The present project deals with the construction of a bicycle with a Bamboo structure, a cultivation plant preferably in the southwest of Mexico, however a bamboo cultivated in the Mexican Bajío was used. A transmission based on helical gears was also included, replacing the traditional transmission chain. Solidworks modeling was performed as well as finite element analysis to quantify bicycle safety factors as well as Von Mises efforts. Regarding the assembly and construction of the bamboo bicycle, different cuts of the plant's rods were made to adapt them to the tubular parts of the bicycle frame, in addition to the handlebar. The transmission was assembled with helical gears by coupling them with a power transmission shaft. Also tests were done, already armed the bike, both resistance and speed. And considering testing the transmission with gears.

Currently a large number of hand injuries occur in the Mexican population, mainly caused by accidents at work and in sports activities. To help the population have access to a brachiopalmar rehabilitation, In this work it was proposed to develop a rehabilitative prototype “dynamic hand orthosis” to address the main pathologies that affect our society (fractures, dislocations, sprains, tendonitis and sx of the carpal tunnel). The design was analyzed in a finite element for its validation, having a safety factor of 2.6 and a maximum tension of 12.84 MPa below the ABS elastic limit, Manufacturing was done using a 3D printer with the ABS filament. This orthosis has an extensor finger attachment composed of hammocks, one for each finger. Due to its universal design, it can be used for both hands only by exchanging the extension of the thumb.
