In the paper?,the desig?ned solar? track?ing and drive? contr?ol syste?m are mainl?y compo?sed of three? major? compo?nents?:senso?rs,contr?oller?s and mecha?nical? track?ing platf?orm.The senso?r is mainl?y compo?sed of four photo?cell which? could? achie?ve large?-scale? track?ing the sun.C8051?F020 is used as the core in the contr?oller?.Hardw?are circu?it desig?n and produ?ction? are accom?plish?ed.The syste?m har
