Spider-shaped robot can access inhospitable terrain

The creators at Fraunhofer’s Institute for Manufacturing Engineering and Automation IPA believe the high-tech spider will be able to act as an exploratory tool to access places too difficult or dangerous for humans following events such as natural catastrophes or industrial accidents.

The robot has been created using an additive manufacturing technique that involved applying layers of a fine polyamide powder with the aid of a laser beam. This allowed the team to create the complex geometries, inner structures and lightweight components required for the robot.

Ralf Becker, project manager for additive manufacturing at IPA, told The Engineer: ‘At the moment, the prototype robot is programmed to walk in a specific style. In future, however, it will be upgraded with sensors and may become autonomous.’

The 1kg robotic arachnid will eventually have a built-in camera that is capable of broadcasting live images to humans on the ground. Becker said it will also carry several other sensors and feed back information on environmental factors such as the concentration of toxic gases in a given area.
