In-house production equipment is easier to build than you think. Here's an example of a 5-axis SCARA robot.
Overview
This is an in-house SCARA robot that automates work pick-and-place and transport between processes. It is used in automated production lines for gluing, measuring, and assembly, which were conventionally done manually. We built a SCARA robot in-house because we needed to realize pick-and-place and transport between processes in a limited space.

No ladder logic knowledge required.
Easy introduction of in-house robots into existing systemsLinkage between MRC01 and host system is directly controlled by EtherNet/IP. In-house robots can be easily added without making major changes to the control system of existing equipment. Easy setting even for the first timeThe MRC01 can be easily set from initial settings to operation programs without specialized knowledge of programming languages. Initial settings such as selection of robot type and input of mechanism information are easy with a wizard. Targeted commands can be added to the operation program while moving the in-house robot with teaching operations. When one of our young equipment designers actually used it for the first time, he was able to create a program by teaching in about two hours because it was possible to set multiple axes with a single command. Operation can be checked with online 3D simulationIt is possible to check the operation program of the in-house robot on the 3D simulator without driving the motor. Control of the end effector axis is also possibleIt supports vertical articulated robots, SCARA robots, and orthogonal robots, which are typical structures of industrial robots. The end effector axis can also be controlled by the MRC01, contributing to space-saving, wiring-saving, and cost reduction for the entire system. Compatible with a wide range of lineupsCompatible with AZ series and electric actuators equipped with them. With a rich product lineup, we contribute to robot design with a high degree of freedom according to the robot type you want to manufacture in-house.

All of the motors, actuators, and drivers controlled by the MRC01 robot controller on the SCARA robot are from the αSTEP AZ Series family.
Products equipped with αSTEP AZ series
Achieving sensor reduction and battery-less with a mechanical multi-rotation absolute sensor
With the αSTEP AZ Series technology, external sensors such as the home position can be reduced, contributing to reduced wiring and a compact configuration. Since the mechanical multi-rotation absolute sensor <ABZO sensor> is used, absolute position information is retained even if the power supply is shut off due to an emergency stop or power failure during positioning operation. Since it is mechanical by nature, no battery is required for data retention. There is no need to worry about battery purchase costs, operational troubles, or maintenance intervals. In addition, the AZ series motor itself can be used as a sensor to monitor the robot's status numerically.
● DGⅡ Series Hollow Rotary Actuator (Axis 1, Axis 2)
Suitable for joint shaft Hollow rotary actuator and small geared type
When the SCARA robot grabs a workpiece at the tip of the arm away from axis 1, a large load moment is generated.
The DGII series uses cross-roller bearings for the hollow output table bearings to achieve a high allowable moment. This contributes to expanding the range of motion of the arm. In addition, hollow holes (through holes) can be used for wiring complicated cables, simplifying robot design.

● αSTEP AZ Series Harmonic Geared Type (Axis 3)
Geared stepper motor with no backlash
Even a small deviation can become large at the tip of the arm, and it may not be possible to grip the workpiece accurately. The harmonic geared type has no backlash, so it suppresses misalignment and achieves accurate operation.
● DR Series Compact Cylinder (Axis 4)
Compact and lightweight actuator that reduces the load on the tip of the robot mechanism
The compact body that integrates the αSTEP AZ series and a ball screw contributes to the miniaturization and space-saving of equipment. By reducing the weight of the tip of the device, you can expect to improve the degree of freedom in design.
● EH Series Compact Gripper (Axis 5)
Grip small parts delicately
As the end effector becomes smaller and lighter, the burden on each joint can be reduced, contributing to the size reduction and cost reduction of the entire robot. The position, gripping time, and gripping force can be freely set with the electric gripper. Various grips can be achieved.
