases that are on banners and housing developments in the district.
The trike would catch quite a bit of attention in the streets, as seen in these two 2011 videos by Jonah Kessel. According to Kessel, the tricycle drips:
营造 未成年人健康成长的良好环境 Create a good environment for minors to grow up healthy
文明从脚下起步 奉献从身边做起 Civilization comes from every individual, to contribute from every little thing
树文明新风 做文明市民 Be a civilized citizen and build a civilized new atmosphere for constructing s cultured and civilized city
共建文明城区 共享美好家园 Build a civilized city for everyone to share a beautiful home altogether
做文明有礼北京人 建和谐魅力新东城 Be civilized and polite Beijingers, to build a harmonious charm new Dong Cheng district together
美德贵在坚持 文明重在行动 Virtue shows through long term persistence, civilization reflects by actions
和谐东城 你我共建 Harmonious Dong Cheng District constructed by you and me
建全国文明城区 做东城文明市民 Constructs the national civilized district, to be the civilized citizen of Dong Cheng District
The project was first shown at Beijing Design Week in 2011. Hanna now lives in Los Angeles where he works as an artist and designer.
In the coming year, engineers will continue working on the prototype, which the company boasts will be lighter, safer, quieter and greener than any other helicopter in the world.
That’s because a traditional helicopter uses one rotor to provide lift and a tail rotor to prevent the aircraft from spinning in circles. It maneuvers by changing the pitch of the two rotors. The volocopter has 18 small rotors mounted in a configuration that provides lift without causing the vehicle to spin. It navigates by changing the speed of individual rotors.
