The USB2AX is a small interface to control Dynamixel servos like the AX-12 from a computer. It plugs into a USB port and has a 3-pin Dynamixel connector to be connected to the servos.
A typical use scenario is in a small mobile robot with a laptop or an embedded computer (like a Raspberry Pi) as a brain and servos to move legs, arms or claws.
- • Comunication with AX and MX Dynamixel servos (with 3 wires) @ 1Mbps
- • Very small (16x36mm)
- • Optimized latency
- • Protection against ESD and short circuits
- • Advanced functionalities: sync_read, bulk_read...
- • Windows / Linux / MacOS
- • Firmware updates
- • Open Source Software & Hardware, programmable and hackable!
What servos can it talk to?
- • Basically, it can talk with any device which uses a half-duplex TTL interface (3-pins connector) and the • Dynamixel protocol. More specifically:
- • All of the AX servos (AX-12/AX-12+/AX-12A, AX-12W, AX-18F/AX-18A).
- • The "T" versions of the MX servos (MX-28T, MX-64T, MX-106T).
- • XL-320 with an adapter cable (different connectors and power but compatible communication).
What can't it do?
- • The USB2AX can not communicate with the Dynamixel servos using the RS485 interface (the one with 4 pins).
- • Neither can it control any sort of hobby/RC servos or other brand of robot servos.
- • Compared to the USB2Dynamixel, it also lacks the RS232 port (with its big DB9 connector) used to • program some controllers from Robotis like the CM-510.
- • It can not supply power to the servos.
- • It is not a generic USB to Serial (even though it can be modified to be one) and has very different capabilities than the LN-101.
