Programmable robot automates loads of heavyweight material-handling tasks
Model GT3 (General Purpose Tugger) moves loads weighing up to 3,000 lbs. Ideal for automating jobs in warehouses or distribution facilities, such as pulling carts, delivering palletized materials, positioning supplies in tight areas or packaging trash. Vision-guided operation uses stereo cameras to build a 3-D map of environment. Operator teaches robot the route and task by walking through the delivery path alongside the robot and its load. The onboard cameras then record the path just traveled, enabling robot to complete the task without operator intervention for subsequent jobs. Robot stores up to 15 miles of delivery paths and unlimited unique paths, which can be located in different areas of one facility or in separate facilities. Behaviors such as pauses or horn beeps can be programmed into paths. Built-in obstruction sensors, along with tightly controlled speed and steering, reduce potential for collisions. Runs on three 36-volt, 185-amp batteries. Also offers manual mode to serve as a regular piece of power equipment that eases loading and unloading jobs for worker. Options include sound annunciator, safety beacon and spring hitch. Seegrid Corp., Pittsburgh, Pa.
