<p>I have built the accompanying robot earlier in the week. I have a challenge where the robot needs to find white/black bricks then store them on a tray and then travel over to another robot and transfer the bricks from the tray. I am an absolute novice with coding and I'm not sure where to start.</p>

<p>I have access to multiple EV3/NXT units. I'm thinking I might need 3? Any Help on programming, advice, hints and tips would be greatly appreciated. </p>

Daisy chaining is straightforward. In your EV3 project, you click the little wrench in the topleft to open the project properties and enable the option "Daisy-chain mode" below the project picture. The EV3 bricks themselves need to be connected with the USB to mini-usb cables that are normally used to connect them to your computer.

However, for the project you are describing, perhaps you could do with less motors and one brick would suffice:

* grabbing and lifting can be done with one motor as is is for example done in the gripp3r standard model included with the software.
* The double articulation of your claw arm might also not be necessary
* Perhaps the arm does not need to be able to rotate if the vehicle itself is maneuverable enough
