Interactive Primary Newsletter 26 "Don't talk to me about life" or all about a Robot Arm

ICT    Is it worth it?       Prices To use the robot arm with a computer an interface board is needed and one is supplied with the MOVIT LAB software. The interface uses the same socket as the keyboard on the base of the robot. There are also 2 light sensors attached to the board, The figure to the right (click for larger image) shows the interface board and a sensor. The sensors act as switches and a sample program using sensors is given in the demo mode. The software to program the arm uses a high-level computer language, which is easy to understand and use. Those familiar with Basic or LOGO should have no difficulty in writing programs. When the software is loaded a screen prompts the user to choose a mode of operation ( click for larger image). Keyboard direct mode enables the various parts of the arm to be activated in a similar way to the keyboard. A demonstration program in the software gives an idea of the simple commands needed to grab and lift an object. For those who like to use flowcharts there is also an example of a flowchart for this demo program. An added attraction is a thumbnail video clip showing the arm in operation. Figure 8 shows a demo program mode with video screen. Warning software is only available for Windows 95 and 98

Is it worth it? The robot kit, leaving aside time for assembly, appears to be a good buy. Our only reservation, is it robust enough to stand up to work with pupils and why no Mac software? With those reservations in mind we believe the arm if bought on it's own or with the software is a good buy for 5 -14 work in science, technology and ICT. The software may seem expensive but with both arm and software all of the control outcomes shown in the guidelines can be overcome. If the pupils are considered to be responsible enough to carry out the building of the robot this will certainly contribute to a few more ticked boxes. As a bonus for those working with Basic Stamp, PICAXE or PIC Logicator this is a marvellous opportunity to add another working model for work in S1/S2 or Standard Grade.
