The AX-12+ Dynamixel Servomotors are some of the most efficient servomotors of the market.
These servomotors are controlled with a 1Mbps serial link and can be linked as a daisy-chain. Up to 254 servomotors can be connected to the Dual-POB with only one cable.

These motors have 1024 steps and the speed can be fixed with a resolution of 1024 too.
In read mode, it is possible to know their current position, their speed and the applied torque...
Thus, it is possible to detect contacts with an obstable, wheels spinning or a slope with no additional sensors.

The features of these servomotors allow the user to realize a large panel of applications.
Intelligent actuator that returns information on its state, the AX-12+ servomotor allows any kind of robotics mountings while reducing the number of needed sensors.

Connect up to 254 AX-12+ servomotors to the Dual-POB with the serial link.
The Dual-POB knows and manages the position, the torque and the speed of the motors.
The Dual-POB can be used as a super I/O device for the LEGO NXT Mindstorm, it is possible to manage the AX-12+ servomotors from the NXT.
