Uniaxial Steadicam

Overview Make a uniaxial Steadicam with motor module and motion module, and control the motor to spin through leaning the platform right or left. Module List Module Module Number Function mCookie-Core 1 Core board Battery box 1 Program download and power supply mCookie-Hub 1 Sensor adapter plate Servo 1 Servo Servo Connector 1 Servo connector Motion module 1 Detect motion, equivalent to a gyroscope Other Equipment USB cable*1 Building blocks or other fixation structures Module Setup Setup Assemble modules and sensors together: Connect the servo to pin 6/7 of Hub through servo connector, note that connect it to the lower pins of the connector; Stick the red core module, green Hub and yellow motion module to the yellow battery base; Plug one end of the USB cable into the battery base and connect the other to the computer; Programming Programming Thought Pitch: when the X axis arrow points to the horizontal direction, the pitch degree is 0; when it points to left horizontally, the pitch degree is 0; when it points to top vertically, the pitch degree is 90; when it points to bottom, the pitch degree is -90. When the base of the platform is level, the servo should be kept at 90 degrees, at this moment, the pitch degree is about 0 degree. When the base leans up (the arrow of X axis of the motion module points to top), the pitch degree is between 0-90, the degree of the servo is the sum of 90 degrees and the pitch degree. The degree of the servo is between 90-180. When the platform leans downward (the arrow of X axis of the motion module points downward), the pitch degree is between 0-90 degrees, the degree of the servo is the sum of 90 degrees and the pitch degree. The degree of the servo is between 90-0. Required Program Blocks “Motion DMP solution” program block “Get motion degree” program block “Calculate” program block “Servo” program block Start to Program Motion DMP solution, the degree of pin 6 servo is the sum of pitch degree +60 Test the result After powering on, keep the motion module level for 5s, lean the platform at pitch direction, and the servo can make the platform level always. Q: If the motion sensor is stuck to the other end of the battery base, what will happen? A: Under that situation, the pitch degree of the motion module is just opposite to the original one, you can change the 90+pitch degree in the code into 90-pitch degree. Send the pitch degree to the serial monitor Technical Specification For more about motion module, please refer to: Motion Module For more about servo, please refer to Servo Relative Cases Revolution Indicator Body Sensation Biaxial Steadicam FAQ
