Vex Gyro Sensor Programming

Other sensors like the shaft encoders allow you to control your robot s turns but indirectly.

Vex gyro sensor programming.

Check that smart ports 1 12 have the correct types of devices listed in the table above. A gyro turning clockwise will decrease its values. Detecting if the robot has turned left. The mems gyro measures rotation rate with 16 bit resolution.

Direction can be determined by positive and negative values. Vex and vex robotics are trademarks or service marks of innovation first international inc. Sensor programming part 1 9. Autonomous programming line by line 7.

The msp430 communicates with the latest mems gyroscope across a very high speed 10 mhz spi bus. Draw a triangle with gyro. The front facing eye sensor also acts like a distance sensor and returns the distance of a detected object in mm and inches. The vr robot has the following sensors.

Use the gyro sensor and the pen to draw a triangle with the vr robot. Use the gyro to make precise measured turns. Gyro sensors are used to stabilize large ships as well as monorail trains in order to keep the people and cargo on them safe. Among other things the gyro allows your robot to make very precise consistent turns.

Some common uses for a gyro sensor with a vex iq robot include. Sensor programming part 2 10. Returns the accumulated value of the gyro sensor plugged into ndeviceindex in degrees. Gyro sensors are used to measure movement in some handheld electronic devices such as video game remote controls.

They will make you physics. For the love of physics walter lewin may 16 2011 duration. We ll use the ultrasonic distance sensor to measure distance and make the robot react to obstacles. The vex iq gyro sensor uses a texas instruments msp430 microcontroller running at 16 mhz to process requests and calculate angles.

Lectures by walter lewin. Program the vr robot to move forward and reverse to various distances. Motor encoders that are 360 degrees per wheel revolution. First the sensors program will check for smart motors and bumper switches configured in the smart ports listed for the driver control program.

If the program does not find smart motors or bumper switches it will check for the devices listed in the table. Use the infrared line trackers to follow lines or stop on marks lines on the floor. A gyro turning counter clockwise will increase its values. This code will also be compatible with the new vexcode programming suite vex is developing.

The new vex yaw rate gyro is one of the more sophisticated sensors in the vex robotics system but it s also one of the most useful and powerful. Driver control programming part 2 6.
