Darwin Mini
This robots is the Darwin robot little brother. The good thing is that it is smaller and I think it would be much cheaper.
1) Description
I don’t have too much information about it but I think Robotis will release all the information as they did before with the old Darwin version. At this very moment this robot will use Dynamixe XL-320 Servos with CM-904a driver board and LiPo batteries.
The revolution of this robot is the servo size. They are strong enough to handle the robot but the prize is much cheaper. Robotis hasn’t release the product yet but the rumors says that it will be lower than USD$30. All the servo system would cost about ( USD$18 x 30 = USD$540) USD$600 that is much cheaper than the earlier version.
Dynamixel XL-320 Servo Specifications:
Weight- 16.7g Dimensions- 24.2mm x 36mm x 24mm Min Angle- 0.29 degrees Gear Ratio- 238:1 Stall Torque- Approximately 4 kgf.cm (at 7.4V) No load speed- Approximately 114 RPM (at 7.4V) Operating Voltage- 6-8.4V (7.4V recommended) Link (Physical)- TTL Level Multi Drop Baud rate- 7843bps - 1 Mbps Feedback- Position, temperature, load, input voltage, etc.
About the controller, OpenCM themes are low-cost, open source, convenient, and expandable.
The OpenCM product line starts with an extremely attractive Arduino like controller board specifically designed for robot use, the OpenCM 9.04.

The company expects it to sell worldwide for about USD$10.

And now let’s see how it moves.
