Using three IR sensors, SensingBot can sense the front obstacles so it can avoid them.

2. Put the motor frame fixed with the DC motor on the main frame and tighten it only using bolts.

3. Tighten supports on the main frame using bolts. (supports that is located on C4 and G4 are supposed to be fixed on the bolts that are tightened to the motor frame.)

4. Insert the wheel into the DC motor. Insert he bolt into the main frame then fix it using nut and cap nut.
