#1 - Gambler bot

Mid term tasks

Challenge criteria

Ramp requirements

These are the requirements of the ramp to drop the dice.

The work was to pick up and drop the dice on the target:

Target dimensions:

• Rectangular platform

• Dimensions (h=45mm, w=92mm, l=92mm)

Dimensions of cubic dice:

• A: Rounded edge, (15 x 15 x 15) mm

• B: Rounded edge, (12 x 12 x 12) mm

Terrain:

• PVC flooring

• Slippering (but still workable for micro:Bit Robot Platform)

Bot requirements

Servo turn: 180 degrees

Options:

1. Rack and pinion system

2. Standard servo-based rotation (like this one: Robotics Training - Basic Rack & Pinion Lift - YouTube)

Other example options include: 5 Lifting Mechanisms - YouTube

Dropping slider ramp:

Drop triangle (right triangle): $h = 50 \text{mm, } b = 50\cos{60\degree}\text{, } p = 25 \text{mm}$, keeping the $\theta$ values by testing the ramp going through 30, 45, and 60 degrees (for standard servo-based rotation system).
