What is a robotic arm?
A robotic arm is a programmable industrial manipulator that moves on joints, much like a human arm. Using a gripper, vacuum cup or custom tool at its end, it picks, moves, places or processes parts. Industrial robotic arms perform repetitive tasks at the same speed and precision, shift after shift.
A robotic arm does not create value on the shop floor by itself: it needs a robot cell in which it works with conveyors, sensors, safety fencing, a vision system and PLCs, plus software that connects the cell to production systems. ORELSIS designs, installs and connects the whole system.
Robotic arm applications
- Pick & place: picking parts from conveyors, bins or fixtures and placing them.
- Palletising and depalletising: stacking cases, bags and crates onto pallets by pattern.
- Machine tending: loading and unloading CNC, press and injection-moulding machines.
- Packaging and end-of-line automation: boxing, labelling and shipping preparation.
- Vision-guided quality control: rejecting and recording defective products with cameras.
How does a robotic automation project run?
A robotic automation project starts with an on-site analysis of the task: cycle time, part variety, weight and safety requirements. Then the robot, gripper and cell layout are designed; PLC and robot programs are tested in a virtual cell to shorten on-site commissioning. Finally, the cell is connected to MES, ERP, quality and traceability systems and its performance is monitored live.

What to consider when choosing a robotic arm
- Payload and reach: must match part weight and cell layout.
- Cycle time: must keep up with the line, evaluated together with the gripper and motion profile.
- Repeatability: decisive for precise placement tasks.
- Safety: fencing, area scanners or a collaborative robot (cobot), chosen by risk assessment.
- Integration: the robot controller must talk to PLCs and higher-level systems over standard protocols.
