RobotC v4.54 – The LEGO Mindstorms EV3 ‘C’ Programming Language

The ROBOTC Development Team is very excited to announce their latest update, ROBOTC for MINDSTORMS 4.54, which includes new features, functionality, and bug fixes. 

LEGO Mindstorms NXT Coloured Ball Sorting Crane

LegoMindstormsNXTColouredBallSortingCrane

Good things do sometimes come from disasters. A couple of days ago I was attempting to lift down approximately 5Kg of assorted LEGO parts when the container took advantage of gravity, and headed straight to the floor. This ended in a completely empty storage container, and LEGO dispersed for metres about. Towards the end of the cleanup, I came across a pair of Green Mudgaurds from a LEGO Technics 8291 Green Dirt Bike.

Just Monkeying Around

Monkeying Around

This is my latest Mindstorms Project, a LEGO Mindstorms EV3 Robotic Monkey that Climbs his way along a bar made from 25mm PVC Plumbing Pipe.

The Robot uses an EV3 Programmable Brick to control 3x Large NXT Servo Motors and a Medium EV3 Servo Motor. The Medium Servo Motor Rotates the Monkey’s Arms. Each of the Monkey’s Hands is opened and close with a Large Servo Motor. The third Large Servo Motor animates the Monkey’s Tail.This is my latest Mindstorms Project, a LEGO Mindstorms EV3 Robotic Monkey that Climbs his way along a bar made from 25mm PVC Plumbing Pipe.

Computerised Vertical-Lifting-Span Railway Bridge

Vertical-Lift-Span Railway Bridge
Movable Vertical-Lift-Span Bridges have a movable portion deck which remains horizontal as it is lifted vertically. The amount of headroom available is determined by the variations between water levels and the heights of the lift towers. Water traffic beneath these bridges are usually restricted to low-masted craft, barges and tugs.

LEGO Minstorms EV3 Segway Uses Microinfinity Cruizcore IMU

EV3 Segway
I have been working on creating a LEGO Minstorms EV3 Segway which uses Microinfinity Cruizcore IMU (Inertia Measurement Unit). The Robot is programmed using RobotC v4.xx for LEGO Minstorms, and uses the ROBOTC 4.x Driver Suite for NXT and EV3 written by Xander Soldaat. I originally need an extra Segway to exhibit at Brixhibition Launceston 2015, and as all my NXT Bricks were in use I decided to put together an EV3 based version.

Virtual Robotics Toolkit for LEGO Mindstorms EV3

Virtual Robotics Toolkit Sumo
For people thinking of purchasing a LEGO Mindstorms EV3 kit, but are a little worried about the learning curve, then spending $50 on a copy of the “Virtual Robotics Toolkit” before outlaying $500 on the LEGO kit its self.

Mindstorms EV3 Dual-Wheeled Holonomic Platform

Technicolour Holonomic Platform
I have been working on an LEGO Mindstorms EV3 Holonomic Platform, with Dual-Wheels on each of its three sides. It is controlled via a Sony PlayStation Wireless Remote Control. The PS2 Remote interfaces to the LEGO Mindstorms EV3 Brick via Mindsensors PSP-Nx-v4 Adapter.

ROBOTC is the premiere robotics programming language for educational robotics and competitions. ROBOTC is a C-Based Programming Language with an Easy-to-Use Development Environment.

Holonomic Platform for 125mm Rotacaster Omniwheels

I’ve been working on a very solid, Holonomic Platform to be used with the large 125mm Rotacaster Omniwheels as part of my display for the TAZ-Brick Collector Club’s Brixhibition to be held on the weekend of 20-21 April 2013.

Wii-NunChuck Controlled Mindstorms NXT Soccer Robot

Wii Soccer Bot
For the forth coming [brixhibition] Exhibition at the end of April, I have been asked to set-up and run a couple of interactive Robot Soccer fields.The Robots needed to be robust and reliable as members of the public will be interacting with them. Also they need to have a a simple, intuitive, and easy to use hand held controller. I have used Sony Playstation PS-2 Controllers, but they have far too many controls that would be unused and confusing to the first time operator. I chose to use a Nintendo Wii® Nun-Chuck Controller for the job.

Rotacasters: Big, Bigger, Biggest!

Yes it ‘s another Holonomic Platform Robot, but this ones special. I built this Mindstorms Robot to celebrate a package that arrived in the post today from Rotacaster Australia. Yes, more omni-wheels to’ Beta Test’. But these are monsters compared to the original 48mm (2″) Rotacaters.

LEGO Mindstorms NXT Stair Climbing Robot

After seeing this LEGO Mindstorms EV3, Stair Climbing Robot on ‘The NEXT Step Blog‘, I decided to build my own NXT Version. I had attempted a couple before several years ago, but they weren’t overly successful. Now with lots of IMU Sensor add-ons for the Mindstorms NXT, it makes the task a lot easier.

LEGO Mindstorms NXT Rotacaster 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 replaced the 2x RCX type Touch Sensors with 2x NXT type Touch Sensors. The front bumpers had to remodelled to take the NXT Touch Sensors.

LEGO Mindstorms NXT Bin Emptying Robot – Mark III

This is a LEGO Mindstorms NXT “Bin Emptying Robot Mark III”. 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 II version worked well, but was a little unreliable, unlike this version. Like the previous version, it uses a “Ball Repository” to store, mix and reload the Production Line with Balls when the “Ball Sorting Factory” needs them.

LEGO Mindstorms NXT Bin Emptying Robot – Mark II

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 worked well, but it was slow and very noisy, unlike this version. Also this version uses a “Ball Repository” to store, mix and reload the Production Line with Balls when the “Ball Sorting Factory” needs them.
