Researchers from École polytechnique fédérale de Lausanne(EPFL), Switzerland, have developed this robotic arm which is capable of catching flying objects with complex shapes and trajectories in less than five hundredths of a second. In the near future, this arm is going to help catch dust or unknown objects in the outerspace.
The length of the arm is 1.5m, and it has been tested to catch balls, empty bottles, half-filled bottles, hammers and tennis rackets with 5 different circumstances. Take the half-filled bottle for example, when it is flying, the location of its center of gravity may change according to the movement, which causes complex motion trace. Once the robotic arm can overcome this difficulty, it can be used widely in any fields.
