- | The hand uses the latest **EROS Architecture** for electronics and software comprised of one main processor - ARM Cortex M4 - and 4x dedicated ATMEGA processors (one on each smart actuator), for distributed and scalable processing of low level motion control. | ||
The unit is capable of receiving commands simultaneously from multiple interfaces: main connector (RS485 or TTL), USB and optionally Bluetooth. | The unit is capable of receiving commands simultaneously from multiple interfaces: main connector (RS485 or TTL), USB and optionally Bluetooth. | ||
- | |||
- | To **control the unit and query its status, the unit exposes Control Tables** (a memory-mapped kind of abstraction) where you can write to specific addresses to control the unit or read from other addresses to get real time status information.\\ | ||
- | A full query cycle usually takes less than 5ms (average 3ms), **enabling closed loop control frequencies of up to 200~250 Hz.** | ||
- | |||
- | Reading and writing the control table is done using the Robotis Dynamixel Protocol (a Serial protocol) or through the Seed Robotics own Text protocol.\\ | ||
- | **Users of Robotis products** should also know that the Control table works under the **Dynamixel 1.0 protocol (AX, MX series) and optionally under the Dynamixel 2 protocol**, for compatibility with the Robotis XM and Pro series.\\ | ||
- | Such flexibility makes the units directly compatible with Robotis Dynamixel based assemblies and frameworks such as Robotis OP/OP2 Framework, Dynamixel SDK, ROS, PyPot and others.\\ | ||

- | === NOTICE: Change from the Ares to Eros Architecture === | ||
- | |||
- | As of March 1st 2017, we began shipping the RH4D with the new, scalable Eros Architecture.\\ | ||
- | While the external interfaces remain mostly the same, the new architecture scales much better and makes better distribution of processor load for improved performance. | ||
