Play and Mobility Device

Fabrication

A Jazzy Elite ES Chassis was deconstructed for its valuable parts, like the battery holders and motor mount. The round steel tubes were

replaced with square steel tubes and the battery holder was repurposed for a horizontal

orientation.

The car seat mount and bumper connections were welded.

The rolled steel bumper was bolted to the frame and painted.

Background

Children with impaired mobility may have trouble moving around normal spaces. This device is being designed to best fit Lucas, a 3 year old boy with cerebral palsy. This condition makes it difficult for him to control his gross motor skills. Our device will give him the opportunity to be in control of his movement.

Requirements and Specifications

Design

A mid-wheel drive device was designed as a modification of a Jazzy Elite ES power wheel chair base. The round tubes were replaced with square tubes for better weldments. The battery holders were changed from vertical battery placement to horizontal to save space. Extra supports were added to the frame to securely mount the child seat. Casters and a suspension system were designed for better maneuverability. A bumper guard was designed for slight impact absorption and slipping against walls.
