GeckoSystems' Mobile Robots Employ Low Cost Locomotion System Components
CONYERS, GA, Jul 21, 2009 (MARKETWIRE via COMTEX) -- GeckoSystems Intl. Corp. (PINKSHEETS: GCKO) described today the electro-mechanical architecture of their low cost locomotion system in Part 2 of a four part discussion on "basebot technologies." GeckoSystems is a dynamic leader in the emerging Mobile Service Robot (MSR) industry revolutionizing their development and usage with their "Mobile Robot Solutions for Safety, Security and Service."
Basebot technologies are the power, locomotion, sensor and software requirements of utilitarian mobile service robots (MSR's).
"Once we determined the size and capacity of the battery compartment and its weight, we calculated the power needed from a 12VDC permanent magnet gear motor to lift the robot (the CareBot weighs, with battery, approximately 90-100 lbs, total) readily over vertical transitions up to 1.5" as are commonly found in many homes. We determined that not only was the quality of automotive accessory gear motors excellent with a low cost, but also very durable and powerful," observed Martin Spencer, President/CEO, GeckoSystems.
GeckoSystems invented a low cost means of adding an optical encoder such that they can use a closed loop system to manage the individual motor speeds with GeckoMotorController software.
"In our years of testing these modified, but commodity motors, even after many hours of continuous use, they seldom get warmer than room temperature. Our proprietary energy conservation paradigm further improves the efficiency of out low cost locomotion system for a greater value to out end users and increased ROI for our stockholders," concluded Spencer.
The GeckoMotorController software runs on a 20Mhz CPU utilizing PWM to control two 50A H-bridges to precisely set and maintain speeds on the differential drive motors for "straight line performance" and "bicycle smooth avoids."
