A mobile robot that revs up indus­trial pro­duc­tion: SOTO enables effi­cient auto­mated line feed­ing, for exam­ple in the auto­mo­tive industry. 


Fac­tory 4.0 becomes more real: SOTO brings mate­ri­als to the assem­bly line, just-in-time and com­pletely autonomously. SOTO inter­acts flex­i­bly with a dynamic envi­ron­ment and changes can be eas­ily adapted.



SOTO helps to keep inven­tory lev­els low and deliv­ers replen­ish­ment exactly when it is needed. It works up to 20 hours per day – for processes that are not only more effi­cient but also sig­nif­i­cantly cheaper. 


The intel­li­gent robot SOTO inte­grates seam­lessly into the Fac­tory 4.0. It can be flex­i­bly con­fig­ured, relieves the employ­ees and works safely and effi­ciently along­side machines, vehi­cles and peo­ple – for opti­mum pro­duc­tion planning.


Pro­duc­tion logis­tics becomes smart: with sen­sors, 3D cam­eras and the intel­li­gent ACROS​.AI oper­at­ing sys­tem, SOTO can per­ceive its envi­ron­ment, react intel­li­gently to changes and even learn from experience.


Changes in the lay­out, han­dover sta­tions, traf­fic rules, etc. are com­mon in a dynamic envi­ron­ment like an assem­bly line. There­fore, the sys­tem can be eas­ily adapted by yourself.


The autonomous sup­ply chain robot SOTO is ideal for indus­trial and pro­duc­tion processes. Thanks to its intel­li­gent soft­ware, it can react flex­i­bly to chang­ing require­ments, com­pletely replace pick carts and tug­ger trains, or inter­act use­fully with them. It deals with an increas­ing num­ber of prod­ucts using a clever grip­per sys­tem that can han­dle dif­fer­ent totes in dif­fer­ent posi­tions and heights. These are its most impor­tant tech­no­log­i­cal fea­tures at a glance:

Handling totes - with even more variety

SOTO can grasp totes with a weight of up to 20 kg and a maximum size of 600 x 400 x 320 mm (L x W x H). The pickup and put down from the robot can be done to the right, left or to the front.

The most flexible gripper

The rotating gripper from SOTO allows to turn totes of different sizes by 90° or 180° - inside the robot. This means for example, full totes can be put down into a shelf on the long side and empties can be picked up again on the short side. The gripper is also flexible in terms of height: the transfer takes place at heights between 40 cm and 160 cm above ground.

High transport capacity

Depending on their size, SOTO can store between 8 and 24 totes in its backpack at once. By storing up to two totes behind each other, SOTO utilizes the existing storage space most efficiently.

Omnidirectional drive base

SOTO can steer its drive wheels individually and therefore drive in any direction without cornering. Precise maneuvering is possible even in the tightest of spaces. This enables the robot for example, to "dock" to the side of a shelf without prior maneuvering.

Safe navigation

Certified laser scanners at the front and rear enable SOTO to navigate freely at up to 1.5 m/s. They also guarantee safe operation parallel to people and vehicles. Depending on how close an obstacle comes, SOTO reduces its speed until it stops or looks for an alternative route.

3D obstacle avoidance

Some obstacles cannot be detected on laser scanner height. 3D scanners monitor the space in the front and back of SOTO to safely avoid all other obstacles.

Transfer systems

Flow rack

Flow rack

SOTO inter­acts with adapted flow racks to put down totes or to pick up totes. 

Conveyor belt

The con­veyor belt acts as an inter­face between SOTO and exist­ing automa­tion infrastructure.

Tugger train
