The model for the robot was designed in Solidworks. All images were rendered in Solidworks Visualize.
The robot used to counterspinning rollers to suck balls and blocks off the ground
The arm of the robot was driven by 3 planetary motors. This was because the arm was used to lift the whole 30 pound robot off the ground.
the three output shafts from the motor was reduced to one output shaft using a custom designed gearbox that would also gear the motors for torque
The robot used four industrial grade ultrasonic sensors provided by a sponsor, SICK. These were used to align the robot with the field boundaries during autonomous operation

2019 FTC Robot, Raven

For 2019 the team decided to go with a foam/plywood carbon fiber laminate construction. The goal was to suck up small balls and blocks, sort them, then deposit them into bins about 2 feet in the air. The robot would then have to lift itself off the ground attached to latches on the goal.
