Just before midnight Saturday, one day before the final presentation, the project came to a dead stop.
The following Monday, the student aerospace engineering team was scheduled to perform a live test of their prototype land exploration rover to a high-profile client. But the microcontroller—the circuit board that commands the rover—was fried.
An octopus tentacle can perform tasks as complex as opening a jar and can continue to function after being severed from its body, thanks to a concentration of neurons in the tentacle itself. Researchers in the Correll Lab at CU-Boulder created a robotic hand nearly as dexterous and self-contained, winning the RoboSoft Grand Challenge manipulation competition in Livorno, Italy, April 29-30.
The landscape of Denver’s Westwood neighborhood is changing. Squash, tomatoes, chiles, spinach and melons are sprouting up in backyards. Family members are tending to their gardens and harvesting their own fresh food.
