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     Although as a kid, for some reason, I thought R2D2 hovered like a land speeder.  He actually had wheels which can be seen in a lot of shots in the movies - even the prequels and sequels.   For the Project 14 Robot ...

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 ...

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 ...

A pingpong ball was used as a skid and the wheels ...

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 ...
