After researching existing • Concept solution 1 designs we found that ramps played a big aspect in the design so we tried to incorporate this into our design. • Sticky wheels was another aspect that seemed to be key for winning robots. Low to the ground we felt • was a key point that we felt should be included in the design to prevent other robots from lifting us out of the ring. What let this design down • was that it is hard to include a second function into the design.

Concept solution 2 This solution was • based on the premise that our bot would be hard to push if with the sloped edges and no flat sides. The con to this design • is that it will make it difficult to be able to push other robots out of the ring. Our second function • for this robot is that a strobe light would be added to effect the sensors

Concept design 3 • This design was a progression from the previous design including both the ramp truncated edges from concept design two. The secondary function of • the robot will be fold down sides which will allow us to start off in the max dimensions and extend past that when the battle begins. This design also incorporates • the sticky wheels used in the other designs to maximise the torque of stepper motors.

Rationale for our design This design will prevent other robots from getting underneath ours and reducing our  traction. The three ultrasonic sensors will allow us greater control over the robot and allow us  to sense possible attacks from the other robots. This design will allow us to put most of the weight into the base which will allow our  robot to have a lower centre of gravity. Using silicon based tyres will hopefully give our robot superior grip over robots using  rubber tyres. Using a big battery pack will allow us to increase weight in the base and give ample  power to the motors and the pic board Using four LDR’s on each corner of the base will allow our robot to sense the ring in  all directions to prevent accidentally coming out of the ring

Specific Material requirements  Servo Motors (these we have and plan to hot wire to rotate 360°)  Rims to be made out of aluminium 50 mm solid round bar.  Tyres to be made from silicon based material that will be created by ourselves.  Base to be made out of 2mm brass or stainless steel scrap chute material. 200×200  Top plates to be made out of aluminium sheet 400X400
