Brandon Lai wants to build a humanoid robot. He started with the upper body and quickly realized that off-the-shelf actuators would either cost too much or limit what the machine could do. So he set out to design and build his own. This latest version marks his second serious attempt, and it already produces usable torque in testing. He focused on a shoulder actuator sized for a roughly four-kilogram arm about half a meter long. The targets were straightforward. Peak torque needed to reach around 20 newton-meters. Output speed should fall between 40 and 60 revolutions per minute. The unit also had to run continuously for more than an hour. Keeping the cost near $150 per actuator would make it practical for other builders to copy or adapt.

Almond Robotics launched Axol this week as a dual-arm robot built specifically for teams developing physical AI systems that must function in factories, warehouses, kitchens, and other unpredictable settings. The company spent the past year putting existing robots through real shifts in grocery stores and production lines. Those machines repeatedly hit limits that slowed progress or caused outright failures.

Deep Robotics sent a modified version of its compact Lynx S10 robot on a research vessel bound for the Arctic Ocean. The goal was straightforward. Engineers wanted to see how the small machine would handle real polar conditions that humans approach with extreme caution. The prototype completed its mission and became the first quadruped robot to step onto Arctic Ocean ice floes.

UBTECH spent years refining full-size humanoids for factory floors and warehouse aisles. Those machines learned to move with care around people, handle precise assembly steps, and stay safe in busy production lines at places like NIO and FAW-Volkswagen plants. Now the same engineering team has turned that foundation toward regular homes through a new consumer brand called UWORLD and its first offering, the U1 series.
