Student productions in the Department of Precision Engineering  covers a wide range of productions from classical manufacturing to the cutting-edge technology. Here we show four moving products from student productions in 2019.

Strandbeest bicycle (Yang Dongxu):
A miniature bicycle based on the kinematic of the strandbeest. Single axis rotation moves its legs as if an animal is walking.

Automaton of stairs (Yuki Takemoto):
