RoHaC - Robot Haptic Checker 

A measuring unit for haptic tests.

The haptic perception of operating elements is becoming more and more important. Whether their operation feels pleasant can influence a purchase decision.

RoHaC consists of a tactile gripper that is attached to the robot arm, with sophisticated and powerful software in the background.

Technical data of the measuring application

Hardware 

• Low weight under 2kg - ideal for small robots.
• Very compact design.
• Test force adjustable - adaptation to the current test part.
• Measuring resolution:
  -force transducer < 50N.
  -Absolute travel up to 1µm depending on the encoder.
  -approx. 30N peak force on linear motor.
• Maximum test force, force measuring range and stroke deflection variable. Linear or spindle motor.
• Simultaneous assignment of force to displacement, extremely high reproducibility of the measuring curve.
• Reliable detection of haptics, quality assessment of hysteresis and friction within the actuator.

Software

• Database connection.
• Measurement data export in .csv format.
• Decentralized control of robot and measuring unit via TCP/IP - therefore very universal connection to different systems.
• Graphical force-displacement display (zoomable).
