* d₁, d₂ and ₂ are the
joint variables
For the robot above, please determine K3 (the kinetic energy of Link #3)
K3 = 1/2 (d ₂ ) ² + ²/2 (03) ²
© K3 = ½ (d₁ ) ² + ½ (d₂ ) ² + ½ (03) ²
K3 = ½ (di + d₂ ) ² + ³2 (03) ²
K3 = ½ (d₁ + d₂ ) ² + ½ (03) ²
m₂ = m₁ = m₂ = M₁₂ = 1 kg
The moment of inertia of
the last link is 3 kg. m².
The mass centers are located
on the middle point of each link.
