A lightweight robotic arm with a footprint smaller than A4
Thanks to its compact design, the MG400 aka Magician Pro, fits perfectly and is easy to install on desktop production line systems. With a total weight of 8kg and a maximum load capacity of 750g combined with a maximum working radius of 440mm, it is the master of desktop work.

Its accuracy of 0.05mm is industrial grade, making it suitable for precision tasks such as sampling in research work or assembly tasks on small, complex systems.
Its footprint is 190x190mm, so finding the right space for the robot arm is no challenge.
Industrial performance Thanks to its vibration damping algorithm. The stabilisation time is 60% faster and the residual vibration 70% lower compared to the rest of the Magician range, also for desktop robotic arms.
4 axes, 4 movement modes
The robot arm can move from point A to point B by connecting two coordinate points in 4 modes:
Joint Interpolated Motion: The movement can be implemented with GO and MoveJ, thanks to which the robot arm interpolates the position of the end tool from point A to point B without taking into account the position of the end tool.
Linearly Interpolated Motion: The movement can be implemented using a Move program, which thanks to the robot, connects the coordinates of point A and point B by checking the position of the sky, which guides the end tool straight through. In the case of linear motion, a distinction can be made between the use of the jump mode, where the end tool either moves the two coordinate points to their end positions, or applies a rounding off to perform a continuous motion, taking the coordinates of the point into account.
ARC -Circular Interpolated Motion: The robot connects points A and B along an arc with the help of an auxiliary point C, thus performing an arc movement taking into account the position of the end tool.
Circle - Circular Interpolated Motion: Connecting points A and B by means of an auxiliary point C, the robot moves in a circular path, taking into account the position of the end tool.
Simplicity in all its characteristics
Unlike the CR series of industrial performance robotic arms, the MG400 contains both the control unit and the robotic arm in a single unit, making its design much more compact than its industrial performance counterparts.
It can be programmed in several ways. These include:
Reproduction of end tool movements: A related programming method is Teach & Playback programming, a way of programming robot arms that does not require programming knowledge to set the parameters of a task. The programmer can freely move the robot arm by pressing and holding a safety lock release button, and then release the button to stabilize the arm in the given position. In the programming interface, these coordinates can be viewed and stored as a coordinate point that the robot arm must touch during the execution of a task. By saving the points, you can then move the robot arm without any programming skills.
Blockly programming (Drag and Drop): Also known as graphical programming, it makes it easier to learn programming by visualising functions, variables and modes of operation. Its working principle is based on the interconnection of blocks, i.e. the blocks representing each function are connected in series to program the robot arm.
LUA and Python Script: With its easy-to-understand syntax and large library, it can be used to program many robotic automation processes.
DobotStudio Pro, the development environment for the robot arm, comes with the libraries needed to control the robot arm by default, so all you have to do is review the documentation and create your own LUA or Python program to run your robot arm.
Coordinate Systems
The coordinate system of the robotic arm system is divided into four coordinate systems:
Base coordinate system: The base coordinate system determines the coordinates, position and motion of the end tool, based on the base coordinate system, which is defined by the Cartesian coordinate system.
Joint coordinate system: The coordinate system of the joints is determined by the possible movements of each joint.
End-tool coordinate system: A coordinate system defining the offset distance and rotation angle, whose origin and orientations vary depending on the position of the workpiece on the robot base.
User coordinate system: A movable coordinate system used to represent equipment such as fixtures, workbenches. The orientation of the origin and axes can be determined based on site requirements, to measure point data within the workspace and to conveniently arrange tasks.
WIDE RANGE OF ACCESSORIES AND END TOOLS
Compatible with a wide range of end tools and accessories, it will meet even the most specific business needs. It is compatible with vacuum (vacuum source required) and electrically powered grippers, conveyor accessories, linear slide rail accessories, image processing units, and Modbus and PLC accessories for communication.
A universal accessory is the Cobot Universal Training Platform , which includes a range of accessories and applications for the MG400.
