Why is nobody talking about this?
ToddlerBot is a 0.56 m, 3.4 kg humanoid robot built at Stanford by Haochen Shi, Weizhuo Wang, Shuran Song and C. Karen Liu. Its goal is to make robot learning cheap and easy to reproduce. The full hardware costs under 6,000 USD.
Hardware
- 30 active degrees of freedom: 7 per arm, 6 per leg, 2 in the neck, 2 in the waist
- Dynamixel servos (XC330, XC430, 2XC430, 2XL430 and XM430 in the current open-source configuration)
- 3D-printed structure: a full repair takes about 21 minutes of printing and 14 minutes of assembly
- Jetson Orin NX 16 GB, two fisheye cameras, an IMU, two microphones and a speaker
Sim-to-real
- Zero-point calibration and motor system identification produce a digital twin of the robot
- Walking: an RL policy trained in MuJoCo MJX and transferred to the real robot with no extra training, up to 0.25 m/s in any direction and 1 rad/s in place
- Push-ups and pull-ups: keyframed motions, also transferred with no extra training
Manipulation
- RGB diffusion policies trained on 60 teleoperated demonstrations per task
- Real-time onboard depth estimation at 10 Hz from the stereo fisheye cameras
- A policy trained on one robot runs on another, and two robots tidied a room together
Measured limits
- Payload: 1,484 g, about 40% of its body weight
- Endurance: 19 minutes of walking before motor heating affects stability
- Durability: up to 7 falls before a part breaks
- The cartwheel works, but its success rate is still low
This might be one of the most minimalist snake robots ever built.
• One motor.
• No dozens of actuated joints.
• Crawls, climbs between walls and swims.
It's called SAW (Single Actuator Wave-like robot), developed by Dr. David Zarrouk's Bio-Inspired and Medical Robotics Lab at Ben-Gurion University of the Negev.
How it works
• A single motor rotates a helix inside the robot's body.
• 3D-printed links follow the helix to create a continuous wave.
• The links push against the surrounding surface to propel the robot.
• Front wheels handle steering.
The numbers
• 57 cm/s on flat ground
• Around 5× faster than similar wave robots
• Around 8 cm/s in a tunnel, with contact against both walls
• Around 6 cm/s while swimming in its waterproof version
One gait, multiple environments
• Gravel, sand and grass
• Obstacles and narrow passages
• Pipes, tunnels and water
The same wave-like motion works across these environments without changing the gait.
Why use one motor?
Traditional snake robots often rely on 10, 20 or 30 motors. SAW uses a single actuator, reducing the number of moving parts and making the design lighter, simpler to manufacture and suitable for 3D printing.
Possible applications
• Search and rescue in collapsed buildings
• Inspection of pipes and tunnels
• Medical imaging and biopsies inside the digestive tract, with a miniaturized version around 1 cm wide or less
The research was published in Bioinspiration & Biomimetics under the title Single actuator wavelike robot (SAW): design modeling, and experiments.
What caught my attention is how the helical mechanism generates the motion with just one motor. The mechanical design does most of the work

Elon on Q3 earnings call, setting expectations correctly for the Optimus ramp:
We’ve started early production on the high-volume line. The initial part of the S-curve is bumpy, so it will be slow. The vast majority of the 1-million-unit line equipment has landed in Fremont.
A lot of work remains to be done on the AI for the robot. He expects AI and hardware reliability issues to be solved by the end of next year.
He believes no one is close to Tesla in general-purpose humanoids.
Tesla's Q3 earnings deck:
"Optimus production began in Fremont on our high-volume lines.
The bots coming off this line are the first production-quality bots that we have manufactured. While we will continue to iterate on the hardware and manufacturing process, we have proven that the current manufacturing process for Optimus is suitable for a commercial product."

Most people just saw a humanoid robot throwing kicks and flipping off cars. But the H2-X has some technical details worth looking at.
Here’s what the footage and the available specifications tell us about Unitree’s Kung Fu Legend Guardian.
▪️ Height: approximately 170 cm, according to the H2-X booth panel.
▪️ Weight: approximately 65 kg, according to the same panel.
▪️ Degrees of freedom: 31, covering the robot’s articulated body.
▪️ Joint layout: 6 DOF per leg, 7 per arm, 3 at the waist and 2 at the head.
This breakdown is reported for the H2 and has not been independently confirmed for the H2-X.
▪️ Battery endurance: Unitree advertises approximately 8 hours. The operating conditions and runtime during intense movement have not been published.
▪️ Battery design: two battery modules are visible on the robot’s back. Their capacity has not been disclosed.
▪️ Joint torque: figures of up to 360 N·m for the legs and 120 N·m for the arms are associated with the H2. They are not confirmed H2-X specifications.
▪️ Computing power: up to 2,070 TOPS is reported for a high-end H2 configuration. Its use in the H2-X remains unconfirmed.
▪️ Sensors: binocular wide-angle vision, an inertial measurement unit and joint sensors are listed for the H2. The H2-X sensor package has not been fully documented.
▪️ Speed and payload: figures below 2 m/s, 7 kg continuous payload and 21 kg short-duration payload are reported for the H2, not confirmed H2-X ratings.
▪️ Recovery: the demonstration shows the robot getting back up after a vehicle runs over it. No standardized recovery test results have been published.
▪️ Autonomy: no detailed explanation of teleoperation, preprogrammed sequences or onboard decision-making has been released.
One detail deserves attention: the booth lists the H2-X at around 170 cm and 65 kg, while many reports quote 182 cm and 70 kg from the older H2.
The distinction matters when comparing the hardware.
Unitree has yet to publish a complete H2-X datasheet covering torque, computing hardware, payload, battery capacity and autonomous operation.
Which specification would you want Unitree to publish first?

The things yet to be discovered are limitless. Never let anyone convince you that any space is too crowded to enter. There is always something new to build, explore, and create.

Unitree H2 is like superhero
Fending off an intruder armed with a knife
Lifting a car to rescue someone trapped underneath
Pushing a pedestrian out of the path of an oncoming vehicle
…
In a chaotic and complex real world,
Humanoid robots are needed to protect humanity…

You can build an 8-servo robotic hand for under €200 in parts.
The AmazingHand by Pollen Robotics has two options:
DIY: source 8 Feetech SCS0009 servos, print the mechanical structure in 3D and assemble the linkages using the free GitHub files.
Seeed Studio kit around $89, or €119.43 including VAT at RobotShop Europe. It includes the structure, 8 servos, a XIAO-compatible control board, power supply, cables and hardware.
Both require assembly. The DIY route gives you the parts list and printable design. The kit bundles the components.
Which route would you take to build your own robotic hand?
