Step : 4

Now bend a flexible strip from hole no. 5 and 9. Break it from hole no. 14. Fix 2 three hole connector in the center of the folded flexible strip as shown in Fix this structure to the shaft of the motor by adding fillers and lock it with the axle lock. Fix a wheel between the bent flexible strip with help of a 3 inch axle shaft as shown in the image.
Step : 5

Take a short L & add a motor on the first center hole and add a big round gear to the shaft of motor. Fix this short L to the short rectangular plate on the center hole of row 4 & 5.
