How to calculate rate of fall of self balancing robot?
For our self-balancing robot, the angular velocity along the x-axis alone is sufficient to measure the rate of fall of the robot. In the code given below, we read the gyro value about the x-axis, convert it to degrees per second and then multiply it with the loop time to obtain the change in angle.
How does an Arduino self balancing robot work?
In the steps that follow, we will see how to interface the MPU6050 with Arduino, how to measure the angle of inclination of the robot, how to use PID to make the robot stay balanced. An ultrasonic rangefinder is also added to the robot which prevents it from banging into obstacles as it wanders around.
How can I tune my self balancing robot?
The easiest way to tune a PID controller is to tune the P, I and D parameters one at a time. You can refer to Microchip’s application notes AN964 for more details. Basically, you will need to: Set I and D term to 0, and adjust P so that the robot starts to oscillate (move back and forth) about the balance position.
Who are the creators of the balancing robot?
Modeling, Simulation and Fabrication of a Balancing Robot Ye Ding1, Joshua Gafford , Mie Kunio2 1Harvard University, 2Massachusettes Institute of Technology 1 Introduction A balancing robot is a common demonstration of controls in a dynamic system.
What do you need for Arduino self balancing robot?
1. Arduino Pro Mini 2. GY-521 module with MPU-6050 3. DRV8833 Pololu motor driver 5. US-020 ultrasonic distance sensor 6. NCR18650 battery and holder 7. Pair of micro metal gear motors (N20, 6V, 200 rpm) and brackets 8. Pair of 42x19mm wheels Apart from the above, you will need some cables, berg connectors and one on/off switch.
How is a self balancing robot like a pendulum?
Let’s start with some fundamentals before getting our hands dirty. The self-balancing robot is similar to an upside down pendulum. Unlike a normal pendulum which keeps on swinging once given a nudge, this inverted pendulum cannot stay balanced on its own. It will simply fall over.
What kind of gyroscope is needed for self balancing robot?
The 3-axis gyroscope of MPU6050 measures angular rate (rotational velocity) along the three axes. For our self-balancing robot, the angular velocity along the x-axis alone is sufficient to measure the rate of fall of the robot.
