The energyShield is a rechargeable lithium-polymer battery in the form of an Arduino shield (Uno/Leonardo Compatible). It has three main internal functions including a circuit to boost the battery's nominal voltage of 3.7V to 5V; a lithium-polymer battery charging circuit; and an on-board fuel gauge IC which allows for the measurement of battery voltage, current, and accumulated charge by means of a Two-Wire Interface (TWI/I2C).
The Pi-Bot is a uniquely designed (and affordable!) complete robot kit for anyone interested in building and programming robots! Pi-Bot was engineered from the ground up through several design cycles to optimize function while staying affordable. They continue to work with students to make our designs appealing, and work with experts in the area of robotics to improve their designs. They field tested their Pi-Bots with a small group of high school and college students. The response has been remarkable. This is the kit you wish you had growing up!
Valkyrie (officially designated "R5" by NASA) is a 1.9 meter tall, 125 kilogram, 44 degree of freedom, battery-powered humanoid robot. A team from NASA's JSC in Houston, in partnership with the University of Texas and Texas A&M and with funding from the state of Texas itself, built the robot for the DRC, which will hold a preliminary competition later this month. JSC is a Track A team in the DRC; along with five other Track A teams with their own robots, JSC will be competing against Track B and C teams, each one of which will have an ATLAS robot from Boston Dynamics. In addition, Track D teams (which have no DARPA funding) will be entering their own robots.
