The is a multiplexer to connect 4x NXT sensors to single NXT port. The multiplexer can connect any sensor designed for Mindstorms NXT, both LEGO and/or third party sensors. The is requires an external battery source supplying a voltage range between 6 and 8.4 volts to operate. Mindsensors recommend using LiPO battery or 6-AA battery pack. [...]
My decided to die on me at a most in convenient time whilst building the Mark II version of my 'Bin Emptying Robot'. I was forced to use limit switches instead. After talking to Deepak Patil from , he suggested I take a knife in hand and disassemble it. The process was straight forwad enough, [...]
This is a LEGO Mindstorms NXT "Bin Emptying Robot Mark II". It is part of a larger project I have been working on, my "Ball Sorting Factory". A forklift delivers full Bins of balls to be emptied. The Emptied bins are then taken away to the processing facility to be refilled. The Mark I version [...]
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 [...]
The Mindsensors GlideWheel-M, Power Functios (PF) Motor controller for the NXT is designed to control PF motors from NXT. Providing high precision speed and rotation control, in an easy to use design. The GlideWheel-M PF Motor controller allows direct connection of PF Motors to your NXT. No extra power needed as Power for the motors is [...]
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 [...]
I have received a pair of Mindsensors' GlideWheel-Ms, Motor Controllers to Beta-Test. The GlideWheel-M is a motor controller for (PF) Motors that allows you to connect Motors to NXT Motor Ports. Using the built in encoder, the GlideWheel-M, allows rotational control of Motors. The GlideWheel-M is connected to the NXT Motor Port via NXT a [...]
This is Part 3 of my Melon Factor Project, which is part of my NXTLog Food Factor Competition Entry for May 2012. In Part 1 of my project, involved transportation of the Melons using a Forklift Truck to transport the boxes of melons from the delivery depot to the processing plant. Part 2 of my [...]
This is Part 2 of my Melon Factor Project, which is part of my NXTLog FoodFactor Competition Entry for May 2012. In Part 1 of my project, for the transportation of the Melons I had them in 'Bottom Drop' Boxes. I used a Forklift Truck to transport the boxes of melons from the delivery [...]
This is my LEGO Mindstorms NXT Quad Caterpillar Track Crane, which uses my 'Ultimate Grab' to pick-up and retrieve a Hitechnic Infra-Red Electronic Ball. The Chassis houses 2x NXT Motors to drive the Left and Right pairs of Tracks. A third NXT Motor is used to raise and lower the crane arm. A Small PowerFunctions [...]
Both the LEGO 7.4 Volt Rechargeable Batteries for Mindstorms NXT, are of Lithium-ion Polymer construction. Lithium-ion polymer batteries are light weight rechargeable batteries.
After the proof of concept with Mark I, I have totally rebuilt the chassis using 12x Rotacasters in pairs.
This is my ExoForce Rover Wheeled Prototype Chassis. Using the 'Exoforce Wheel Mounts' discussed in my previous post, I now have the basic chassis set-up. The Chassis allows both the front and rear wheels to be driven. Also both front and rear axles steer in order to help to decrease the robots turning circle. CAD [...]
Lookout NASA, you have Rover competition. And it uses the amazing Rotacaster Omni-wheels for unsurpassed manoeuvrability in confined spaces. The Mars Rotacaster Rover is based on the current NASA Mars Rovers with their unique suspension set-up. Link to this post!
Part I Lookout NASA, you have Rover competition. And it uses the amazing Rotacaster Omni-wheels for unsurpassed manoeuvrability in confined spaces. There is no need of a steering mechanism to turn the Rotacaster Rover thanks to the unique wheel design. NASA Mars Spirit Rover I've had a few attempts, going back to the days of [...]
Still got that container on the bench with a pile of unsorted resistors left over from projects, or perhaps have purchased a mixed-lot of assorted resistors to begin with. Resistors have colour bands printed on them, rather than numeric values, which makes them more difficult to sort in you don't know the resistor colour-code of [...]
I needed a LEGO Mindstorms NXT Cable Checker to allow me to Verify my NXT Connector Cables for connectivity or faults. A tester is particularly useful for when you are crimping your own cables. I picked up a cheap Network Cable checker of eBay for $2.50, and hacked it to suite NXT Cables. Unfortunately it [...]
Love Linux, have a Mindstorms NXT Kit, and your wishing for a Mindsensors NXTCam-v3, that works in Linux! If you are a Linux user and own a Mindsensor NXTCam, you life has just become a lot easier with aNXTCam. aNXTCam is a native Linux software suite written by Janosch Gräf for the Vision Subsystem v3 [...]
This is a LEGO Mindstorms NXT Crane which delivers balls to a Coloured Ball Sorting Conveyor System. The Ball Sorting Conveyor System uses RC Servo Motors to control the Conveyor and Sorting Mechanism. A single NXT Brick Controls 4 standard 180° RC Servos in the Sorting mechanism and another is used for the Crane's Grab. [...]
