Project info

Building a robot that walks is an ultimate goal of robotics! Just look at the recent hype on humanoid robots such as Figure 1, Tesla Optimus or Boston Dynamics Atlas. This Rabbit is up to compete with all of them! ….. just kidding.

Building a robot that walks on two legs is a challenging task. It’s no coincidence that only Homo sapiens chose this form of movement. Walking on two legs demands advanced mechanics and computing power to maintain balance.

Our walking rabbit robot simplifies this. At its core, his walking is just a modified version of two-wheel driving, with longer limbs instead of wheels.

Get creative! Customize your robot’s head to resemble any animal or creature.

  2. RED LINES – detailed shapes cut after the black lines
  3. BLUE DASHED LINES – bending lines traced with scissors
