Project Robotics - March 2009 - (Page 22) figure 8 hot-V platform components. The hoT-v plaTform, in addiTion To being much larger Than The loT-v, is also much more powerful loT-V, is also much more powerful (see figure 8). it has a power support system capable of delivering several hundred amperes of current allowing the motors to run at over 3 horsepower. Compactrio was chosen for its shielding and isolation properties, in addition to its small, rugged form. While the hoT-V platform was totally self contained, it was important for us to be able to monitor and interact with the system during operation. The VoluMe 1 22 || nuMBer 1 internet-ready lan adapter on the Compactrio allowed us to install an 802.11 wireless router inside the system. This decision increased the functionality of the system by an order of magnitude by creating a wireless communication connection with the system; the team was able to control the hoT-V from multiple platforms. The team then decided to integrate an hp ipaQ pocket pC into the operation of the hoT-V, using the labVieW pda Module to stay on the labVieW platform. The pocket pC runs a labVieW program that allows two operating modes: heads-up display: While the user is riding the hoT-V, the ipaQ displays information about the state of the platform, such as how much battery life is left and how much power it is currently consuming. (The ipaQ can be clipped on to the hoT-V’s handlebars.) remote Control: When the user is not riding the hoT-V, the user can remotely control the platform from the ipaQ. The user has the option to control various parts of the system and control movement. adding the palm-sized user interface turned the hoT-V into much more versatile experimental platform. While the team was able to conquer many significant design and implementation challenges, perhaps the most significant was the short time frame in which it was undertaken and completed. The entire design from conception, through modeling and analysis, experimental validation, and control design, to construction and implementation was completed in a four-month period. The team attributes this success to the single development platform and tight integration of the ni hardware and ni labVieW software that allowed for a streamlined progression from modeling and analysis, to prototyping and deployment. |pM rensselaer polytechnic institute www.rpi.edu.
