OKK 635-Piece Robot Building Kit (11050): remote and app control explained

The OKK 11050 is a build-it-yourself robot kit with 635 snap-together pieces. Once built, the robot moves on tracks and can be driven with a hand-held remote or a phone app. It is meant for children who like construction toys and want to try a little programming, with a picture guide to lead them through the build.

Building the robot

The kit includes 635 pieces and a picture guide with step-by-step instructions. Parts snap together, and OKK says the robot uses servo motors and a gear movement system. A build of this size typically takes a good while, so it can work as a longer project to share with an adult. The listing describes the head, shoulders, arms, elbows, tracks and eyebrows as movable, so the robot can pull faces and gesture as well as drive.

Ways to control it

Two control methods are described:

• A 2.4GHz remote controller. OKK gives a range of 65 feet (about 20 metres) and says it moves the robot forward, backward, left, right and in a full 360-degree turn. The remote needs two AAA batteries, which are not included.
• A Bluetooth phone app with five modes, which OKK lists as app remote control, path mode, voice control, gravity sensor and STEM programming.

Path mode generally means you draw a route and the robot follows it, and a gravity-sensor mode lets you steer by tilting your phone. The programming mode is the educational part, where children can start to see how instructions turn into movement.

Battery and charging

The robot has built-in rechargeable batteries charged by USB. OKK says a full two-hour charge gives about an hour of play. Plan for charging time between sessions, and use a charger and cable suited to the connector, as the manual describes.

Age range

Listings for toys often state wide age ranges, and this one mentions children from 5 up to teenagers. Because the kit contains hundreds of small pieces, check the age grading and any small-parts warnings on the packaging. Younger children are likely to need an adult's help with the build and should be supervised around small parts. For many families the kit will best suit children at the upper end of primary school age, but that is a judgement for the adult buying it.

What it teaches

OKK describes the kit as a STEM (science, technology, engineering and maths) toy. In general terms, building from a guide practises following instructions, spatial thinking and fine motor skills, while the app programming mode introduces basic coding ideas. How much children get out of it depends on their age and interest.

Size

The box measures about 11.0 x 10.0 x 2.0 inches (roughly 28 x 25 x 5 cm). Once assembled the robot will be larger than the box, so give it room on a floor or table.

What to check before you buy

• Age and supervision: check the recommended age, and whether an adult will help with the build.
• Phone compatibility: confirm that the app works with your phone or tablet and the Bluetooth version it needs.
• Batteries: you will need two AAA batteries for the remote.
• Space: a smooth indoor floor or a firm outdoor surface is easier for tracked robots than thick carpet or grass.
• Small parts: keep spare pieces away from younger siblings and pets.
• Time: allow a few hours for the build, possibly across more than one session.

The short version

• A 635-piece snap-together STEM robot kit (model 11050) with a picture guide.
• Controlled by a 2.4GHz remote (about 65 ft range) or a Bluetooth app with five modes.
• Movable head, arms, eyebrows and tracks, as described by OKK.
• USB rechargeable: about two hours to charge for roughly an hour of play, according to OKK.
• Remote needs two AAA batteries, not included.
