Chosen Design

After careful consideration, I chose the aggressive vertical front spinner as my final design. I have moderate to extensive experience in Onshape, so i used that to begin designing. Before beginning to design, i found STEP files for N20 motors and used the dimensions from my planning stage to place in the electronic components. Then i began with a roughly shaped sketch of the design, which i extruded to the desired length. Then I shelled it out with a 2mm wall to allow space for the electronics.

Weapon design

My weapon blade design is based off James KIrby’s D.E.S blade. The weapon support struts are extremely thick as many bots have lost their weapons due to broken struts. The weapon uses a BE1806 motor and a 20Ah ESC to drive it. The weapon unfortunately was not big enough to house the motor, so adjustments had to be made to allow a larger weapon.

Feedback and Re-iteration

An extremely helpful individual from the university provided me extensive feedback upon the design, which significantly improved my design and allowed my robot to remain under the weight category. Thank you!

Specific Design modifications through feedback;

• Changed Malenki nano orientation to vertical just behind weapon
• Allowed the wheels to protrude slighly from the back so the bot doesnt get stuck on its back
• Smaller chassis for lesser weight (Removed unecessary space)
• Added Mounts for screw switch and LED

If you made it this far, thank you for reading! If you have any suggestions for my bot, I’m always willing to improve, so please tell me in the comments below. Thanks!

Final Design is attached below along with a wiring diagram (It should be unless theres something else to fix)

P.s there’s a cover on the bot, i just dont have it visible in the renders
