Statement of requirements for Collaborative Robotics

The requirement is for a collaborative robotic arm (cobot) which is designed specifically for human/robot interaction, without the need for protective devices. The cobot will be capable of carrying out repetitive/assistive tasks in an industrial manufacturing SME environment. It will have sufficient sensors on the cobot to ensure that the cobot doesn't cause injury to its human colleagues.

Tasks required to be undertaken include, but are not limited to:

CNC machine loading/tending Testing Inspection Cleaning Packaging Manoeuvring of components Deburring

Specification

The cobot is required to have:

Minimum payload of 10 kgs

Minimum reach of 1300mm

Certifications EN ISO 13849-1, EN ISO 10218-1 and PLd Category 3 Mounting capability within any orientation

End effectors in the form of grippers or similar modules

IP Rating sufficient to be capable of working in contact with CNC cutting fluids Power supply 240V AC 50 Hz UK 3 pin

Teach pendant and appropriate software in order to be able to program Control Box

It is a condition that the item quoted for is collaborative, which means that it must contain torque sensors with such sensitivity to recognise when a human is present during a move, and if collision occurs, the arm will halt.

Quotations submitted must advise the following additional information applicable to the cobot they are offering against:

Degrees of freedom and Number of rotating joints Power supply voltage

Power consumption maximum average Repeatability (defined/measured in +/0mm)

Axis range in degrees & max speeds per second, per joint Noise in dBA
