Look how a robot with a jet wheel balances itself on the surface

Researchers from the Rhine-Westphalian Technical University in Achen, with the participation of Sebastian Trimpa, and members of the Max Planck Institute of Intellectual Systems in Stuttgart, have recently developed Weelbot. It is a single-wheeled bicycle with a symmetrical jet wheel. It stands on the wheel autonomously from any original position.

Engineers have developed a minimalistic one-wheeled Wheelbot so that robotic technicians and computer technicians can use it as a test bench across the board.

Single-wheeled robots that integrate jet wheels are intuitively understandable design, easy to assemble for both experienced engineers and students. Despite their simplicity, such vehicles with a jet wheel are difficult to control, so they are suitable for developing advanced learning-based management techniques.

Shelbot is equipped with a design that prevents it from overturning in its longitudinal motion. However, unlike single-wheeled bicycles, the robot is equipped with a jet wheel that prevents it from overturning in the lateral direction.

When the current is used at 16 Amper, the engine that drives Weelbot reaches the limit speed in only 0.25 seconds. Given this, engineers have developed a completely new design for the robot. They have decided that the robot should be symmetrical, which effectively reduces the number of different parts that need to be printed. In the end, Weelbot uses any of its wheels as rotating.

Symmetry has another advantage: the upper wheel has to be significantly smaller than the existing single-wheeled robots, which reduces its inertia in the direction of yaw, and engineers have designed the robot in such a way as to minimize the required torque for self-balancing.
