Operate a gantry-mounted robot claw. Lead moving blocks on the conveyor, lower the jaws to grip one, then carry and release it into its matching bin. Acceleration, gravity, and settling make every delivery count.
Catch a moving block
Move over the belt with W and line up slightly ahead of a moving block. Press Grab or Space. Wait while the claw lowers, closes its jaws, and lifts. The block must be between the jaws when they close.
Find its matching bin
Use S to travel toward the bins and A or D to line up. The carriage accelerates and brakes gradually. Match the color and shape: red circle, blue square, or yellow triangle.
Drop and sort again
Release the movement controls and wait for the carriage to stop over the matching bin. Press Drop or Space. The block falls and bounces; Sorted increases only after it settles inside the correct bin. Missed blocks return to the conveyor.
A compact robot claw
A supported gantry moves a two-jaw gripper along rails. The claw lowers to grip a block, closes its jaws, and lifts to a safe carrying height.
Color and shape matching
Each block and bin has a matching color and symbol. Red uses a circle, blue a square, and yellow a triangle.
Motion and gravity
The carriage accelerates and brakes. Released blocks keep their sideways momentum, fall under gravity, and bounce before settling. A miss returns to the belt.
Time your sorting
The timer starts when you move or grab. Best tracks your fastest successful sort during this visit.
Hold the movement buttons or use W, A, S, and D. Arrow keys work too. W moves toward the belt and S moves toward the bins.
Lead a moving block slightly and press Grab or Space. The automatic cycle lowers and closes the jaws. The block must still be between the jaws at the bottom of the cycle.
Drop always releases the block. Only a block that settles inside its matching bin earns a point. Missed blocks return to the conveyor so you can try again.
