ROBOTIS OP3 is an affordable, miniature humanoid robot platform with advanced computational power, sophisticated sensors, high payload capacity, and dynamic motion ability to enable many exciting research and education activities.
OpenTracker v2 is the first 100% Arduino compatible, fully open source, commercial grade GPS/GLONASS vehicle tracker development board that comes with a free web interface for tracking.
The OpenTracker v2 hardware includes the same powerful 32-bit ARM controller as the Arduino DUE, a GSM/GPRS modem for wireless connectivity, a GPS/GLONASS module with Assisted-GPS, CAN-BUS, plenty of I/O, and a wide operating temperature range of -35°C to +80°C.
This is probably the smallest Arduino controller speically designed for controlling the servo. It features a 12 standard servo control capbility with Xbee socket which can be used to control helicopter or UAV via the Xbee link. The feather weight (7.5g) make it an ideal controller for those application that has limited payload. The build in regulator is allow the input voltage vary from 3.5-8V which fits the most power supply without any modification.
