DANY BOT (multipurpose robot)


Dany bot is an multipurpose robot, here i used pololu’s Zumo Robot for Arduino, v1.2 (Assembled with 75:1 HP Motors). It has the following specifications.

The Zumo robot for Arduino is an Arduino-controllable tracked robot platform that is less than 10 cm × 10 cm.
75:1 HP micro metal gear motors, which drives the robot approximately 2 feet per seconds (60 cm/s).
Six infrared reflectance sensor array mounted along the front edge of the chassis.
Integrated LSM303D 3-axis accelerometer and 3-axis magnetometer that can be used to detect impacts.
Integrated L3GD20H 3-axis gyroscope that can be used to track rotation.
7.5 V boost regulator for powering the Arduino from the Zumo’s 4 AA batteries
It also has an optional buzzer to play the sweet musics.

Here I used Arduino Uno R3 for controlling the robot. Then I planned to fix the additional components like 16x2 lcd Display, bluetooth module, distance sensors etc. since the chassis if covered by Arduino board on the top, it is slightly difficult to attach the other components above it. so I planned to make an proto shield that houses the other components.

I made this shield from an soldering board because it is much easy to cut and cheap. this board is attached the Arduino board with the help of some bolts and spacers.
Above the shield, I attached the 16X2 LCD Display, Here i used an port expander PCF 8574 to drive the LCD. It uses the I2C(Inter Integrated Circuits) serial communications. only two pins (SDA and SCL) form the Arduino is required to drive the display.


Also I attached the HC-05 bluetooth module to control and monitor the robot wirelessly. It uses the TXD and RXD pin in Arduino to for the communication.

It can be programmed as line follower, maze solver, Self balancing, wireless control, autonomous control etc.

Soon I will upload the Video.

Hello.

Thanks for sharing your robot. Those look like useful expansions. I’m looking forward to seeing the video of it.

yep.! soon i ill post the video. Thank you.

I am working on programming the dany bot to balance itself. for the i have to remove the front shield and the sensor array from the zumo chassis. so that i can balance the robot in front.



since i have attached the display, so the center of gravity to 23.8 degree. It was calculated with the help of integrated gyro on the zumo shield.




I used the PID algorithm for the better feedback and control, still it requires tuning of the PID and other constants. it has high oscillation and error, testing is going on to improve the stability

Soon i will upload the video with better control and high stable.

Whoa… Such a great job! As I see, I have a lot to learn. I’m still completly beginner.

Looks like it resists very well! Nice touch with the LCD loading graphic, too. We’re glad you continue to post updates!

This is amazing!! Will you be posting your code for your projects? I’d like to try and adopt them for use with the stock Zumo.

Thank you!

Here is the link the link for the Arduino!

Hope it will helps you, looking forward for your stock Zumo!
