Skip to 0 minutes and 7 seconds Welcome to week one in the robotics project, My name is Liam O’Sullivan and I’ll be your guide as to how to design, construct and program this robot to move in a 2D workspace. I have a robot that I built here. Let’s take a look at this robot sitting on our robotics worksheet and the task that you have to do. This is the robotic’s worksheet and I have the robot that I built with Lego sitting on top of it. The key thing to know with the robotics worksheet is that there are 5 points, listed from 1, 2, 3, 4 and 5. These points are also listed down on the table below here.

Skip to 0 minutes and 40 seconds And they’re in x and y coordinates, which are in millimeters, and these coordinates is in reference to this Cartesian axis down the bottom corner. Now what your robot actually has to do, it has to move from point one to two, up to point three, four and then finally finish at five. Let’s take a look at this robot now moving through the robotic worksheet.

Skip to 1 minute and 31 seconds This is another robot that I’ve constructed. It is made out of Lego Mindstorms EV3 kit. It is a revolute prismatic robotic arm. Let’s take a look at it moving through the robotics worksheet.

Your task is to build a simple robot, with two joints, that can carry a pen or pencil and draw on a sheet of a paper. You will create software that enables the robot to draw straight lines between points. In the video, we’ll show you what your finished project might look like.

Here are the general steps you’ll take to complete this project:

1. Decide on what hardware and software you’ll use.
2. Decide on the number and type of joints you’ll build.
