UR5e Cobot Setup: From Unboxing to First Task

The Universal Robots UR5e is the workhorse of UK manufacturing cobots, offering a 5 kg payload, 850 mm reach, and an intuitive teach pendant that lets operators program tasks without robotics expertise. Whether you have hired a UR5e through roboTED or purchased one outright, this guide walks you through going from sealed box to running your first automated task.

What Arrives in the Box

The UR5e ships in two main packages: the robot arm itself and the control box. You will also receive the teach pendant with its cable, a power cable, mounting bolts, an Allen key set, and the quick-start documentation. If you are hiring through roboTED, your package typically includes an end-effector (gripper or suction cup) matched to your application, plus any mounting brackets required for your workstation.

Mounting the Robot Arm

The UR5e weighs 20.6 kg and can be mounted on a table, floor stand, wall, or ceiling. For most first-time setups, a sturdy workbench or dedicated robot stand is simplest. The base has four M8 bolt holes on a 190 mm diameter circle. Ensure the mounting surface can support the combined weight of the arm plus its maximum payload with a safety factor of at least 10x to prevent vibration during operation.

Position the control box within 4.5 metres of the arm base (the maximum cable length). The control box needs adequate ventilation, so keep a 50 mm clearance on all sides and avoid enclosing it in a sealed cabinet. Connect the robot cable from the arm base to the control box, plug in the teach pendant, and connect the power cable to a standard UK 13A socket.

Initial Power-On and Safety Configuration

When you first power on the UR5e, the teach pendant walks you through a setup wizard. You will configure the language, time zone, and network settings. The critical step is the safety configuration: define the joint limits, speed limits, and force thresholds appropriate for your workspace. For collaborative applications where humans work alongside the robot, UR recommends limiting TCP speed to 250 mm/s and force to 150 N. These can be adjusted later, but starting conservatively prevents incidents during the learning phase.

Programming Your First Pick-and-Place Task

The UR5e uses Polyscope, its graphical programming interface on the teach pendant. For a basic pick-and-place task, follow these steps:

• Create a new programme and add a MoveJ (joint move) waypoint to the home position
• Guide the arm by hand to the pick position and record the waypoint
• Add a gripper close command at the pick position
• Guide the arm to the place position and record that waypoint
• Add a gripper open command at the place position
• Add a MoveJ back to home and set the programme to loop

Test at reduced speed first (10-25%) to verify positions and check for any collision risks. Once satisfied, gradually increase to production speed. The entire process of programming a basic pick-and-place task typically takes 30-60 minutes for a first-time user.

Connecting End-Effectors

The UR5e supports a wide ecosystem of grippers through its tool flange, which provides power (24V, 2A), digital and analogue I/O, and communication interfaces. Popular choices include the Robotiq 2F-85 adaptive gripper for general handling and the OnRobot VGC10 vacuum gripper for flat items. Many UR+ certified end-effectors are plug-and-play with pre-built Polyscope URCaps that add gripper controls directly to the programming interface.

Ongoing Maintenance

The UR5e requires minimal maintenance. Check joint bolts for tightness every 6 months, inspect cables for wear quarterly, and keep the arm clean with a dry cloth. The robot tracks its own joint hours and will notify you when preventive maintenance is recommended, typically at 35,000 operating hours. When you hire through roboTED on a RaaS subscription, all maintenance is included.
