In this week, many new parts were fitted to hold items in place such as the fan, the raspberry pi camera, the 16 by 2 I2C display and the battery.
CAD models of these holders were used to generate STL files that were then used to print them on the 3D printer
Here is the CAD model for the servo controlled grabber arms that fit on the front of the robot : A slight modification was needed to remove a part of them so that they would open fully without hitting part of the main chassis
This image below is after all the holders were printed and then all parts which need holders were added to the robot. You can see the 16×2 LCD display on the top and the block grabber arms at the front with the camera mount just behind them.
One member spent his time designing the obstacle course the robot will travel in.
The programmers managed to get the grabbers working – but we had to replace one faulty servo. The controller and motors were combined in software so now we can drive the robot forward & back with the wireless gamepad style controller.
Two other boys have been working on the Nerf bullet firing mechanism this week.
We now break for Christmas this week, so will be back with more updates in January
