Lexis-Nexis, the on-line information service of Reed Elsevier, reports Sony has developed the industry's first small speakers made completely from recycled material. Milk cartons are among the materials used to manufacture the speaker cabinets. In fact, about 75% of the assembly is made from recycled paper. The assembly and components also contain 20% polyester foil and 5% aluminum, all of which did service elsewhere. Moreover, since no adhesives were used in construction, the material is recoverable and used yet again. If incinerated, the material produces no overly toxic fumes. The speakers themselves measure 17 cm across, 42 cm high, and 29 cm deep. They are considerably more pricey than comparable speakers made from non-recycled materials--about 40% more--but Sony is confident European demand for environmentally friendly products will move units off store shelves. Sales will begin in Switzerland, Austria, and Holland and the speakers will be generally available throughout Northern Europe as 1998 progresses.

The landscape of product development is changing. Electronic components and the devices that use them are shrinking, while power and functionality are rising. As a result, heat management is now in the forefront of the design process.
Ahead of their appearance at Design & Manufacturing Minneapolis, we look at some of the engineering behind two robots from the hit show, BattleBots, as well as some tried-and-true fighting tactics engineers should keep in mind when taking their own robots into battle.
