Another blog - you kidding me ?
Ohhhh so lucky readers - here is a video showing the Pool Butler's TE connectors and where thewires/signals go to and from.
Its only 4 minutes long, so save your trip to the bathroom until its done.&n...
In this blog, I will cover some details about mounting the robot's structure. The central system was made with PLA, some bearings, and a bunch of bolts. As I said before the main idea is based on an open-source robot, I took the main ideas and mo...
In this blog entry, The Robocat will get its chassis, motors, wheels, and main system controller. This robot will have two drive wheels plus a caster ball for stability. The chassis I chose is the
Octagon Chassis Frame from Adafruit...
Unlimited CNC Robot Blog #4
In this update I will show where I am at with my project and setting up the laser. I will also show what I have added to my project. As a note, I don't do many videos so this won't be perfect.
Please watch the vi...
Intro
This blog introduces Sammy Semaphore actually using semaphore signals to send a message. I have to apologize for skimping on showing more build steps. I am really under the weather - high fever, I can hardly think, productivity is down around 5...
The Arduino Uno R3, DFRobot DRI0017, and DFRobot DFR0502 all use .1” female sockets for IO connections.
Prototype projects usually use stripped 24/26 AWG wires or pre made jumpers like these https://www.newark.com/adafruit/759/wire-ga...
In this blog, I'm writing about the software that controls Rullit
1. Introduction
Rullit will follow a simple path, shown in picture
The goals of the control software is to
constantly monitor the limit switches, to prevent the robot from falling f...
Connecting the engines
The following photo shows the connections to the truck engines. The engines are connected to the motor driver shield using the metallic connector provided in the kit.
Connecting the sensors
The next photos show the...
There's been a long time since my very first post, it has been a difficult challenge in terms of getting materials and most important my kit, due to my country restrictions, but let's talk about business.
In my first blog I said some things a...
Intro
While waiting for components I've been busy designing some 3D printed parts and wiring up some of the connectors that I do have. The first section of this blog shows one of my favorite types of connector from TE Connectivity, actually the ...

Assembling the robot platform
Today's update is creating and assembling the final robot platform.
The previous one was for testing and making sure everything works. I received the material that is required for comp...

In this post, I am showing some picture I took during the build of the robot
1. The chassis
The robot chassis is made of 10 mm plywood. I cut out all the slots and holes to mount the robot components. To limit the total height, I also created a slot...
This is blog #8 - Everything you did and didnt want to know about the mystical and magical Pool Butler Steering system
1. The video of the steering operation in drydock. https://youtu.be/54yKQ6vUuSc

This is my second blog post and since my last one, my dad and I bought a robot kit. Like I said in my post, there is a small board which the motors sit on. We are designing a rear wheel holder, which we will 3D print. We are planning on using a ping ...
Obstacle detection
For obstacle detection my mobile robot will use two HC-SR04 ultrasonic sensors. One sensor will be mounted at the front of the truck and the other at the back of the truck so that obstacle detection will be possible in both forward...
Just like at work, as a proposal develops into the prototype, the spec changes on the lessons learned during the build.
My best wish would to have several of these SMD relays in the final design. For expediency, I'm using just the one provided in the...
In this post, I will write about how I use the Arduino board, the DFRobotic shield and the TE connectors
1. Connections overview
Picture below shows the components and the wiring
Main components are

The Pool Butler (airboat) has 2 plastic covered sandwich enclosures to protect the electronics from water.
Some of the interconnections are in between the boxes, and some wires are to devices outside the boxes.
A wire schedule is used in ...
The Twist, Turn, and Move Robotics Design Challenge with TE Connectivity
IntroThis project has a lot of moving parts (literally) and not all parts are here to be worked on so I will have to work on bits that I can while waiting for deliveries. This b...
Mechanical design
In this blog, I will try to explain the considerations I made to come up with the final mechanical design. The criteria the design must met are
The cables must be winded inside the robot. It’s not desirable to have cables han...
Introducing The Robo Cat
My daughter and I have lots of fun designing and building robots together, so naturally, we jumped at the chance to participate in the Element14 Twist and Turn and Move Robotics Design Challenge. Our goal with this pro...
In Pool Butler Blog#4 , a statement was made that limit switches or a home switch would be needed to locate the Pool Butler's (airboat) rudder's position after power up.
The control is envisioned to use CW and CCW touch switches to move the rudder to...
Preliminary work
I removed the cabin of the truck and took out the windshield so I have more room for mounting the control hardware and power supplies on the truck.
I then tested the remote controlled car. It is in working condition. Car is powered ...
