CAD Data of the Electric Wheelchair Model

March, 2001 by Koichi Hirata and Hiroaki Sakakibara



The electric wheelchair, which is shown here, has not match the weight and the center of gravity to a real wheelchair yet. Also, torque and speed of a pulse motor are not enough performance for experiments. We hope that you will build an original one with reference of the CAD data of our model.

The CAD data is made with AutoCAD LT 2000 of Autodesk Inc. WHIP! allows you to distribute CAD (DWF format) files over a network without AutoCAD software. It is available for download free of charge at the web site of Autodesk, Inc.

Also please note that the CAD data includes Japanese fonts and characters, they may not show correctly on your PC.
