Next to obstacle avoiding robots, the most common beginner bot would be a line follower. I myself love line followers, and they are some of my favorite weekend … 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

Lazy Sunday afternoon...

I had ordered a few things from ServoCity and was mucking around with them today and made this:

I new bot chassis to play with. "Clamps"!

I After seeing the new Actobotics runt rovers and getting my hands on one, I find that I like them a lot for a quick inexpensive chassis.  Anyway, I have always loved boxy cars and was a Volvo owner for a long time. I had to have this one (Half Pint) since it's so, you know boxy! :)  Thinking of putting a gripper and a cam on it. Lot of room in the box!

 

There are many ways to build a robot, from scratch a kit, a prebuilt system or combination of any of these methods. The path we will take here will be mostly from a … Read more

ESP8266 running NodeMCU as a controller

The ESP8266 is very powerful little module, but a very picky one as well. In working with original ESP-01 I had very limited success with it and it just acted "flakey". I do understand now what most of the issues were with this module. 

This looks interesting.

A larger broken out 8266 board. Looks like it would be a neat little IoT quick-start board for small applications.
