Boys with wooden clubs in German-occupied Lwów, Poland (now Lviv, Ukraine) chase a battered and bloodied Jewish woman during the Lviv pogroms. Between 30 June to 2 July, and 25 to 29 July in 1941, approximately 5,000 of Lviv’s Jews were killed by German Einsatzgruppen paramilitary death squads and Ukrainian nationalists, militias and police. Thousands more were beaten, stripped naked, humiliated and deported to concentration camps. July 1941.
Robotic recreation of the Kangaroo form put together by Festo to demonstrate energy-efficient movement (this was initially announced on April the 1st, but turns out to be real) - video embedded below:
With the BionicKangaroo, Festo has technologically reproduced the unique way a kangaroo moves. Like its natural model, it can recover the energy when jumping, store it and efficiently use it for the next jump.
On the artificial kangaroo, Festo intelligently combines pneumatic and electrical drive technology to produce a highly dynamic system. The stable jump kinematics plus the precise control technology ensure stability when jumping and landing. The consistent lightweight construction facilitates the unique jumping behaviour. The system is controlled by gestures.
