That's why bikes used to use chains. Seriously, though, this column points to a common design flaw found in many products, where there's a single point of failure. And when I say point, I mean it literally, in that it often comes down to a single screw or fastener. Further, when that fastener comes loose (and usually not in the way it was intended; i.e., it comes out violently), you often get a stripped, ripped, or otherwise broken mounting point, which makes repair difficult.
Wow, that's one scary possible outcome from one very small design flaw. Just goes to show how important every component can be and why design for failure mode and effects analysis needs to be a critical part of the development workflow.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
