Create a cart the will wind itself up a ramp with a 45 degree angle with a string while carrying a 5 pound weight.

Many obstacles to find a powerful motor or adequate gearbox that will create enough torque to pull the cart up keeping in mind the battery supply that cannot be plugged in to an outside source such as wall outlet. Began with theoretical values to find motor specifications and gearbox ratio that will accomplish the objective, from that 4 protypes were made where 3 of four failed. Resourcefully the motor and battery from a child's toy car was used.
