1. ENERGY-SAVING BY DESIGN Optimising energy efficiency is one of the most effective ways to make robots more sustainable. In high-speed manufacturing, even marginal reductions in power usage can translate into significant savings over time. One way robotics engineers are tackling this is by refining how robots move. Shibaura Machine took this approach when designing its latest series of SCARA robots, the THE800 and THE1000. Advanced motion control algorithms were created by engineers to fine-tune acceleration and deceleration, reducing unnecessary energy spikes while keeping operations smooth and precise. The principle is simple but powerful: move smarter, use less energy. Weight is another major factor. Heavier robots require more power to move, so reducing mass is a straightforward way to improve efficiency. With this in mind, Shibaura Machine designed the THE800 to be 30 kg lighter than its predecessor, the TH850A, without compromising strength. Less weight means less power needed to get the job done — a win-win for both sustainability and performance. Optimising torque performance is another important consideration. Shibaura Machine used a simulation process to accurately predict torque fluctuations of the THE800 model during various stages of motion. The study identified areas where efficiency could be improved, leading to enhanced motor control and smoother motion profiles. The findings

ENGINEERED FOR SUSTAINABILITY: THE NEW BLUEPRINT FOR ROBOT DESIGN
In the world of robot manufacturing, efficiency has always been king. Faster cycle times, greater precision and maximum output have long dictated how industrial robots are designed. But today, a new measure of success is emerging: sustainability. Here, Nigel Smith, managing director of TM Robotics, explores three key factors shaping sustainable robot design.
demonstrated how adjusting acceleration and deceleration curves could minimise unnecessary torque peaks, reducing mechanical stress and improving overall efficiency.
2. REIMAGINING ROBOT MATERIALS Sustainability in robotics is not just about energy use, it starts at the very first stage of design. That means carefully considering the materials used in construction.
