Vex Gyro Sensor Programming

Among other things the gyro allows your robot to make very precise consistent turns.

Vex gyro sensor programming.

Vex and vex robotics are trademarks or service marks of innovation first international inc. Gyro sensors are used to measure movement in some handheld electronic devices such as video game remote controls. A gyro turning clockwise will decrease its values. The front facing eye sensor also acts like a distance sensor and returns the distance of a detected object in mm and inches.

Autonomous programming line by line 7. Gyro sensors are used to stabilize large ships as well as monorail trains in order to keep the people and cargo on them safe. Some common uses for a gyro sensor with a vex iq robot include. Use the gyro to make precise measured turns.

The vex iq gyro sensor uses a texas instruments msp430 microcontroller running at 16 mhz to process requests and calculate angles. This code will also be compatible with the new vexcode programming suite vex is developing. Use the gyro sensor and the pen to draw a triangle with the vr robot. Driver control programming part 2 6.

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. Draw a triangle with gyro. Other sensors like the shaft encoders allow you to control your robot s turns but indirectly. They will make you physics.

Autonomous programming functions 8. The msp430 communicates with the latest mems gyroscope across a very high speed 10 mhz spi bus. Lectures by walter lewin. Direction can be determined by positive and negative values.

For the love of physics walter lewin may 16 2011 duration. Check that smart ports 1 12 have the correct types of devices listed in the table above. If the program does not find smart motors or bumper switches it will check for the devices listed in the table. Program the vr robot to move forward and reverse to various distances.

Detecting if the robot has turned left. A gyro turning counter clockwise will increase its values. Motor encoders that are 360 degrees per wheel revolution. Sensor programming part 2 10.

Sensor programming part 1 9. The vr robot has the following sensors. We ll use the ultrasonic distance sensor to measure distance and make the robot react to obstacles. The mems gyro measures rotation rate with 16 bit resolution.

Use the infrared line trackers to follow lines or stop on marks lines on the floor. A gyro sensor that is built into the drivetrain.
