Motion data analysis of humanoid robot
The global process of “machine replacing human” is accelerating, and humanoid robot is expected to become the next important implementation application scenario of AI. EtherCAT-Analyzer can analyze the communication information of all joints and batteries of humanoid robot and master station, and quickly grasp the node network state!
Accurate analysis of motion data of humanoid robot
As a slave station of EtherCAT, humanoid robot joint completes communication control through the master controller. However, there are many problems in the process of master-slave communication such as frame loss and delay. The EtherCAT-Analyzer of Zhiyuan Electronics has the functions of network frame statistics (flow, forward delay, error frame and periodic jitter), network frame time analysis, network content analysis, GPIO event analysis and frame data storage, which can quickly analyze and evaluate the network state of humanoid robots and help solve problems.
Main functions
Wireshark analysis protocol, locating the master-slave communication problem
The upper computer is connected to the EtherCAT analyzer. The software maps the virtual network interface card. You can easily check the master-slave initialization interaction information, get the configuration parameters of the slave station, master the protocol differences of various manufacturers, and solve the adaptation problem. You can also use the real-time topology to determine whether it is a problem such as “frame loss of device”, “the device does not process data”, and “the device is disconnected”.

Support GPIO event capturing, and meet the requirement of network synchronization analysis
The device supports GPIO event monitoring, captures the DC interrupt signal from the slave station, and then adjust the appropriate offset time.
<1ns forward delay, accurate evaluation of the master station cycle
EtherCAT analyzer supports the frame forwarding time analysis of 4 ports. In a multi-node EtherCAT network, it does not affect the actual communication, and it can accurately analyze the actual PDO period and jittering of the master station.
Visualized numerical curve helps easily judge the execution efficiency of slave station
EtherCAT analyzer supports intra-frame numerical curve analysis and the analysis of numerical values according to frame offset and arbitrary extension protocol, analyzes the following curves of motors and algorithms of humanoid robots, and finds out the performance bottleneck of machinery or algorithms.
Network load monitoring, real-time grasp of node frame flow
EtherCAT analyzer supports the network load analysis of specified data sources. It also supports filter setting, which can analyze the frame flow for a PDO.
Trigger for saving, data playback
The upper compute configures a triggering condition. When the corresponding conditions are met, the upper computer will automatically save the relevant data to the relevant paths. After that, the saved data can be replayed and analyzed by the upper computer.
The intelligent upgrading of the system can be realized quickly with the ZWS IoT cloud platform
The ZWS IoT cloud platform independently developed by Zhiyuan Electronics can help your system realize intelligent upgrading and support remote firmware upgrading, quick recall of log files, business data monitoring, configuration visual presentation, massive data analysis, etc.
