This guide explains how to build a motor chassis, which can for instance be used for the Lego Mindstorms model “Spike” powered by an EVshield with Arduino Uno.
- Lego pieces to connect the parts as displayed:
To make a sturdy, compact solution which allows access to batteries, ports and pins of both the shield and the Uno, follow the steps below.
This assembly can be the base to futher build a Lego model upon.
Add front of the assembly:
If you are building the Spike, add two beams (length 5.5 for NXT, for EV3 use a regular beam of 8). These will be used later to connect the legs to. Also at both motors add a pin:
Note: when you connect the legs, you have to remove the end-cap and place it back after the leg is connected (see Spike building guide pages 28 and 29).
Next, you can add the legs of the Spike to this chassis. Building the legs is detailed on page 22-35 of the Spike building guide.
