Dynamixel 2-Axis Actuator 2XC430-W250-T

Dynamixel markets its first 2-axis servomotor

The 2-axis 2XC430-W250-T servomotor resembles in many ways the TTL-connected X-series servomotors from the Robotis laboratory. It is compact, robust and programmable from A to Z thanks to the Dynamixel SDK.

The latest generation Dynamixel servomotors offer a resolution of 4096 pulses per revolution. They allow multiple control modes (speed, PWM, position...), and an ultra-complete feedback. Up to 253 configurable IP addresses allows the creation of very complex projects.

What makes the 2XC430-W250-T so different? The simultaneous management of 2 axes of movement.

2 DoF for a single servomotor

In any articulated robotics project, the number of degrees of freedom is usually defined by determining the number of connected servomotors. The 2XC430-W250-T servomotor achieves the same level of performance as a single-axis servomotor.

And yet, it manages two axes of movement, the first at the back, the second at the side. The design of the servo allows it to place the cables in such a way as to avoid any friction.
