|Description:||From NSF's Multimedia Image Gallery. A system composed of multiple molecule robot modules can change its shape by moving modules from one location in the structure to a different location. This capability allows the system to adapt its shape to different tasks. The work is supported by National Science Foundation grants CNS 02-02789 and IIS 02-06306. (Date of Image: May 17, 2003) [One of six related images. See Next Image.] A self-reconfiguring robot consists of a set of identical modules that can dynamically and autonomously reconfigure in a variety of shapes to best fit the terrain, environment or task. Self-reconfiguration leads to versatile robots that can support multiple modalities of locomotion and manipulation. For example, a self-reconfiguring robot can aggregate as a snake to traverse a tunnel, then reconfigure as a six-legged robot to traverse rough terrain such as a lunar surface, then change shape again to climb stairs and enter a building. Researchers at MIT's Rus Robotics Laboratory have designed a small robotic module they call the Molecule that is capable of self-reconfiguration in a 3-D space. The Molecule is capable of independent movement on a substrate of identical Molecules, including straight-line traversal and 90 degree convex and concave transitions to adjacent surfaces. A Molecule robot consists of two atoms linked by a rigid connection called a bond. Each atom has five inter-Molecule connection points and two degrees of freedom. One degree of freedom allows the atom to rotate 180 degrees relative to its bond connection, and the other degree of freedom allows the atom (thus the entire Molecule) to rotate relative 180 degrees relative to one of the inter-Molecule connectors at a right angle to the bond connection.|
