Large Scale Specialized Robots

Omnidirectional Travel, and Fully Equalized Loading Suspension for Large Robot Applications.

Ultra-large robots can now have full precision mobility on even badly deteriorated existing plant floors. Uneven surfaces and relatively thin floor slabs are not a problem for the equalizing suspension, all-directional steer technologies. The inherent raise/lower capability of Uniload's suspension allow robots to move to work stations and lower onto precision location reference points or alignment cones. The SynchroSteer computerized steering will work under the control of any automatic guided vehicle navigation system. Other than the inherent omnidirectional capability of air bearings, the only other claim to omnidirectional mobility with wheeled systems, is in the US Navy's interest in shipboard weapons loading systems. For the last twenty years the Navy's interest has been based on and original Swedish patent for and omnidirectional vehicle (ODV) where a vehicle's four-wheel arrangement consists of six powered helical rollers, radially spaced around the periphery of each wheel.  By controlling the rotational speed and reversible rotation of opposing wheels, the vehicle has the capability of achieving a fully omnidirectional travel capability, within limits.  The technology is currently promoted by AIRTRAX, INC. of Hammonton, NJ. It is reported that they are contributing support to the Armament and Technical Products arm of General Dynamics is in a joint development program with the NAVSEA Philadelphia Code 977 command the Lockheed Martin company.  Airtrax currently markets a line of forklifts and scissors lifts under their Sidewinder brand name.

Wheelift's omnidirectional design has taken a much more practical approach by borrowing from the highly efficient and worldwide-proven European self-propelled modular transporter (SPMT) technology, where loads weighing literally hundreds of tons have the inherent capability for all-directional movement in over-the-road and outdoor assembly applications, Wheelift has developed an open-center axle , pivotal center column design to closely parallel the European technology, The resulting wheel modules are inherently much smaller, while still allowing very heavy carrying capacities. The much smaller wheel diameters can accommodate very low platform heights.  For indoor applications, the Wheelift technology, does in-fact efficiently and effectively move incredibly large loads in highly confined spaces and over virtually any type of floors, while being perfectly capable of dealing with severe floor unevenness and manufacturing debris.  Wheelift handles the loads that are beyond the capacity of forklifts, and/or where increased maneuverability is paramount. That capability is a must if robot manufacturers want to build larger units to increase their markets and respond to industries needs in much heavier applications.
