Hydraulic quick couplers are the least expensive component on very expensive equipment yet are often not considered until failure occurs. With high expectations for long hours and meeting productivity goals, be sure to include checking your hydraulic quick coupler performance to the checklist. It’s that time of year that we see tractors busy in the fields, Bobcats® hurriedly moving about construction sites and skid steer utility vehicles of all types busy at work. yaw = %f", degrees(attitude.roll), degrees(attitude.pitch), degrees(attitude.Get your equipment ready for Spring with leak-free skid steer flat face couplers that facilitate smooth operation for a busy workload. The remaining code #define degrees(x) (180.0 * x / M_PI)ĬMDeviceMotion *motion = viceMotion Īttitude = %f. viceMotionUpdateInterval = 1.0/60.0 //60 Hz So, if I am using the default attitude reference, the iPhone considers that the face up resting position is the default and the blue axis (yaw) will always be the vertical one. The only explanation I have for this is, the gyroscope axis don't rotate when you rotate the device. If I am rotating the device anti-clockwise (positive) on X, I should see an increase on the pitch angle, not yaw. If the iPhone is resting on its left side on the table, the green axis (pitch) is vertical. On the iPhone, that would mean a pitch rotation, but as I rotate, pitch remains constant and YAW is the one that changes!!!!! Then I start to rotate the iPhone according to the table's vertical axis in an anti-clockwise fashion, that would be on the positive direction according to the table vertical axis. When I put the iphone on a table resting on its left side (home button on the right), perfectly at 90 degrees in relation to the table plane, these are the values I read for roll, pitch and yaw: -90, 0, 0. According to the picture below and as far as I know, roll, pitch and yaw correspond to the red, green and blue axis, right? I have a very simple application where I am trying to use the gyroscope thru core motion.Īt this point, for test purposes, I am just grabbing the values of roll, pitch and yaw and printing on screen.
