【Science kit】Hydraulic Robto Arm

Usually the operation is not smooth because the burrs are not trimmed cleanly. Check whether the burrs of the parts are completely cut according to the instructions.

Parts are missing or the part board is broken or broken during disassembly and assembly

You can contact our online customer service for supplementary matters

Please confirm whether the burrs of the E10 gears are cut off cleanly. If there are burrs, the two gears will be stuck when running.

Why does it spin when assembling the direction changing rocker?

1. There is a foreign body stuck on the G8 or E16 gear, if there is, it will cause idling.

2. If the screws are not locked in position during assembly, it will cause left and right shaking and idling

Why does the hydraulic pipe leak when it is pressed?

Please check whether there is oiling when assembling the hydraulic pipe, or the piston cap of the plug is skewed, causing the hydraulic pipe to be airtight and leaking pressure.

The gripper rotates very tightly, although it can complete the action but cannot be retracted?

Please confirm whether the piston ring of the hydraulic pipe is oiled, and check whether the spring is installed incorrectly.

Why are there gaps in the gripper jaws and can't grip things?

Please confirm whether the assembly direction of D8 and D9 parts is wrong, if wrong, the clamping angle will be different and it will not be able to close.

Why can only do half of the action?

Please confirm whether there is too much air in the hydraulic pipe. If there is too much air in the pipe, the action of squeezing water will be inaccurate, resulting in insufficient strength.

Why is the joystick not sticking smoothly?

Please check whether the joystick direction is wrong, the wrong direction will make the control angle smaller.
