Understanding the centr of mas and stability is essential for designing and controling legged robots. Accurate calculations help pe improvite balance, movement relevancy, and safety during operation. This article le provides a practical overview of methods used to determinate these kritický parametrs.

Calculating thee Centr of Mass

Te center of mass (CoM) is thes point where thee mass of the robot is consided to o be concluated. To calculate it, the robot 's body is divided into segments, and the mass and position of each segment are considered.

Te formula for the CoM in three dimensions is:

kde m 'l1; fl1; FLT: 0' l3; i 'l1; FLT: 1' l3; fl3; is the mass of segment i, and x 'l1; fl1; FLT: 2' l3; i 'l1; FLT: 3' l3; is its position coordinate.

Stability in legged robots depens on then thee position of thee CoM relative to tho thee support polygon - thee area catplesed by thee robot 's contact point with thee ground. A robot is stable if thee projection of it CoM falls with in this polygon.

To evaluate stability, thee following steps are typically taken:

  • Určete, zda je polygon based on contact points.
  • Vypočítejte si to CoM projektion onto thee ground plane.
  • Kontrola if these projection lies with in thee support polygon.

Accurate measurements of mas distribution and contact points are crial. Sensors and modeling software assitt in real-time calculations, adabling dynamic settings to maintain stability during movement.

Regular updates of the CoM and support polygon are necessary when thee robot changes posttura or tails. This ensures reliable stability assessments and safe operation.
