A hybrid collaborative scara robot

Machine, Science & engineering

UNMET NEED

Selective Compliance Assembly Robot Arm (SCARA) robots are commonly used for repetitive and relatively complex manipulation tasks that require precision, making them superior to Cartesian robots in several ways. They offer precision, speed, ease of integration, compactness, and quick return on investment. With the addition of appropriate software, motion sensors, and safety measures, these automation robots can easily be transformed into side bots. However, due to their design, SCARA robots have limited vertical axis movement and are not truly collaborative as they are not backdrivable.

TECHNOLOGY OVERVIEW

The Robotics Laboratory at Laval University has developed an innovative SCARA-TAU robot configuration with five degrees of freedom, featuring all motors housed at the base. This design enables a very fast and efficient robot suitable for collaborative work with humans. This actuating mechanism is designed for intuitive and safe control of the end-effector.

The robot’s configuration offers several advantages:

  • Infinite end-effector rotation
  • 5 degrees of freedom controlled from the base including gripper control
  • Base-mounted motors that improve robot functionality
  • No sensors at the effector and direct drive motor resulting in excellent fluidity and backdrivability ,decreased impedance, and ease of learning for human-machine interfaces.
  • Low moving inertia that allows high speed and acceleration.

 

COMPETITIVE ADVANTAGES

  • Fully collaborative/ backdrivable
  • Low inertia/ Highly secure
  • No sensors at the effector
  • Low footprint
