Version Description:
Version Description V 1.7.5
Version Change Description
Algorithms & Motion Control
Added safety validation for force-controlled dragging: Introduced state detection when enabling force-controlled drag teaching. If the initial force on the sensor exceeds the safe range (safe range: force < ±4N, torque < ±0.14 N·m), the system will automatically pop up a prompt to perform zero calibration, ensuring the safety of the initial teaching operation. For details, refer to Force Control Dragging Safety Check.
Improved trajectory planning stability: Fixed false alarm issues during trajectory planning task execution caused by frequent pause/resume operations, avoiding abnormal errors such as "unreachable" and "joint overspeed".
Enhanced singular pose detection: Synchronized the singular pose detection cycle precisely to 4 ms, improving real-time monitoring capability for singularities in complex motion paths of the robotic arm.
Hardware Adaptation & System Integration
Added support for vision-integrated arm series: Fully supports RM65-V and RM75-V models, including both standard versions and versions equipped with six-axis force sensors, enhancing vision-integrated capabilities.
New model support:
Added support for the RX75 humanoid robotic arm series. For details, refer to RX75 Series Parameters.
Added support for the ECO62-B configuration robotic arm (Note: this configuration does not support ecosystem protocols). For details, refer to ECO62-B Series Parameters.
Adjusted joint limits: Unifiedly adjust the default hard limit range of RM75 (Axis 5), RM65 (Axis 4), RML63II (Axis 5), and ECO63/ECO65 (Axis 4/5) to -183° ~ 183°, effectively expanding the motion range and working envelope of the robotic arm.
Enhanced WiFi module stability:
WiFi module is disabled by default (V1.7.5 and later versions default to disabled, previous versions default to WIFI AP), and exception handling is added during initialization to prevent abnormal WiFi interference with the main control program.
Optimized network scanning logic to automatically filter invalid signals with channel 0, improving network detection accuracy.
System Optimization & Reliability Improvement
Optimized firmware upgrade process: Improved the upgrade logic for controller, joints, and end-effector firmware. Supports batch continuous uploads and step-by-step orderly upgrades, requiring only a single controller restart throughout the process, significantly reducing maintenance time.
Enhanced power-on safety monitoring: Added controller mainboard current monitoring during the soft-start phase to strengthen protection against overcurrent and abnormal power usage.
Optimized communication transmission mechanism: Improved the reporting logic for communication frame loss, enhancing the real-time performance and accuracy of data transmission status monitoring.
Bug Fixes
Optimized ecosystem devices and haptic feedback
Fixed the issue where haptic data was not synchronized after enabling the end-effector ecosystem protocol on the teaching pendant, and improved the logic of haptic switch control to ensure state consistency.
Added an HTTP API for querying the haptic switch status, resolving the issue of switch state reset caused by page refresh.
Optimized programming and trajectory interaction
Fixed abnormal speed changes caused by triggering trajectory replay during graphical programming execution.
Addressed logic flaws where switching loop tasks could instantly trigger trajectory replay, causing abnormal program termination.
Optimized UI and functional interfaces
Coordinate System Management: Fixed a UI issue where list content was truncated when a coordinate system was named NULL; resolved the issue where end-effector payload limit rules did not take effect during tool frame editing.
Search Function: Improved point search rules and fixed compatibility issues where special characters (% and _) could not be recognized.
Optimized API commands:
Fixed the issue where the device runtime state could not be synchronized after current-loop drag teaching was interrupted by API commands.
Improved JSON command exception handling to eliminate the need for manual Enter key input to clear the cache after parsing errors.

After the soft limit is modified, the teach motion will be restricted based on the newly set boundaries.
Fix the issue where the JSON command "Start running the specified online programming file by number" and the "Run" button in the teach pendant's data management—graphical programming file list fail to properly execute graphical programming files with names containing a mix of Chinese characters and special characters.

V 1.6.7
Version Change Description
High-Follow-Through Transparency Function Optimization: In high-follow-through transparency scenarios, three modes are supported.
- Mode 1: Full Transparency Mode, this is the default mode, which directly passes the original data to the joints, and the joints fully support the trajectory sent;
- Mode 2: Curve Fitting Mode, in this mode, a smoothing coefficient (0-100) can be input, the larger the smoothing coefficient, the smoother the trajectory; however, the lag effect will be more noticeable, with a maximum lag of about 15 cycles;
- Mode 3: Filtering Mode, in this mode, users can input filtering parameters (ranging from 0 to 1000). The larger the parameter value, the smoother the motion trajectory of the robotic arm will be. Since filtering technology is used, after the user inputs the last target point, to ensure that the robotic arm can accurately reach the target position, the user needs to continue sending instructions for the last target point until it is confirmed that the robotic arm has reached the final position.
Top Navigation Bar Optimization: The speed bar displays or sets the current speed of the robotic arm in real-time.
Graphical Programming Optimization: Adds real-time speed adjustment blocks to the basic category.
External Interface Optimization: IO control adds real-time speed adjustment options.
Real-Time Speed Adjustment Function and Interface: Real-time control of the robotic arm's movement speed can be achieved through the teach pendant, IO, Modbus, and online programming.
Joint Enable Error Optimization: Optimizes the situation where, when the joint drops enable, sending errors and sending motion control commands (MOVEJ, MOVEL, MOVEC, MOVEJ_P, MOVES, etc.) do not return failures.
Support for Real Mode: Electronic fences and self-collision support real mode.
3D Model Supports Copying Position Information: In the pose information area of the 3D model, supports right-clicking to copy position information, and users can choose to copy joint information or pose information.
Online Programming File Export and Import Optimization: Online programming files support one-click batch export and import.
Graphical Programming Optimization:
- Adds a modification time field, supporting viewing in ascending or descending order by modification time.
- Prompts the line number when stopped, and the click on that line or rerun makes the indicator disappear.
Modbus Optimization:
- Add an emergency stop status to the input register addresses: The emergency stop status is triggered by an emergency stop operation and directly cleared upon release.
- Adds start address inquiry.
- Adds data format switching for controller 485 and end 485, including unsigned numbers, signed numbers, and hexadecimal numbers.
JSON Protocol Reply Optimization: Elevator control supports immediate JSON protocol response, with a follow-up response indicating the status of arrival once the position is reached.
