How to Review a Robot's Centre of Gravity Before Movement Testing

List the battery, motors, controller, sensors, frame and payload intended for the test. A chassis can behave differently after a battery or raised component is added.

Use the actual planned assembly for the review. Do not assume that a bare frame or an image of another robot represents your configuration.

Identify every wheel or contact point that supports the robot on the test surface. Sketch the area between them and note parts that project beyond it.

This is a planning aid, not a stability certification. Component flex, wheel grip, acceleration and the surface can affect behaviour, so use appropriate supervision and controlled testing.

Record which heavy components sit high, far forward or to one side. Check that mounts are secure and that cables do not pull on moving parts or shift components.

Do not move a battery or other component without reviewing ventilation, protection, wiring length and manufacturer instructions. One improvement must not create another hazard.

With power isolated and under responsible supervision, place the robot on the intended level test surface and observe whether it rests consistently on its support points. Gently handle it only within the approved procedure.

Do not improvise tipping tests, stand beneath raised equipment or use hands to restrain a powered robot. Escalate uncertainty to a competent supervisor.

Use the defined test area, low-risk configuration and authorised control procedure. Begin with the smallest appropriate movement and watch for lifting, rocking or unexpected weight transfer.

Stop and isolate power if the behaviour differs from the plan. Record the observation rather than repeatedly increasing speed to see whether the problem disappears.

If a component position changes, update the build record and repeat the relevant checks. Keep photographs or diagrams tied to the exact version so another learner can understand the configuration.

RoboSkies supports structured learning and marketplace discovery. It does not certify stability, compatibility or hardware performance; responsible human supervision remains essential.

Does a balanced-looking robot prove stability? No. Can I test by catching a tipping robot? Do not rely on hands to restrain powered equipment. Must I review again after moving the battery? Yes.
