I have made my first robot with my dad not long ago. My dad wrote the program as I'm not EXACTLY sure how to use the ADC, which I need to interpret the analog … Read more

Need consistent 90 degree turns. HMC5883L and Arduino Mega

I am currently working on a project for school. The idea was to create a robot that could perform pathfinding functions using A*. The path is found using a virtual grid of nodes programmed into the Arduino where "X"s are non-passable objects, "0" as the start, and "1" as the destination.

Not sure how to insert code on this forum. Someone could help me out with that as well...)

Example: 

A pummer is a solar powered self activating LED flasher. Pummers are nocturnal critters that soak up sunlight during the daytime, then get active at night. … Read more
Bumble around with an ESP8266 only driven bot
Well I had a chassis for it, and wanted to make my little ESP8266/NodMCU only bot real, so I am mounting it on a Actobotics Runt Rover Peewee chassis. Read more

Free Range Robots (and hallways)

Uff-da... So I have pulled the training wheels off of Walter and am letting him rove around sans fences. I have actually had great luck with pre-solving a lot of problems (table legs and driving under things) but still I am running into a few problems.

I ask this as an open question.

As I wait for parts for Walter, I decided to get back to my "Start Here" bot. I had an old Playmobile tank which had some pretty fantastic treads on it. … Read more

This 143:1 gear motor is much like the GM3 gear motor but runs at nearly twice the speed. Great for robots needing speed over torque! Read more

Tips for having custom parts waterjet cut ⚙

If you have a sophisticated mechanical design for your robot, you may have considered having the parts made by CNC waterjet. But, as with any tool, there are some limitations to this approach. I created thse articles to explain the limitations of this technology and hopefully make it easier to get the custom parts you need from waterjet cutting
