LEGO Mindstorms NXT Bug Bot

I originally built this LEGO Mindstorms NXT Bug Bot Robot as part of a display at the TAZ-Brick (www.tazbrick.com) Collector Clubs Brixhibition North. The robot proved a hit with the under 10, LEGO Fanatics. Since then I’ve been playing around with the design of my Mindstorms NXT Bug Bot. In this new version I have [...]

LEGO Mindstorms NXT Bin Emptying Robot – Mark I

This is Mark I of my LEGO Mindstorms NXT Ball Sorting Factory, which I have been working for a number of weeks. The whole project consists of three main parts. Firstly there is the 'Ball Sorting Factory', made up of Gantry System with 3-Axis: Front-Back, Left-Right, and Up-Down for the Ball Gripping Claw. The Second [...]

I'm currently working on a Sorting Factory, complete with LEGO Mindstorms NXT Forklift Truck and Bin Emptying Robot. Part of a larger project I'm currently working on (partly visible in the upper-left corner of photographs). The Forklift is used to deliver full Bins of balls to be emptied by the Bin Emptying Machine, and then [...]

Tweeting Data with NXT2WiFi Webserver Module

In this Tutorial we will go through the steps required to have your LEGO Mindstorms NXT Data sent to Twitter using the NXT2WiFi Miniature Web Server Module. In this Tutorial, the code used to program the LEGO Mindstorms NXT is . You will also need a Twitter Account, if you don't already have one. To [...]

Connecting the NXT2WiFi Webserver to a WLAN

The simplest way to connect to the NXT2WiFi Mini-Webserver Module is via an Ad-hoc Network, also called WiFi Direct network where devices communicate only peer to peer (P2P). There is no base and no one gives permission to talk. But this method is limited to the fact you can only have access through a single [...]

NXT2WiFi: Using Webpage Sliders to Control Motors

This tutorial follows on from my previous NXT2WiFi Articles. In this example is used to program the NXT. Using Webpage Sliders to Control LEGO Mindstorms NXT Motors with your is relatively easy. You will need to have the latest  Custom Webserver Source Code in order to use Slide Controls. Whenever the user interacts with the webpage, the NXT2WIFI [...]

RobotC: NXT Beach Buggy Controlled via NXT2WiFi

This LEGO Mindstorms NXT Beach Buggy is controlled via an Internet Browser Interface using a LEGO Mindstorms NXT . This is my first project using one of Daniele Benedettelli's . Any Internet Browser capable device can control it. The NXT2WIFI is a miniature Webserver Module featuring a fully integrated 802.11 b/g/n Wi-Fi interface, giving your LEGO® MINDSTORMS® [...]

LEGO NXT Thermometer using CatCan SmartSensor Lite

I decided to put my CatCan SmartSensor Lite's Temperature measuring capabilities to use by constructing a simple LEGO Mindstorms NXT Mechanical Linear Display Thermometer. The Thermometer is graduated in 1 Degree Celsius increments. The Display pointer is driven via a NXT Motor connected to a conveyor belt built from old style Technic Track Elements. As [...]

LEGO Mindstorms NXT Forklift – Mark II (Follows Line)

My Original Forklift was part of my NXTLog FoodFactor Competition Entry, which needed a method to transport models of the large open top pallet type bins used to transport vegetables, such as potatoes, cabbages and pumpkins. I decided on a Forklift Truck to do the job. I felt that the original Forklift's Mast Lifting and [...]

NXT2WiFi, Webserver Sensor – Getting Started Guide

My NXT2WiFi, Webserver module for LEGO® MINDSTORMS® NXT robots arrived a couple of weeks ago from Daniele Benedettelli. I finally got around to unpacking this new sensor today. In fact the weather here today made the decision very easy. You can use the NXT2WIFI adapter to control everything on your robot from your Laptop, iOS [...]

Using LEGO Mindstorms RIS (RCX) KIT with Windows7

Installing LEGO Mindstorms Robotics Invention System (RIS) on to a Windows7 PC is frustrating to say the least, as I've just discovered this while setting up my son's computer to allow him to program my old RCX's. After dusting off the RIS 2.0 Disc, everything installed properly, but when I ran the program, the computer [...]

LEGO Mindstorms NXT X-Y Plotter

  I’ve have built my first LEGO Mindstorms NXT Plotter (printer) which is programmed with RobotC. The plotter draws pictures by drawing whole lines, known as vectors. An X–Y plotter is a plotter that operates in two axes of motion ("X" and "Y") in order to draw continuous vector graphics. The term was used to [...]

Rotacasters: Big, Bigger, Biggest!

Yes it 's another Holonomic Platform Robot, but this ones special. I built this Robot to celebrate a package that arrived in the post today from Australia. Yes, more omni-wheels to' Beta Test'. But these are monsters compared to the original 48mm (2") Rotacaters. These new [rotacater] measure 125mm (5") in diameter, and weigh in [...]

RobotC: Autonomous Holonomic Platform using 4x Sonars

This Autonomous Tri-Drive Holonomic Platform is fitted with and uses 4x Ultrasonic Sensors for navigation. The RobotC Code is based on my previous post on using multiple Sonar Sensors in RobotC. The main challenge is to use all 4 Ultrasonic Sensors without them interfering with each other, resulting in non-valid measurement readings for distance values [...]

RobotC: Using Multiple Ultrasonic (Sonar) Sensors

When using Multiple Ultrasonic (Sonar) Sensors together, you need to configure the Sensors to use ‘Single Shot Mode’, so only ONE Sensor is taking a measurement at any time. If you have all the Ultrasonic Sensors on at once they interfere with each other and give incorrect readings. To get around these issues, you need [...]

PS2 Controlled Holonomic Platform Using RobotC

Yes, another Holonomic Platform. My son, Anthony requested a Holonomic robot to take to school for show-and-tell. So here it is with a few scholarly extras, including the code. A Holonomic platform is one of the many types of Holonomic drive trains — it can move forward and backward as well as left or right [...]
