This week we have been working on the projectile feature of the robot, as the original idea of firing nerf bullets is shooting them too fast and is unable to get them to drop into the top of the tank because the angle is wrong..
So, 2 members of the group spent their time designing the system of which projectiles could be flung off the robot into the Feed the Fish tank made last week. They started designing this concept based on the following loose design of a trebuchet- a medieval throwing machine.

Based on this Pavle began working on making a trebuchet like design to throw projectiles. He started designing this on CAD.
Another member worked on designing the projectiles that would be launched. He used Autodesk fusion to create two hemispheres as seen below, which can be glyed together after being 3D printed

Pavle also worked on laser cutting the sensor holder after designing it on CAD- here is the image of this being cut:

We 3D printed some of the projectile hemispheres as shown below:



Marin worked on printing the 2cm diameter circular projectiles from the Autodesk CAD design and then glued them together to make this :

Dhruv has been working on the code for the positioning of the robot for shooting the projectile balls designed earlier:

He also worked on the servo trigger for the shooting of the projectiles. Here is his code:
Akshat worked on fixing errors with the remote control but still has somethings to fix.
Robot club is on Easter holiday for 3 weeks now and will be back on 26th April
