REV FIRST Global Building Manual

6 The female hex shaft of the Core Hex Motor allows for any length 5mm hex shaft to be inserted through the body of the motor (Figure 8). The motor can drive wheels or gears on either side of the shaft, or a single shaft can be put through multiple motors to increase the power. If multiple motors are used on a single shaft, be sure that they are being controlled in the same direction to prevent damage.

5 2.3 DC MOTORS DC motors are used to power wheels and control moving robot parts, like arms. The Core Hex DC Motor (Figure 5) included in the FIRST Global Kit has a 5mm hex socket drive shaft surrounded by six m3 mounting holes on both sides called the Motion Interface Pattern. The back of the motor has a 2-pin connector for power and a 4-pin connector for an encoder cable. The normal rotation, the direction of spin when the motor is going “forward,” is marked with an arrow on the front of the m ...

34 Installing the clip as shown in Steps 4 and Step 5 of Figure 58 can be sometimes difficult. There are a number of approaches that may work for these steps, but a common method is to use a pair of needle nose pliers to grip between the back of the clip and the nearest pin to slide the clip (Figure 59). Figure 59: Installing the Master Link Clip with Pliers Master links are used to connect two ends of a section of chain to create a loop of chain. In order to use a master link, the chain ends should ...

18 Figure 31 - Figure 34 shows several possible combinations for bearings, motion brackets, and pillow blocks. In these figures the brackets are all depicted as facing “up” but brackets can also point “down” just as well.

2 2 ELECTRICAL COMPONENTS 2.1 ELECTRONICS 2.1.1 Introduction Robots are made up of mechanical structures and the electrical components that move and control them. Electronics is a broad category which includes motors, sensors, and programmable controllers or hubs. The REV Robotics Building System has two kinds of Hubs: Control Hub and the Expansion Hub (Figure 1). The Control Hub has an integrated computer module running Android and is where the robot code runs, while the Expansion Hub only provides ...
