Week 09 - Input devices

This week I focused a lot on force measurement, that might be of importance for my final project. In case of I decide to go with the angular measurement, I also tried an gyroscpe/accelerometer.

Summing up the results from week 9 I got the following results / findings:

• Strain gauges can be made in a Fab Lab, but not for very reliable / sensitive applications and FR1 stock seem to have poor fatigue behaviour.
• Load cells seem to be convenient to work with, but the ones I found and used aren´t sensitive enough
• I need to experiment more on applying and using strain gauges and how to prevent kreeping and unwanted tension / stress. Also I need to consider more the DoF and constraints of my design.
• It might be more difficult then expected, to make a reliable strain gauge force measurement in 2-axis.
