機(jī)器人是工業(yè)4.0之根本
工業(yè)1.0是蒸汽動(dòng)力出現(xiàn)的生產(chǎn)機(jī)械化；工業(yè)2.0是電力出現(xiàn)推動(dòng)的大規(guī)模生產(chǎn)；工業(yè)3.0是電子信息技術(shù)發(fā)展而產(chǎn)生的自動(dòng)化生產(chǎn)；工業(yè)4.0是基于智能制造的第四次工業(yè)，由德國(guó)率先提出，旨在通過實(shí)體物理（cyber-physicalsystem，cps），即信息通信技術(shù)與自動(dòng)化制造相結(jié)合，將制造業(yè)進(jìn)一步智能化?；谙嗤睦砟?，美國(guó)也提出了工業(yè)互聯(lián)網(wǎng)的概念。
　　
工業(yè)化的進(jìn)化歷程
工業(yè)4.0的實(shí)現(xiàn)分為四個(gè)階段：階段是智能單機(jī)設(shè)備的互聯(lián)；第段是通過傳感和射頻等數(shù)據(jù)記錄和實(shí)現(xiàn)工廠的數(shù)字化；第三階段是材料、和硬件的集成；后就是工業(yè)4.0的實(shí)現(xiàn)，即各個(gè)數(shù)字化工廠之間的互聯(lián)。
　　
現(xiàn)階段歐美基本已經(jīng)實(shí)現(xiàn)工業(yè)3.0，而如今因?yàn)楦黝I(lǐng)域、各行業(yè)自動(dòng)化發(fā)展的現(xiàn)狀不一樣，正處于由制造業(yè)向工業(yè)2.0與工業(yè)3.0的過渡階段，而這個(gè)局面可能會(huì)在未來的很長(zhǎng)一段時(shí)間內(nèi)繼續(xù)。在制造業(yè)、工業(yè)2.0、工業(yè)3.0共存并行，伴隨著制造業(yè)人工成本不斷上漲的局面下，未來3-5年將會(huì)出現(xiàn)一個(gè)大批制造企業(yè)進(jìn)行生產(chǎn)自動(dòng)化改造的現(xiàn)象。而這個(gè)改造浪潮將會(huì)機(jī)器人需求的爆發(fā)，機(jī)器人行業(yè)將會(huì)在未來幾年內(nèi)保持高速增長(zhǎng)的態(tài)勢(shì)
但在進(jìn)步顯著的同時(shí)，工藝水平還不夠高、技術(shù)能力還不夠強(qiáng)依然是大部分“制造”給人們的印象。從大米奶粉到電飯鍋馬桶蓋，游客“走到哪里買到哪里”的消息不絕于耳。而譬如汽車發(fā)動(dòng)機(jī)、飛機(jī)發(fā)動(dòng)機(jī)、攝像頭、電子元器件、芯片等領(lǐng)域的研發(fā)，一直是我們的短板，也使相關(guān)產(chǎn)業(yè)長(zhǎng)期處于產(chǎn)業(yè)鏈低端。據(jù)測(cè)算，生產(chǎn)一部178.96美元的蘋果手機(jī)，負(fù)責(zé)組裝的企業(yè)僅賺得6.5美元?，F(xiàn)實(shí)的尷尬時(shí)時(shí)刻刻提醒我們：在許多領(lǐng)域，“制造”距離水平還有不小差距，還沒有真正取得不可替代的競(jìng)爭(zhēng)優(yōu)勢(shì)。 總體來看，“制造”長(zhǎng)期多以價(jià)格低廉、產(chǎn)量龐大勝出，但放眼，這種“拼量”發(fā)展正面臨“雙向”。一方面，后危機(jī)時(shí)代的發(fā)達(dá)已重新審視實(shí)體經(jīng)濟(jì)，紛紛大舉實(shí)施“再工業(yè)化”，另一方面，其他發(fā)展家在承接產(chǎn)業(yè)及資本轉(zhuǎn)移方面展示了更大成本優(yōu)勢(shì)。反觀國(guó)內(nèi)，隨著消費(fèi)需求升級(jí)，“便宜”已經(jīng)不再是左右人們選擇的指標(biāo)，消費(fèi)潛力大量境外“落地”就是證明。可以說，“制造”想要百尺竿頭，更進(jìn)一步，就不能僅僅停留在模仿和代工，必須緊跟市場(chǎng)，嚴(yán)把品質(zhì)關(guān)和增強(qiáng)創(chuàng)新能力，“做好”“做精”“做強(qiáng)”，抓緊突破核心技術(shù)，躍升到產(chǎn)業(yè)鏈前端，打造出“品牌”。
