MR DIY launches warehouse with RM5m robotic e-commerce system MR DIY Group (M) Bhd (Malaysia) has launched an e-commerce warehouse in Seri Kembangan, Selangor. In a statement today, the group said it had invested up to RM5 million to design and build a system that aims to boost the speed of its online order processes. The home improvement retailer said the newly launched warehouse in Seri Kembangan is equipped with the system. The 65,000 square feet warehouse is equipped with programmable robots that are able to fulfil online purchases faster compared to a manual system, resulting in a 200% increase in operational efficiency, it said. The group's vice president of marketing Andy Chin said MR DIY had already started the design and construction of the warehouse in 2019, to adopt Fourth Industrial Revolution (IR4.0) technologies and address the online shopping trend, which has been gaining traction in recent years. 3 With the advent of the pandemic and the resulting movement control orders, online shopping grew in quantum leaps and has become a behaviour that is here to stay, he added. He also said the warehouse enables the group to process online orders at triple the previous rate, meaning customers can look forward to receiving their orders faster. Its automated selection functions reduce the possibility of human error, and its innovative design enables the warehouse to stock a wider variety of products, giving our customers a broader choice of more than 20,000 products online. The higher level of automated tasks has also reduced the need for physical labour for repetitive processes and given us the opportunity to upskill our warehouse employees in robotics and automation, leading to opportunities in supervisory and management roles. All in, it is about driving growth, delivering value and growing talent, he added.
