Pick and Place with 2D Cameras

Robot-​supported pick and place is wi­de­ly used in ma­nu­fac­tu­ring, as­sem­bly and pac­ka­ging pro­ces­ses where ob­jec­ts must be ac­cu­ra­te­ly de­tec­ted for fur­ther pro­ces­sing, pic­ked and then pla­ced in a dif­fe­rent po­si­tion. Ob­ject lo­ca­li­za­tion is car­ried out via 2D ca­me­ras, which send the po­si­tion data di­rec­tly to the robot.

Fle­xi­ble Ca­me­ra Moun­ting Op­tions

No two ap­pli­ca­tions are the same! Ma­chi­ne vi­sion hard­ware can be moun­ted sta­ti­cal­ly above the grip­ping area or di­rec­tly on the robot arm de­pen­ding on the ap­pli­ca­tion. Sta­tic moun­ting of the ca­me­ras is par­ti­cu­lar­ly sui­ta­ble for space-​critical ap­pli­ca­tions or small robot arms with li­mi­ted in­stal­la­tion space, while the po­si­tio­ning of the ca­me­ra on the robot arm in­crea­ses the fle­xi­bi­li­ty of the ap­pli­ca­tion.

Di­rect Com­mu­ni­ca­tion bet­ween Ca­me­ra and Robot

The 2D ca­me­ra com­mu­ni­ca­tes di­rec­tly with ro­bo­ts from the ma­nu­fac­tu­rers UR, KUKA, and ABB via the Ro­bo­tic Vi­sion in­ter­fa­ce – there is no need to de­ve­lop a se­pa­ra­te in­ter­fa­ce or con­nect any se­pa­ra­te hard­ware. Sam­ple pro­grams or an URCap for UR can be do­wn­loa­ded for each robot type. This makes it very easy and quick to set up the Robot Vi­sion ap­pli­ca­tion – re­gard­less of whe­ther you are using a B60 smart ca­me­ra or a ma­chi­ne vi­sion con­trol­ler with ma­chi­ne vi­sion ca­me­ra. The do­cu­men­ted TCP/IP com­mu­ni­ca­tion al­lo­ws for con­nec­tion with other ma­nu­fac­tu­rers.
 

Seam­less In­te­gra­tion into the uni­Vi­sion Eco­sy­stem

The wen­glor uni­Vi­sion 3 tool­box of­fers va­rious mo­du­les for ob­ject de­tec­tion, such as the mo­du­les for lo­ca­li­za­tion and pat­tern mat­ching. Both mo­du­les ena­ble dif­fe­rent ob­ject types to be taught in, whe­re­by se­ve­ral – even dif­fe­rent – ob­jec­ts can be found in both mo­du­les and sor­ted, for exam­ple, by po­si­tion. Va­ria­ble off­se­ts in x and y can also be im­ple­men­ted, which in­crea­ses the fle­xi­bi­li­ty of the pick-​and-place ap­pli­ca­tion enor­mou­sly: De­pen­ding on the ap­pli­ca­tion, it is thus pos­si­ble to spe­ci­fy the exact point at which the robot should grab the ob­ject – at the tip, in the midd­le or ra­ther at the rear. The re­sul­ts, such as the grip­ping po­si­tion or the con­tour of the de­tec­ted ob­ject, can be di­splayed in­di­vi­dual­ly and fle­xi­bly in the web-​based vi­sua­li­za­tion.

Re­du­ced Cycle Times Thanks to Multi-​Object Re­cor­ding

In wen­glor uni­Vi­sion 3 soft­ware, se­ve­ral – even dif­fe­rent – ob­jec­ts can be de­tec­ted with a sin­gle image cap­tu­re and their coor­di­na­tes can be pas­sed on to the robot con­trol sy­stem. This means that the robot can grip the ob­jec­ts di­rec­tly one after the other wi­thout ha­ving to move to the de­tec­tion po­si­tion for ca­me­ra cap­tu­re again be­fo­re each grip. This re­du­ces cycle time and grea­tly in­crea­ses the ef­fi­cien­cy of the pick-​and-place ap­pli­ca­tion. 

Pre­ci­se Ca­li­bra­tion with Ac­cu­ra­te Ca­li­bra­tion Tar­ge­ts

The 2D ca­me­ra and robot must ini­tial­ly be ca­li­bra­ted once. Hi­ghly ac­cu­ra­te ca­li­bra­tion tar­ge­ts are avai­la­ble in va­rious sizes and ma­te­rials (glass for tran­smit­ted light ap­pli­ca­tions, car­bon fiber for in­ci­dent light ap­pli­ca­tions). The suc­ces­sful ca­li­bra­tion pro­cess can be chec­ked di­rec­tly via a ve­ri­fi­ca­tion step.

取放与无序抓取具有什么区别?

取放:精确定位和抓取

在取放应用中,2D 摄像头可对待抓取的物体进行定位,并将其位置坐标发给机器人控制系统。如此能使机器人精确抓取物体,然后放到另一位置。
取放功能适用于简单、快速的应用,在此类应用中物体是分散的且位于同一层。 
 

无序抓取:从箱内取物

无序抓取是指机器人从箱子中取出任意摆放的物体的自动化应用。为此,需要 3D 传感器来识别物体在空间中的位置,并传送给机器人。
使用 3D 传感器进行的无序抓取适用于物体未分散并位于任意位置的场合。
