From Wikipedia, the free encyclopedia
Selected Pictures are images from Engineering-related articles that we feel match the following four criteria. These images should:
- illustrate a complex or unusual topic elegantly
- be of sufficiently high quality and resolution to be displayed at 300x300 pixels (or so)
- portray an aspect of engineering currently or previously employed (no science fiction)
- be aesthetically pleasing, and invite the user to learn more about the topic
Previous images and their accompanied text are included below, in chronological order.

A radome is a weatherproof enclosure used to protect an antenna. It is used mainly to prevent ice (especially freezing rain) from accumulating directly onto the metal surface of the antenna. In the case of a spinning radar dish antenna, the radome also protects from debris and rotational irregularities due to wind. On aircraft in addition to giving protection, the radome streamlines the antenna reducing drag. (Credit U.S. Navy, [2])
A robot is a mechanical device that can perform preprogrammed physical tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a pre-programmed computer. Robots may be used to perform tasks that are too dangerous or difficult for humans to implement directly (e.g. the space shuttle arm) or may be used to automate repetitive tasks that can be performed more cheaply by a robot than by the employment of a human (e.g. automobile production).
