It can be challenging to find the right robotic arm for your automation assembly needs, so it is essential to reach out to professionals early in the design phase of creating systems. Deciding on the type of arm is necessary for an optimal design and construction process. When making consideration regarding robotic arms, you must pay close attention to factors such as available floor space, cycle time requirements, safety, and programming skills.
Below, we want to briefly go over the three most popular types of robot arms. Learning about the differences between these units helps to make deciding on a robot arm much simpler.
Small Industrial Robot: this system has six degrees of freedom, which means that they can move in 3 planes, pitch, make rolls, and yaw movements. If you need an automated assembly machine that can handle complex actions (like a human arm), you should consider this type of arm.
It is best suited for specific applications that include:
- Picking and placing parts at specific angles
- Low mix production that has infrequent part changeovers
- Working with larger safety scanners
Collaborative Robot: these systems have six-axis that are great for working closely with humans. They are constructed with sensing technology that causes them to stop when an obstacle is detected automatically.
Scara Robot: this 4-axis robot is commonly used for operations where high speed and high accuracy are an absolute requirement. It is best suited for:
- Picking pieces from flat surfaces
- High accuracy and repeatability
- Short cycle times
- Low mix production
