The new means of mobility for Isaac, 10, who has spinal muscular atrophy and is limited to the use of just a few fingers, means he can more easily travel the halls of Byron Christian School where he is in fourth grade, join peers on the playground and roll around on the trails outside his grandparents’ cottage.
“Up north,” Isaac said when asked where he most looks forward to using the stroller designed by four Calvin College students. Electrical engineering students Matt Rozema and Rob VanderVennen and mechanical engineering students Matt Last and Dan Evans designed the cart from scratch. They spent more than 1,800 hours of their senior year building it before their graduation in May.
