In its annual competition, the First LEGO League (FLL) is asking participants to design, build, and program a robot that addresses the needs of physically disabled people. The competition, open to kids ages 9-14, lets competitors use LEGO bricks and other parts such as sensors, motors, and gears to build a structure that conforms to the theme of the year. Opportunities are available to organize or coach a team. Registration ends in September. To learn more go to http://rbi.ims.ca/3853-523.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
