Frog
Enabling Mobility
The Frog walker enables children and young adults with moderate to severe mobility impairments. The weight compensation seat assists users in standing and sitting independently without extra assistance. A multi-stage adjustable seat lift system allows caregivers to control the assistive force during the course of physiotherapy sessions. It caters to patients with a wide range of sizes, stability and control.
Myself and the team at Xentiq partners approached this problem from the bottom up. We worked in close collaboration with the physicians and children from the Cerebral palsy Alliance of Singapore, listening, developing and testing our prototypes with their close guidance each step of the way.
By creating an adjustable frame structure we were able to progressively improve the walker one subsystem at a time while accommodating children of different heights.
We used our in house CNC machine to fabricate components from ABS, Aluminium & Delrin. Once the plastic parts were up to spec we sent them out for low volume vacuum casting.
The spring assist mechanism of the seat was fully designed, prototyped, developed and fabricated in house using a combination of machining and 3D printing. This allowed us to continually improve the efficacy of the solution without high up front costs.
The elastomeric handles were fabricated in house by using room temperature two part polyurethane casting rubbers molded over an aluminium tube inside an acrylic mold. By creating these in-house we were able to experiment with laser etched textures, shore hardnesses and tints.
