G-Dog is a fantastic kit robot that you cannot buy in America.
Nine small RS304MD servos (new command TTL/ PWM system) are used for the G-Dog. The G-Dog is a high performance and reasonably-priced four-leg robot coming with Processing Unit and Motion Editor. The G-Dog comes with 9 command-type robot servos and each servo has its own command ID. More servos can be added using a hub and no complex wiring is required. Command-type Control Servo contains a built-in CPU. Since servos receive commands for speed and directions for each movement and operate according to the commands, there is less load on Processor.Video demonstrates how fast and agile it is, compared to the sort of thing you can buy in the shops: G-Dog Servo Robot Dog by G-Robots [Hacked Gadgets]
