3D Graphics 
Robot Laser Cutter simulates the operation of a robotic arm with all the operating functions of a real robot. 
Robot Laser Cutter brings to the classroom an easy to use interface with a realistic 3D graphical robotic arm at an affordable price. This program is useful to demonstrate the principles behind a robotic moving arm and enable students to write control programs that use a laser beam to cut through strips of plastic on a table. This simulates a typical robotic arm scenario found in industry. The student Controls the robot by clicking on icons that control each of the robots stepper motors. The parts of the robot are colour coded for easy identification. 
Program robot arm with powerful control language 
This program is useful for schools coding software requirements. A powerful programming language is included that allows a script of commands to control and move each element of the robotic arm. The language uses simple commands that students can get to grips with quickly. Robot Laser Cutter is specially designed for use in the classroom, this is reflected in the easy to use programming language, Programs contain primitive commands such as: – 
All commands can be placed in procedures. The robotic arm incorporates sensors enabling feedback to be used in programs. Decision-making IF statements and loops with the REPEAT and WHILE commands can be used in programs. The MOVE command allows easy movement to a specific Cartesian co-ordinate. Programs can be saved for future use. 
Laser cuts through objects. 
The laser cuts through plastic sheets that are placed on a table. The robot can use X,Y,Z Cartesian co-ordinates to move to a specific point. Robot Laser Cutter features a 3 dimensional version of a robotic arm at a price much lower than a comparable real arm.



Teach how a hard disk drive works

Visual Hard Drive simulates the operation of a computer’s hard disk drive and shows how a hard drive works. The virtual drive has a controller board, four magnetic platters and eight read/write heads. Up to 32 bits of data can be written and read from the hard disk drive. The drive simulates data being written and read from the top platter and shows how a hard drive works.vishd5
Virtual data can be written in a safe environment. Data can be read from the virtual disk and be displayed as binary, bytes and ASCII.

Visual Hard Drive has four magnetic platters and eight read/write heads.

Data limits
Our hard drive is fixed to write at sector 1 from here we can write 32 bits of data. In total 32 bits of data can be written to the disk.
The program simulates data being written to sector 1. The start address is 0000000200 Addresses are offset from this start address.
Write to disk

Every part of the platter has its own unique capability to store a binary 0 or binary 1 when writing to the platter the magnetic surface will contain either 0 or 1. In our simulation a red dot signifies a 0 a gap signifies a binary 1. As the disk is spinning all the time a circular data trail is left.
Visual Hard Drive shows how a hard drive works.

Robotics in the Classroom

Teaching robotics in the classroom can be a time consuming business for the teacher. Setting up a classroom full of robotic arms connected to computers is fraught with problems. Quite often going through a lesson with robots breaking down the whole process can be a chore.


We have introduced Interactive Robot this provides a 3D robotic arm on screen that picks up and moves items. The coding language features simple commands as well as X,Y,Z move command.

With the robot on screen this takes out one factor of the reliability issue.
