My Current Robot

My Current Robot is what I call a dumper robot. It basically has a long arm that is connected to a big shovel that picks up and stores the balls. The arm is on the top something I call the tower which is connected to my drive base. My base has one omni and one grip wheel on each side. An omni wheel is a multi directional wheel so it is easier to turn with it. A grip wheel is a wheel with rubber similar to the wheels on cars. The base has for motors on it (we have a max of 6) to power the driving. I also geared the base so the base has more speed but loses torque (power). The arm is powered by the other two motors and it is geared for torque so it can lift all its load. The field is covered with balls that my robot can either put in the low or high goals. The low goal is on the ground and is just over a small fence every ball there gets you one point. The high goal is a big bucket and ever ball in there is worth three points. My robot gets the balls its collected in the high goal by raising its arm and the balls fall out of the shovel and onto a ramp then into the goal. There is also a ramp on the field and a robot on the ramp gets you ten points. Since my robot is able to climb the ramp and score a lot of balls in the high goal I have qualified for worlds and nationals in April.
