Customers include advanced manufacturing labs and technical universities. It is favored by researchers studying force-sensitive human-robot collaboration and delicate assembly processes.
Alice 4 introduces the proprietary multi-link parallel structure, which provides a dramatic increase in current sensitivity over Alice 3. This allows for superior "back-driveability" and safer physical interaction with humans.
The specialized linear actuators allow for "back-driveability," meaning the robot can feel external forces and respond with a human-touch sensitivity during tasks.
Incorporates perception systems that allow the robot to "track" and look at people or objects it is interacting with, a key signal in human social interaction.
Its multi-link parallel structure is inspired by human muscle and bone layouts, providing a range of motion and force profile that feels familiar to observers.
