Just lately, there was a broadly publicized incident the place a chess robotic system broke the finger of a seven-year-old little one at a event in Moscow. This could by no means have occurred. The robotic was not certainly one of our cobots, however we do really feel compelled to remark as a result of this robotic chess utility does NOT mirror regular security requirements and well-accepted practices throughout the robotics sector.
The best way this incident was reported can distort understanding of robotics utility security. An official of the Russian chess federation implied that the incident occurred as a result of the kid ‘violated’ security guidelines. That is totally unreasonable!
Robotic system integrators ought to carry out a threat evaluation
It’s globally accepted that robotic system integrator ought to carry out a threat evaluation for the meant use and readily foreseeable misuses. If this had been performed, quite a few modifications would have been carried out together with a smooth gripper as a substitute of 1 with laborious edges and the usage of security sensors solely permitting motion when nobody was close by. It was fairly foreseeable that the human chess participant can be concentrating on the sport, not their robotic opponent.
Automation security is about “making the simple technique to work, the protected technique to work”. On this case, all chess motions want to have the ability to be carried out with no particular person needing to suppose “am I okay to maneuver my chess piece or will I be injured?”.
The know-how exists to stop incidents like this from taking place
Energy and power restricted (PFL) collaborative robots (cobots) would cease transferring after contact with an individual. Expertise of this kind is available. Following the appliance threat evaluation’s necessities, tens of hundreds of cobots are working safely alongside people on daily basis. In reality, cobots are more and more utilized in training settings to show programming and the event of robotic purposes.
Security requirements are established internationally and independently licensed
All respected robotic producers and integrators embrace their accountability of delivering protected merchandise and options. At Common Robots, our e-Collection robots are licensed to EN ISO 13849-1 and EN ISO 10218-1 by TÜV Nord. The cobots embrace 17 superior configurable security features licensed by TÜV Nord as PLd Cat 3. This implies they’ve configurable stopping time and stopping distance, joint place limits, pose restrict, device orientation restrict, security planes, security boundaries, protected dwelling, power limiting (TCP) and elbow security (power, velocity, boundary restriction).
The protected deployment of cobots can carry enormous societal advantages
This chess taking part in robotic integrator displays badly upon the hundreds of automation professionals that take security very severely. The world continues to face labor shortages. Robotics and automation can present a vital and well timed answer and may make workplaces significantly better environments for people to work in. However these alternatives will solely be absolutely realized when security is a precedence in utility deployment.
