The Robotic Arm
In order to maneuver objects, robots need effectors and end effectors. Effectors are like an arm for the robot. They can move and direct the end effector. The effector also connects the end effector to the robot itself, just as your arm does for your hand. Also depending on the size and the function of the end effector, effectors need to be durable and versatile enough to support it. For example the Canadarm on N.A.S.A.’s space station needs to be durable enough to with stand the conditions of space. On the other hand, the Haverhill Robotics team Large Robot just needs to be strong enough to support a couple of cotton blocks. The end effectors in return need to be just as durable and versatile as the effector that supports them. End effectors can move, turn, and/or twist objects in any sort of way. In order to move like this however, the end effectors require gears, motors, and servos. Without these, the end effectors are not able to grab, move, or so much as even lift anything. Although end effectors can do all of this, they should be designed for one task only, so that it does one task and it does that one task well. For our robots in Botball we used effectors and end effectors. On our big bot (Gladis) we had two effectors. They would clamp together onto the red blocks (radio towers) and then using the end effectors, they would flip the blocks over Gladis and place the blocks over in the times two area.

Our small bot (companion cube) had two effectors connected to a basket which was the end effector. The basket would push the blocks out of the way and collect the ping pong balls (biofuels) and then pour the biofuel into the 5 point bio fuel area. (A picture of Companion Cube...
