Vibrating poured concrete is a game-changer. It eliminates air pockets that create weak spots, cracks, and honeycombing. Small step, huge difference in quality and durability for driveways, slabs, or foundations. Pro move every serious builder uses.

This work makes a humanoid robot do simple parkour moves by looking with a depth camera and choosing the right move on the fly. The big deal is that it turns lots of small human moves into long, real-time robot behavior, without hand-coding every transition or retraining for each new course. A humanoid robot is usually good at steady walking, but it often fails when it has to do fast moves like jumping up, vaulting, or rolling, and then keep going to the next obstacle. The hard part is that you cannot easily collect training data for every possible obstacle shape, distance, and mistake, so robots end up learning a few moves that only work in a narrow setup. This work starts from short clips of real human parkour moves, like stepping over, vaulting, climbing, and rolling. It uses motion matching, which is basically a smart “pick the next clip that fits best right now” search, to stitch those short clips into a long, smooth plan that looks like a human doing a whole course. Then it trains a controller with reinforcement learning (RL), which means the robot learns by trial and error to copy that plan while staying balanced and not falling. After training separate expert controllers for different moves, it compresses them into 1 controller that uses only onboard depth sensing and a simple “go this fast in this direction” command. In real tests on a Unitree G1 humanoid, it can clear multiple obstacles in a row, adapt when obstacles get moved, and climb a wall up to 1.25m.

The moisture question always comes up when I post pics of my indoor pools on my new builds. Step by step below on how I control it. We create a room where moisture can’t escape into other areas of the home while also having a mechanical system in place to pull the moisture out of the air so mildew/mold don’t ever develop in the pool room itself. In the STR space, investors are trying to stand out. Pools rent. Indoor pools rent even better. You can swim in the winter or summer. 1) Pool is always built on lowest floor inside (generally basement structure) 2) Concrete block wall for basement with very little wood frame 3) Densglass (kind of like a moisture resistant drywall) attached to concrete block 4) Special stucco just like you see on exterior of homes sprayed onto Densglass. The stucco is dyed to color of my choice. 5) Industrial grade dehumidifier (I use Santa Fe or Watchdog Brand). The humidity pulled from air is pumped back into the pool system near the mechanical room or outside. 6) Mini split for the pool room. Main floor HVAC covers the sleeping rooms, bathroom of basement and is always separated from pool room. You don’t want chlorinated air running through a main HVAC system. I look at having to replace the minisplit & dehumidifier about every 4 to 5 yrs because of the chlorinated air that goes through them. 7) Exhaust Fan leading to exterior which also pulls humid air out of the room as a supplemental support for the dehumidifier. When overhead lights are turned on, we have it so the exhaust fan kicks on as well. That’s it. We create a “bubble”, where no moisture gets into the other areas of home and the humid air gets pulled from the pool room.
