Think of Anki Drive as a kind of three-dimensional video game. Developed by Anki (pronounced: On key), a San Francisco, Calif., robotics company, the product consists of a roll-up oval-track layout containing special built-in electronics that transmit data to optical sensors located beneath each racecar. The cars are controlled through an app that’s downloaded to your iPhone, iPod Touch or iPad, which turns the device into a Bluetooth-enabled remote. Anki Drive’s artificial intelligence (no Internet connection required) allows one player to compete against up to three other players or against the system that assigns specific characteristics to each car. Anki Drive is priced at $100 for the base starter set that includes two cars. Additional cars sell for $50 each. Anki Drive is available at www.anki.com.
