The piston igniation and crankshaft mechanism in a motor vehicle. The piston rotates because of

the fuel ignition that causes the crankshaft to rotate. The rotation, after couple of steps, causes

the motor vehicle to move.

Da Vinci Surgical Arm: Facilitates complex surgery using a minimally invasive approach. The

system has many degrees of freedom and is operated locally by a surgeon from a console. This

device was approved by the FDA in 2000 and has been used extensively in prostatectomies and

increasingly in cardiac valve repairs.

Notes:

Points F, H, J, N, and links 6 and 8 are hidden, but mirror points E, G, I, M, and links 5 and 7.

Link 4 is actually a quatrinary link between points C, D, E, and F.

There’s another at point N, mirroring point M.

Links 5 and 9 cross over one another, but are not a solid link.
