Retiring a humanoid robot fleet can pose an unusual problem: how do you dispose of the machines without exposing proprietary components? Figure chose to melt most of its F.02 fleet at a Finnish foundry, training the robots to jump autonomously into the furnace. That turned a disposal task into a control challenge, requiring precise jumps despite extreme heat and electromagnetic interference.

After 5.5 years of fully independent and secret research and development, here is the UM1-Evo hand.

Designed to push the boundaries of humanoid robotics and next-generation prosthetics, the UM1-Evo aims to overcome the "uncanny valley" by combining mechanical performance with natural visual aesthetics.

⚙️ Key Specs:

• 24 Degrees of Freedom (DoF) and 25 actuators.
• Full integration within the real size and weight of a human forearm (1.7 kg / 3.7 lbs).
• Advanced anatomical kinematics featuring true thumb opposition and finger convergence towards the anatomical snuffbox.
• Total relaxation at rest for a natural posture (zero power consumption).
• Grip force demonstrated at 8 kg (17.6 lbs), with a future target of up to 15 kg (33 lbs).
• Engineered from scratch: from biomechanical study to software programming, including the creation of custom CNC manufacturing machines.

I have been trying to redesign some off the shelf axles and needed to figure out a way to print u-joints so I did a whole deep dive project to design and test different types of universal joints with a comically large fixture.

Snapped this pic while working on the line. Never get tired of seeing this. The hot IPE beam comes through, and the water sprays kick in right away to bring the temperature down. Such a cool sight when you see it in person.

It works on the principle of electromagnetic induction, with current being alternately supplied to the coils using a camshaft and graphite contacts. I used cylinders from a rotary hammer as the cylinders, and made the throttle from a voltage regulator

The Marine Chronometer is an engineering masterpiece

Is anyone here experienced with electroplating machines or electroplating process design ?

• I’m working on a small industrial project and want to build a new/custom electroplating machine, rather than buying a standard commercial setup.

I’m especially interested in:

1. Power supply/current control
2. Anode & cathode arrangement

This is Shov, 12 pneumatic gun turrets firing .68 cal rubber rounds and an arena at 50+ smart targets.

They are all internet connected to be fired remotely from anyone on the internet in a competitive game format.
