Although the new servo had worked with the adxl345 sensor, it still contains some risks, that is the noise from different direction. This means that because the adxl345 is based on the X,Y,Z, so when you rotate the sensor not competely in one direction, the noise from other direction movement will influence the transmission of the signal. Leading to the fact that the servo will receive the inaccuracy order, and shaking for few seconds, this makes me very struggle and hard to fix.


The testing of adxl345’s noise influence

Then I discussed with Gareth again, he suggested me to use the stretching rubber sensor to do the test. Due to the good extensibility of it, it is easier to drive my physical feet platform. However,unfortunately, the stretching sensor also work along with some noise, influence the rotating of the servo, even more worse than the adxl345.

The reasons why the stretching sensor along with more noise,  after many times tseting, I found it is because Static electricity of our body or the air make the sensor instable.
