Building the cargo
Now that the arm mechanism has been built, you need an element to pick up. You will now build a cargo build to practice using your claw:
- Start with two black 2x8 plates and place them side by side, as illustrated in Figure 2.48:
Figure 2.48 – Two black 2x8 bricks
- Connect these elements together using two purple 2x5 blocks and place them at each end, as shown in Figure 2.49:
Figure 2.49 – Join together using 2x4 blocks
- Insert a yellow 3L axle into the middle of each purple 2x4 block, as shown in Figure 2.50:
Figure 2.50 – Insert a yellow 3L axle
- Slide a gray bushing onto each yellow axle, as shown in Figure 2.51:
Figure 2.51 – Insert a gray bushing into each axle
- The next step is to add a yellow 90-degree connector to the top of each yellow axle, as shown in Figure 2.52:
Figure 2.52 – Add a yellow 90-degree connector
- The final step is to use a 5L axle and, in the middle, slide it onto a tire. Secure the tire using a gray bushing on each side. Finally, work the 5L axle into the two yellow 90-degree connectors, as shown in Figure 2.53:

This will be the cargo item we will use to grab and move to different locations. Next, it will be time to move on to the coding to bring the robot claw into use.
