High-Payload Benchtop Robotic Arm with Multi-Interface Connectivity Engineered for Advanced Automation Labs and Applied Technical Education
The ZKBOT-303ed is an advanced 3-axis intelligent interactive desktop robotic arm engineered for technical universities, vocational colleges, and engineering innovation centers. Featuring 3 degrees of freedom (3-DOF) and an upgraded 1.0 kg payload capacity, it overcomes the payload constraints typical of desktop educational manipulators. Built with NEMA 17 stepper motors, precision spur gearboxes, and an integrated power-off holding brake on Axis 2, the system supports dual-mode operation via an onboard touchscreen teach pendant and PC host software. Pre-configured with Point-to-Point (PTP), linear interpolation, linear offset, and palletizing algorithms, alongside standard industrial 24V 6DI / 6DO interfaces and wireless connectivity, the ZKBOT-303ed serves as a complete hardware platform for multi-axis robotics kinematics, multi-channel PLC integration, machine vision sorting, and automated path plotting.
Upgraded 1.0 kg Rated Payload: Capable of handling a wide variety of functional end-of-arm tooling (EOAT)—including mechanical grippers, pneumatic vacuum suction arrays, precision plotting pens, and machine vision sensors—to accommodate diverse laboratory curriculums.
Axis 2 Electromagnetic Holding Brake: Equipped with an electromechanical power-off holding brake on the shoulder joint. In the event of sudden power loss or emergency stop, the mechanical link is instantly locked to prevent gravitational dropping, protecting tabletop equipment, end-effectors, and workpieces.
Intuitive Dual-Mode Operation: Outfitted with a 4-inch serial touchscreen teach pendant for responsive manual jogging and point teaching, while fully supporting PC host software for advanced visual trajectory programming, script simulation, and instructor demonstrations.
Dual Coordinate System & Built-in Kinematics: Enables on-the-fly switching between Joint Coordinate and World (Cartesian) Coordinate spaces, supported by built-in motion planning algorithms including Point-to-Point (PTP), continuous linear interpolation, path offsetting, and structured 3D matrix palletizing.
Industrial 24V 6DI / 6DO Interface: Features a dedicated 24V/0V digital logic interface (6 inputs / 6 outputs) alongside USB serial and Bluetooth interfaces. Enables direct multi-signal interfacing, recipe selection, and interlock handshaking with external sensors, conveyors, and mainstream industrial PLCs (including Siemens, Mitsubishi, and Omron controllers).
Plug-and-Play Benchtop Deployment: Weighing just 6.0 kg with an ultra-low operating power consumption of 50 W, the unit supports both desktop and floor mounting, allowing rapid, space-efficient deployment across multi-workstation teaching laboratories.

Engineered for advanced laboratory curriculums in Robotics Engineering, Mechatronics, Electrical Automation, and Smart Manufacturing Systems. Serves as a direct physical validation platform bridging theoretical kinematics and multi-axis trajectory control.
Leverages a multi-channel 24V 6DI / 6DO industrial interface to execute coordinated sequence control, signal handshaking, and hardware interlocking with external industrial PLCs (e.g., Siemens S7-1200, Mitsubishi FX Series, Omron).
Functions as a standardized desktop execution unit for collegiate maker contests, automated trajectory plotting, chess-playing simulation, and multi-station conveyor sorting and palletizing challenges.
Supports external machine vision modules and open-source frameworks for computer vision research, covering 2.5D planar workpiece localization, dynamic QR-code scanning, and automated color/shape sorting workflows.
Explores forward and inverse kinematics using the dedicated teach pendant and PC host software. Students conduct hands-on experiments switching between Joint and Cartesian (World) coordinate spaces, analyzing kinematic singularities, and verifying multi-point spatial trajectory planning.
Focuses on advanced industrial hardware interlocking using the 24V 6DI / 6DO interface. Enables multi-bit binary signal interaction with external PLCs (e.g., Siemens S7-1200, Mitsubishi FX), allowing students to implement automated job selection, sensor interlocks, real-time status telemetry, and emergency fault handling.
Utilizes proprietary linear interpolation and dedicated palletizing algorithms to execute precision 2D planar vector path drawing, contour following, and multi-tier 3D array stacking. Demonstrates industrial packaging and material handling logic without complex manual point programming.
Combines external optical cameras with PC/Bluetooth host interfaces to build end-to-end computer vision workflows. Students apply image processing algorithms for color extraction and geometric shape recognition, driving the robotic arm to execute 2.5D planar localization and automated sorting tasks.
