iNexBot's Product Strategy: Focus, Moderation

Venture into the general motion control market

In addition to the robot market, the general motion control market holds tremendous potential. We were born for robots, but we won't stop there. The general motion control field is our vast ocean.

Establish an open-source community

We will build iNexBot open-source libraries in open-source communities such as Github and Gitee, and actively embrace open-source.

Organize regular nationwide training events

We will conduct training activities nationwide to help users understand and fall in love with the iNexBot control system.

Improve quality and conquer users with excellent quality

We will enhance software quality and ensure zero critical bugs in product delivery. At the same time, we will conduct hardware tests such as CE for all hardware products to ensure their hardware stability. Starting from 2024, we will initiate functional safety certification IEC 61508.

Build a strong research and development team for motion control

We will expand the team from 120 to 200 members, with technical personnel accounting for no less than 80%.

Optimize motion control algorithms

We will continue to optimize motion control algorithms benchmarking against top international control systems like Beckhoff and KEBA.

Vision and control integrated technology

The integration of 2D/3D/laser technology with robots enables them to have perception capabilities.

Drive and control integrated technology

Drive and control integration is the inevitable path towards high performance, and the threshold for drive technology will be significantly lowered.

Mobile and collaborative robots

iNexBot will independently develop navigation, scheduling, and motion control algorithms for collaborative robots.

IDE platform construction

iNexBot's NexDroid Studio IDE platform will provide device management, programming, and simulation functionalities, and integrate Copilot's AI program generation capabilities.

Preview

NexDroid Studio includes robot management tools, programming environment, debugging tools, secondary development platform, and industrial Internet platform. It provides local and remote job program file management, and integrates Lua, JBR, and other language servers to offer efficient functions such as syntax and lexical parsing, code completion, and highlighting. Additionally, it integrates Copilot's AI-based code generation services. To facilitate the use of debugging personnel, NexDroid Studio integrates oscilloscopes, command lines, remote file management, ENI editing, virtual simulation, and other debugging tools.

Industrial Internet platform

iNexBot's industrial Internet platform provides capabilities such as industrial data management, AI training, predictive maintenance, and production process improvement. NexDroid Studio industrial Internet platform can back up local control data and running programs to the cloud and deploy them to networked controllers. The digital twin system can faithfully reproduce the operating status of physical devices. With the help of powerful cloud servers, developers can add operators to analyze cloud-based data and use the analysis results to raise alerts for abnormal conditions.

NexDroid 2.0

The target area of NexDroid 2.0 is the robot and general motion control market. The product includes brand-new hardwares, algorithms, IDE platforms, vision and control integrated technology and AI capabilities.

Algorithm optimization

Optimized interpolation, smooth transition, and small line segment algorithms.

• Added smooth transition types: time-based transitions and distance-based transitions.
• Adopted new smoothing algorithms to ensure G3 continuity of curves.
• Based on smooth transitions, a constraint model is established that includes trajectory error constraints, velocity constraints, acceleration constraints, and jerk constraints. Within the constraint model, small line segment trajectory lookahead is conducted to improve operational efficiency.

Singularity avoidance: pass through singular points slowly

• Mathematical expression: The singular pose of the robot arm implies that the Jacobian matrix is no longer full rank.
• Algorithmic behavior: The existence of infinite solutions leads to attempts to achieve large instantaneous rotations for J4 and J6.
• Solution: Detect the position of singular points in advance, limit joint speeds, and pass through the singular point-related area slowly.

Controller hardware enhancement

NexDroid 2.0 comes with the new controllers C1200 and C1201. The CPU has been upgraded from J1900 to J6412, resulting in a 3x improvement in overall computational performance. It now supports up to 64 axes of simultaneous motion, compared to the previous 24 axes. The multi-port design simplifies the wiring in industrial settings, replacing the previous industrial switch solution by unifying the interfaces for devices such as cameras and PLCs. The inclusion of a supercapacitor UPS module effectively addresses hardware damage and data loss caused by unauthorized power outages in industrial scenarios. It also provides data recovery functionality, allowing the resumption of operation logic prior to the power outage to ensure continuous production on-site. C1201 is also equipped with versatile peripheral interfaces, featuring an X86+FPGA structure to ensure high-speed IO output. Furthermore, the configuration of PWM/CAN interfaces enables C1201 to be applied in more complex process scenarios such as laser welding and cutting.
