Im working on adding force sensitivity to the gai tof my hexapod. Ive chosen a very simple aproch to this. Simply added 0.1 ohm resistors between servos and ground, using analog MUX and intenral A/D of the 18F452 to measure the current passing thru each servo. This is not going to be very acurate, but hopefully it will be sufficent for what i need.
In addition to this it is nesesary to monitor the real pitch and roll of the robot. One way is ofcourse to use a 2 axis accelrometer and integrate on it to get the tilt . What i would prefer is some kind of module that has this built into it. Ive read alitle about electrolyte tilt sensors. To my understanding its basicly a electrolyte capasitor that has its capasitance changed by beeing tilted (the electrolyte flows between the condensator plates).
Does anyone know of any prebuilt modules, IC's or any other inteligent way to go about solving this problem?
