SumoBot Presentation BY: CARL DALY, MICHAEL O’KEEFFE & JAMIE TUTTY

Factors to be considered Sumo Bot Attac Defence Structure Drive Materials Power Attack Maximum weight Low to ground Clamp Claw Flippers Spike More power towards flipper Tracks instead of wheels for more traction Control speed of bot Play around with idea of getting bot to move if flipped over Aluminium not steel Sand cast flipper Plastic may be to light Clean body work (prevent east disablement) Light- Flashing lights to distract Sound-buzzing sounds to distract Supports to prevent Bot from being flipped

Original Ideas and Sketches

What was learned from Modelling  1. The original height of the robot could be designed to be 20mm lower, which we previously listed was to be a design feature.  2. There are approx. 6-7 main areas where weight can be saved due to unnecessary walls or floor components.  3. Flipper mechanisms have been identified. Example: no use of gears, just direct link to the flipper drive shaft from the servo.  4. It is very possible to keep our robot close to the floor, making it harder to flip or to get under.

New Revised Idea What has improved: The front flipper has a completely new mechanism. Designed to tip, not to lift. Guard rails along the side

PARTMATERIALJOINING PROCESS SUMO-BODY2mm AluminiumBody walls to be joined using rivets. All rivets to be 3mm due to weight restrictions. Some TIG welding may be required. SUMO-BODY-LID3mm AcrylicTo be cut on laser cutter and fold corners folded on strip heater after. Will be fastened to body at two points only allowing easy access to on-board components. This will be achieved with small M4 screws. FLIPPER ARMCast Aluminium/ PewterThis will be manufactured using sand casting and hollowed out on the milling machine. This will be joined to the servo motor via a small bearing/bushing. WHEELSNylon/ RubberThese will be manufactured on the lathe and joined to the motors with small bushings or threaded bar(weight dependant to be made on CNC lathe). WOOD HEIGHT BLOCKSBalsa WoodThese blocks are to raise the motor to is required height and also act as a pivot point for one side of the flipper arm. To be attached to base with impact glue. Strength not crucial. BUMPERSAngle Iron (aluminium)To be attached to body with screws (M4)
