I have an MX-64 servo which I am using to rotate an accelerometer. I am comparing the angle according to the servo with the angle I measure using the accelerations from my accelerometer. I am testing the system described in a thermal chamber ranging from -20C to 50C.
My question is this:
Does the accuracy of the servo position and or angular velocity vary much within this range?
Also, the servos temperature sensor provides wildly inaccurate readings. Is this always the case?
I realise the servo is not specified below -10C but the temperature sensor appears to only go as low as 10C.
The Dynamixel MX-64 running temperature should be in this range -5°C ~ + 80°C. In the normal conditions, the position sensor should have a resolution of 360 ° / 4096 equivalent to a resolution of 0.088° ( 12bits, 360 degree encoder ). So the accuracy of the servo’s position shouldn’t vary much in -5°C ~ + 50°C range. However, if you’re using the servo at a temperature below than -5°C, let’s say -10°C, the temperature sensor can provide inaccurate values.
You might need to verify the MX-64’s resolution, to confirm that you’re not using the Resolution Divider or the Multi Turn Offset to obtain the Real Position.
