Parallel Joe is the robot built for the VEX category by the 12th grade students. In this challenge: Gateway, the robot must take cylinders and spheres made of plastic and put them in the targets through the entire field.
In order to reach an efficient design, the team was based on the chassis of a previous robot, which used two omnidirectional wheels and 2 traction wheels drive. Finally, after a few tests and competitions, they decided that the best powertrain for this challenge was using 4 omnidirectional wheels, each one connected to four major engine modules.
Its arm is based on a system of parallel bars, with 4 small engines with a torque reduction. Some rubber bands placed on the sides of the parallel bars help the motors who lift the arm giving an extra force upwards.
