Until now, the words balance, stairs, and 4-wheel off road were not synonymous with wheel chairs. That was until the inventors of the iBot 4000 introduced their revolutionary wheelchair. This stupendous wheelchair must be seen to be believed.

How does the iBOT® Mobility System work?
The iBOT® Mobility System contains patented iBALANCE® Technology, an integrated combination of sensor and software components and multiple computers that work in conjunction with gyroscopes. Gyroscopes are motion sensors that help maintain balance. When the gyroscopes sense movement, a signal is sent to the computers. The computers process the information and tell the motors how to move the wheels to maintain stability. This electronic balance system is custom-programmed to the user’s center of gravity, to monitor and respond to subtle changes in motion. Reach forward to shake hands, and your iBOT® Mobility System moves with you. Lean back and it moves away as well. The iBOT® Mobility System constantly realigns and adjusts its wheel position and seat orientation to keep the user upright and stable at all times, even when driving up and down curbs or inclines. In addition, the iBOT® includes built-in triple redundant backup systems, as well as auditory and visual signals to provide even more safety and assurance.
