The G-Dog boasts stable walking performance due to the four legs and new high performance servos.

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.

20自由度で腹部に搭載したハイトルクサーボによって上半身の前屈も可能。※自由度=関節の数量(サーボの数)

Due to 9 small and lightweight servos (9 joints) the G-Dog is capable of various motions including "sit" and "handstand".

TTL command/ PWM system servo RS304MD

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.

Main features of the servo

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 Processer. Built-in Temperature Sensor turns off power when servo temperature becomes too high. Servo operation characteristics can be changed according to preferred speed and torque. All the servos are calibrated and have the same performance.

The output shaft on each servo has a mark indicating the neutral position.
※The servo in the photo is not the one included in the product. We use this photo just because it clearly shows the mark.

Servos are connected via a hub.

"RPU-11" Processing Unit

"RPU-11" Processing Unit is used. G Sensor and Get-up Motion are included so the G-Dog automatically gets up on its own judgment after falling. In addition, 17 sample motions are pre-set. The G-Dog also comes with an input connector for a biaxial gyro (not included). The G-Dog has a START/STOP switch so that you can temporality turn off power without shutting down the power source to save electricity and change motions efficiently and safely.

Special Ni-MH Battery and Charger

Special Charger can fully charge Ni-MH Battery in about 3 hours.
The operation time is about 45 minutes, however, it varies depending on how the G-Dog is operated.

Special Controller and Special Receiver (Not included in the kit)

※Special Controller (RRC-T13) and Special Receiver (RRC-R13) are not included in the kit. Attaching Special Controller and Special Receiver enables you to control built-in motions without using a computer. Maximum 16 robots can be operated simultaneously.

Easy-to-assemble resin Main Frame

By adding Aluminum Bracket and Servo (not included), you can create more realistic motions.
You can also reassemble to make the G-Dog a two-leg robot.

Simple and realistic motions can be made by connecting Head and Tail with Link.

Attaching Ni-MH Battery (included ) at the bottom center of the belly makes the center of gravity low for stable walking performance. Special Charger can fully charge Ni-MH Battery in about 3 hours and the operation time is as long as 45 minutes.

By adding more axles with Aluminum Bracket and Servo (not included), you can create more realistic motions.
