Evolution of mechanical projects

Arena:

Arena

The colored grid was done with painted sheets of A4, glued to the arena in a simmetrical manner akin to a matrix of diffent colors for the execution of task M3

The arena's communication with the webapp and user interfaces will be done through a computer, already set up on the arena

The charging point was hooked through a hole in the north wall of the arena, and connected to power directly to a common mobile charger.

The robot's claw was hooked to a SG40 servo and made to actuate to test its reliability. It seems to be stable but the servo placement was not good enough

The moveable boxes to be place in the arena were done through various iterations, The current one allows the pincer to grab it from all sides,

Mechanical diagrams and preview

Robinho's mechanical systems are surprisingly complex, forcing the team to manufacture multiple parts from scratch. Thus we decided on designing all the parts in CAD for 3D printing in PLA, which is lightweight, cheap and resistant enough for all the applications. The mechanical parts are separated first into: The robot chassis The robot's claw The arena The robot's chassis The base of the chassis was bought from the internet, we chose a reliable and readily-available model which is commonly called "2WD Circular robot chassis". It has a standard diameter of about 14cm (excluding the wheels), fitting our specifications for the project. Above the prebuilt base we assemble two other plates made of acrylic plastic, separated by 6cm inbetween. The distance was measured as the minimum distance to allow fitting of the entire payload of the first baseplate, which was composed of: The claw mechanism The batteries The wireless charging module The color sensor The...
