Robots with Wheels

10 Posts authored by: dubbie
Finally, my last post for RoboBoBLet on what I used the prize winnings for. I meant to do this sooner but the summer in the UK was just so nice I have spent most of the time outside landscaping my garden. I decided to use the $100 to buy the Arduino MKR 1010 WiFi Bundle so that I could practice and investigate more of the IoT things with Arduino. I'm hoping to use the MKR 1010 WiFi in a future Project 14.   ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   The journey for RoboBobLet for the Robot with Wheels challenge has come to an end for me as there is no more time left. I added V53L0X laser rangefinder to the 3D printed front piece added to the front of the Pixy camera and connected everything to the Nano. Apart from one head-scratching moment when ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Another step towards the completion of RoboBobLet is to add a camera system. It would be possible to add a simpler digital camera to RoboBobLet and then use the Arduino to do some simple image processing but that would take more time than is available. An alternative is to use the Pixy Camera system ...

Robots with Wheels Enter Your Electronics & Design Project for Your Chance to Win a $100 Shopping Cart! Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   As an alternative to working on RoboBobLet for the Robots on Wheels challenge I decided to make a new mobile robot for a children's club called Messy Church that I am involved with. They wanted a marble tilt maze game but this seemed a bit dull so I decided to make it a mobile robot tilt maze game i ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   I was a bit disappointed to find out that the laser distance sensor I am using doesn't have a narrow 1 cm beam. I am not too surprised as I couldn't understand how they could fit all the optics into the small package of the VL53L0X, I think I assumed it was some sort of electronics magic unknown to m ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   For the first environment sensor for RoboBobLet I thought I would try and use the VL53L0X based PCB from Pololu and associated Arduino library (VL53L0X.h). This is some sort of time-of-flight laser rangefinder connected via the SPI bus to the Nano. I just used the standard connections for the SPI bu ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   To control RoboBoblet a communication link is needed. For this I decided to use a HC06 Bluetooth interface as they are cheap and easy to implement having only four connections (0V, 5V, Tx, Rx). I like my user interfaces to be text based with all the intelligence on the controller and then using a du ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   I thought I would try and measure the speed of the continuous servo motors so see how this varied with the servo setting. I am using the Servo.h library so the servo settings are between 0 and 180. For a continuous servo motor 90 is stationary. Values above 90 are direction and values below 90 are t ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   I decided to use a fairly common chassis from feetechrc (www.feetechrc.com) FT-MC-003 available from several distributors as it provides the four continuous rotation servo motors as well as the wheels and rubber types, plus the chassis which all fit together nicely, albeit a bit fiddly. The photogra ...
