Texture Analysis in action: the Bread V Squeeze Rig

Loaf freshness test using the TA.XTplus Texture AnalyserThe BREAD V SQUEEZE RIG (A/BSR†) enables testing of the softness and springiness of both packaged and unpackaged loaves, thereby giving a good indication of freshness.

A common way to test the softness of a loaf is by squeezing it between the thumb and fingers, creating a ‘V’ shape with the hand. The rig imitates this process and allows repeatable, scientific analysis of the freshness and appeal of bread.

Testing for robotics design

Humanoid robotsA humanoid robot is being developed at the School of Engineering and Advanced Technology, Massey University, New Zealand, for implementing and evaluating dynamic gait algorithms.

Force sensors are placed on the bottom of the feet of the robot to provide feedback for the control system. The use of resistive force sensors is being investigated as an inexpensive and lightweight alternative to multi-axis force/torque sensors. 

However, resistive force sensors have a more limited accuracy and response time. Sensors from three companies have been tested: Sensitronic, Interlink, and Inaba Rubber.
