When trying to bring a robot arm into a laboratory, people often worry, “Which model would actually fit our experiments well?”

In this post, we are going to compare two popular collaborative robots for research: the 7-axis MAiRA (NEURA Robotics) and the 6-axis myCobot 280 (Elephant Robotics). 

By looking at the features of each robot, we will help you make a smart choice on which robot is suitable for which situation.

This post is structured as follows: 👇

▪ Difference between 6-axis and 7-axis collaborative robots

▪ Identifying core differences: "MAiRA vs. myCobot"

▪ Recommendations by research type (AI experiments / Prototyping / Educational practice)

▪ Information on Marosol Special Exhibition benefits

After reading this post to the end, the picture in your head of why your lab really needs to introduce a robot arm, and which of the two models should be reviewed first, will become much clearer. 🙌

Difference between 6-axis vs. 7-axis Collaborative Robots: What is Different?

First, let’s go over the concept of axes (Degrees of Freedom). The axes (joints) of a robot arm mean the degrees of freedom it can move. A typical industrial robot arm has a 6-axis structure, possessing 6 joints like a human shoulder-elbow-wrist, allowing it to position and rotate its fingertip in any direction in space. 

Since 6-axis robots provide sufficient flexibility for most tasks, they have been used as a standard in industry and research for a long time.

Then, what is different about a 7-axis robot (7-DOF Robotics Arm)? 

By having a 7th axis, additional freedom of movement is created in the robot arm. For example, a human arm also has extra joints at the shoulder and elbow, so it can work by twisting the arm even in narrow spaces. Similarly, a 7-axis robot can work by changing postures more flexibly in cramped spaces and can manipulate tools in various directions even when approaching very close to a workpiece. 

As a result, 7-axis robots utilize workspace more efficiently than 6-axis robots and can show more flexible motions like a human arm.

In summary, a 6-axis robot is already sufficiently capable for various tasks, but a 7-axis robot can be called an even more talented arm. Due to the additional axis, options for intermediate postures increase, dead zones at specific positions are resolved, and it allows for relaxed handling of complex tasks. Therefore, if precise and complex motions or work in limited spaces are required depending on the research purpose, the advantages of a 7-axis robot (7-DOF Robotics Arm) will be significant.

 NEURA Robotics' 7-axis Collaborative MAiRA

MAiRA is a 7-axis collaborative robot made by the German company NEURA Robotics. This robot is introduced as the world's first commercialized cognitive robot, characterized by being an AI-based robot arm that recognizes surroundings like a person, learns, and adapts on its own. 

MAiRA has built-in advanced machine vision (3D camera), spatial acoustic sensors (360° microphone), and a high-performance AI processor, so it operates as if a robot research platform and an AI assistant are combined.
