Current science and technology are developing by leaps and bounds thus providinggreat benefits in all aspects of human life including the robot-a robot designed toassist human tasks through supervision and human control, or use the program. The development of grass that propagate ground quickly often make nursing groundshave to mow the lawn with regular intensive. Related to this, then the tool in the form of a single intelligent robot cutting grass-based Pi B+ raspberry is the application ofrobotic systems that aim to control 2 motor Driver l298n useful for running gear boxwheel robots and grass cutters on Dynamo cutting tools lawns without a crew. The programming language used is the language which has been running pyton Apache Web Server. So by designing Intelligent robot prototype lawnmowing rasbery Pibased B+ using a web browser at the time grass has begun to grow tall, grass-cuttingIntelligent robot can directly perform cutting grass with a controlled web browser.

Running text or commonly known as text running a medium to deliver information that is most often encountered as a means of advertising that are informative. Running text display is generally in the form of LED-LED are connected and assembled into a row of LED or may be a dot matrix. Submission of information by displaying the running text has not been effective and efficient in terms of use. There are still shortcomings that enable people to experience vision errors and too long waiting for the text to be displayed. Thus the necessary tools to deliver information that can work optimally to minimize shortages by designing a control tool running text using voice (voice) and arduino uno. This tool uses a series of android smartphones facilities to provide input sound is converted into a data string and compiled in arduino using serial communications, and will be displayed on the LED Dotmatrix as output. Submission of information by using running text that comes with using sound can improve efficiency and effectiveness in the use and also the time required so that it can reduce the level of difficulty of the user in receiving the information
