dESKTOP rOBOT ARM

The AR4 robotic arm is a desktop 6-axis robot that is small, powerful and cost-effective. With an end load of 1.9kg, a 629mm arm span, and a global accuracy of 1mm, AR4 integrates the robotic arm, electrical system, and robot motion control into a single unit, and can communicate with other devices through a microUSB serial port for receiving coordinates and motion commands to perform actions, making it simple to operate and easy to get started.
It can be used in the education industry, light industry, service industry and other scenarios. Common applications include automated gripping, automated machining, mounting, welding, painting, grinding, inspection, remote TCP, etc.

Features

Solid & Durable Structure

The body of the robotic arm is composed of CNC aluminum alloy, and the shell is made of 3D printed PLA.

Open Source Control Software

Provide a set of open source robotic arm control software, which can be developed twice.

ROS System Communication

Build a complete moveit operation and control program to facilitate R&D (motion planning, obstacle avoidance, visual grasping algorithms, etc.) and applications.

Multiple Operation Modes

Programmable, teachable and joystick control of the robot arm

Complete Forward & Reverse Kinematics

Motion control is done by Teensy 4.1 board, which can be optimized according to the needs through arduino IDE.

* The electrical connector of the robotic arm is DC5.5 socket, the power supply voltage is 19.6~25.2V, the maximum current of the device is 10A, the rated current is 6A.Requirements: stable power supply, basic over-current, short-circuit, charge/discharge protection.
