Bricks Are solid and tall blocks. The name corresponds to the amount of connectors and its shape. They are used to build the body of the robots.

1x2 Roof 1x2 Inverted Roof

2x8 2x6 2x2 Corner

2x3 Arch 2x4 2x3 Inverted Roof 2x2 Roof Weighted

Beams Beams are used as supports and some times to reinforce structures. They come in a variety of lengths and have holes in them to insert axles and connectors. They have only one column of connectors and the name depends on the amount of connectors on the column and its angle.

1x8 1x6 1x4

1x2 Double Angled Angled

Plates These are flat pieces that also come in a variety of lengths and widths. They are commonly used to join other pieces and as a base. The name is given by the amount of connectors, shape, and use.

Axles Axles are used for gears, pulleys and tires. There is a variety of axle lengths and the name depends on its length in studs. (from 2 to 12 studs)

12 Stud 10 Stud 8 stud 3 Stud

6 Stud 5 Stud 4 Stud 2 Stud

Bushings They usually go on axles to hold them in place. Half or short bushings, which are also small pulleys, have more friction than the full bushings and provide a tighter grip.

Bushing Short Bushing

Connector Pegs Are inserted into the holes of the beams to connect and reinforce pieces. The gray connectors allow the pieces to rotate freely. The black connectors fix the pieces in a position and do not let them rotate. There are also connectors with axle to attach tires to beams.
