DSPOWER yakatanga muna 2013 uye mugadziri akatarisana nekutsvaga nekusimudzira, kugadzira uye dzidzo yemarobhoti servos,akangwara marobhoti servos, drone servos, uye zvimwe zvine hukama.
Kubva pakuvambwa kwayo, takatarisana nezvinodiwa zvemarobhoti uye drone servos, uye akagadzira uye akagadzira servo zvigadzirwa zvakakodzera vashandisi vemarobhoti.
Nhasi, tichagovana zvedu marobhoti ruoko mhinduro.
Ruoko rwerobhoti runoita kutonga kwekufamba, sekupinza mweya mukati mesimbi skeleton, uye servo ndiye mutungamiriri akanyatsojeka. Mumusangano weDSPOWER weR&D, zuva rega rega tinogona kuona izvo zvikamu zvichishandurwa kubva kudhirowa kuita vanotamba mitambo.
Nhasi, ndinoda kukuudza kuti servo inoita sei kuti robhoti ruoko rushande seruwoko rwemunhu, izvo zvinosanganisira ese magiya chaiwo meshing nemumwe uye kuronga kwakangwara.
Sei Servo Inodzora Iyo Angle yeRobotic Arm
Iyo servo inosanganisira yakanyanya hungwaru mhinduro system. A potentiometer inotarisisa nzvimbo yeshaft yekubuda munguva chaiyo kana yagamuchira chiratidzo chekudzora. Mushure mekuenzanisa chinzvimbo ichi nechinzvimbo chakatarwa, chinobva chagadzirisa kutenderera kwemota.
Izvi zvakafanana nekubata chinhu neruoko wakavhara maziso ako, apo zvigunwe zvako zvinoramba zvichigadzirisa zvishoma kusvika pakunyatsomira kwaitwa. Iyo servo yatakagadzira zvine hungwaru yekuchenesa marobhoti inoshandisa TTL serial kutaurirana, zvichiita kuti mubatanidzwa wega wega utaure zvakazvimirira data renzvimbo.Izvi zvinovimbisa kuti kana ruoko rwerobhoti rukaramba rwuri pa-pre-set angle, kukanganisa kuri pasi pe0.5 degrees.
Mumashandisirwo anoshanda, mubatanidzwa wega wega mune robhoti ruoko unofanirwa kurongeka pamakona akasiyana. Semuenzaniso, kana uchibata kapu yakarereka, wrist servo inofanirwa kubhadhara 15 degree tilt, nepo servo yepafudzi inochengetedza 30 madhigirii ekutsigirwa.
Uku kurongeka kwemakona akawanda kunoda kuti servos ipindure nekukurumidza. Isu tinoshandisa simbi giya sisitimu inogona kuchengetedza chinzvimbo kunyangwe pasi pe85 kgf.cm ye torque, sekuwedzera mhasuru dzisingaite kuneta kuruoko rwerobhoti.
Sei zvakakosha kuti maservos akawanda ashande pamwechete?
Servo imwe chete inogona kungowana maswings akareruka, asi ruoko rwerobhoti runofanira kushanda nekupedzisira fluidity yeruoko rwemunhu. Fungidzira wakabata chinyoreso uye kunyora; chiito ichi chinoda kufamba kwakarongeka kwechanza, gokora, uye bendekete.
Mune mashanu axis robotic vacuum cleaner yakagadziriswa nemumwe wedu, nhanho yepamberi yakabatana servos inotakura mutoro, iyo yepakati nhanho yakabatana servos inodzora kufamba kwekuwedzera, uye yekupedzisira nhanho servos inoita mafambiro akanaka. Kupatsanurwa kwebasa uku kwakafanana nenziyo dzesymphony orchestral ensemble pakati pezviridzwa zvakasiyana.
Mune yakawanda servo system, kutonga nguva kunonyanya kukosha. Takamboita nyaya apa robhoti ruoko rwakaita manyawi akabata zai. Takazoona kuti izvi zvakakonzerwa nekunonoka kwegumi millisecond mukupindura kwechiwoko nemunwe servos. Nekuvandudza kugoverwa kwechiratidzo chePWM, takakwanisa kuwana kuwiriraniswa kwese maservos, sekwaya yakadzidziswa. Ikozvino, sisitimu iyi inogona kubata zai mbishi pasina kuripwanya.
Ko servo torque inokanganisa sei ruoko rwerobhoti?
Izvi zvakafanana nekunzwa kunoita ruoko rwemunhu rwuchidedera.
Zvisinei, torque yakakwirira haisi nguva dzose iri nani. Yakawandisa torque inowedzera kushandiswa kwesimba uye zvakare inogona kutungamira kune yakakura zvimiro. Iwo masevhisi atakagadzira edesktop marobhoti anogonazadzisa mabasa akapfava ane torque ye6.3 kgf.cm. Kiyi ndeyekufananidza torque kune zvinorema zvinodikanwa zverobhoti ruoko, senge pakusarudza injini yemotokari, haufanirwe kugara uchitsvaga yakakwira bhiza.
Maitiro ekusarudza Robotic Arm Servo Model
Paunenge uchisarudza servo modhi, funga nezve marobhoti ekushanda mamiriro. Kune maapplication anoda kazhinji kutanga uye kumira, dhijitari servo ine brake basa inokurudzirwa. Imwe nyaya yemutengi yatakasangana nayo yaisanganisira otomatiki mutsara wekugadzira waida iyorobhoti ruoko kuti uwane makumi maviri chaiwo kumira paminiti. Yakajairwa analog servos yaizotambura kubva mukuwedzeredza zvikanganiso, nepo dijitari servos, ine yavo yepamusoro yekuzorodza mwero, inogadzirisa zvakakwana dambudziko iri.
Kufananidza zviyero zvakakosha zvakare. Munguva yakapfuura, vamwe vatengi vakaisa servos yakajairwa mune compact robhoti maoko, zvichikonzera kushata kwekupisa. Isu takazogadzira yakanyatso gadzirwa 26mm gripper servo, iri 40% idiki tichichengetedza torque ye3 kg·cm. Zvakafanana nokusona mbatya dzeruoko rwerobhoti—zvinoda kubvumira kufamba kwakasununguka pasina kunyanyorembera.
Ndeipi misiyano mune servo control protocol?
Iyo PWM protocol, yakafanana neye beat-beat conductor, inotumira mirairo kuburikidza nepulse wide, nepo TTL serial protocol, senge hurukuro, inogona kufambisa mamwe maparamita akaomarara. MuDSPOWER lab, isu tinowanzo enzanisa aya maviri maprotocol.
PWM inokodzera nzvimbo yakapusa yekunongedza kutonga, sekubatidza kana kudzima mwenje, ukuTTL inogona panguva imwe chete kuwana akawanda mhinduro masaini, zvakadai senzvimbo, tembiricha, uye ikozvino.
Parizvino, akawanda uye akawanda maoko emarobhoti ari kutora mahybrid protocol, senge bionic robotic ruoko chirongwa. Mafambiro ekutanga anoshandisa PWM kutonga kuti ave nechokwadi chekuita-chaiyo-nguva, ukuwo kugadzirisa kwakanaka neTTL kunotumira akadzama paramita.
Izvi zvakafanana nekutyaira mota, kwaunoda kushandisa mapedal kudzora kumhanya uye dashboard kutarisa chimiro. Iyi inochinjika gadziriso inobvumira maoko emarobhoti kuchinjika kune ari kuwedzera kuoma nharaunda yekushanda.
Maitiro eKuvandudza Servo Kudzora Kurongeka
Kuvandudza kurongeka kunoda zvese zviri zviviri Hardware uye software. Mune Hardware, isu tinoshandisa 0.1mm chaiyo muchina magiya kudzikisa kutapurirana backlash. Mutengi akashumainopfuurira 2mm inozununguka pamagumo erobhoti ruoko. Mushure mekuferefeta, takaona kuti izvi zvakakonzerwa negear meshing backlash.
Nekutsiva magiya ane helical gear chimiro, nyaya yakagadziriswa. Izvi zvakafanana nekufamba kwewachi: iko kurongeka kwegiya rega rega kunokanganisa kuchengetwa kwenguva.
Yakakosha zvakaenzana isoftware. Yedu anti-kuzunungusa sisitimu inofanotaura inertia yekufamba kwerobhoti ruoko uye inoripa iyo pamberi. Somuenzaniso, pakumira kwechimbichimbi, inobudisa chiratidzo chetariro yakadzokera shure kuti ibvise kupfura kukuru kunokonzerwa nokusadzikama, kungofanana nomutyairi ane ruzivo rwokuzviwanira anotsika mabhureki zvinyoronyoro kuti ave nechokwadi chokumira kwakatsetseka, kusina mhinganidzo.
