Product overview

The 4M Tin Can Robot kit shows children how to give a used drink can a second life as a walking robot. The can slides into body rings and is fitted with a motor, gears, legs, gripper hands and moving eyes.

Once switched on, the motor turns a worm gear and an axle with cams, which lift each side of the robot in turn so it wobbles forward with a buzzing sound. By adjusting the cam angles, children can change how it walks, and by swapping the wires and laying it on its side they can turn it into a sideways-walking robotic monster. The instructions also explain cams, reduction gears and how the can amplifies vibrations through resonance.

All parts are included apart from one AA battery, a small crosshead screwdriver and a clean, used tin can. Adult help is advised because metal parts may have sharp edges.

    Mega Hydraulic Arm

    The 4M KidzLabs Mega Hydraulic Arm is a build-it-yourself kit that uses water as the working fluid to move a multi-axis robotic arm. Children assemble the base, arm frames and claw, then fill syringe-and-tube sets with water to create four independent hydraulic circuits. Four handles on the base control the arm: one opens and closes the claw, two raise and lower different sections of the arm, and one rotates the arm from side to side. Pressing a plunger pushes water through the tube to move the matching joint, showing how force is transmitted through an incompressible fluid, the same principle used in cranes and construction machinery. The kit contains the plastic parts, eight syringes, tubing, claw pads and screws. A small crosshead screwdriver, some lotion as a lubricant and a clean used tin can are needed from home. Adult supervision is recommended during assembly.

    Motorised Robot Hand

    The 4M KidzRobotix Motorised Robot Hand introduces robotics and human anatomy through a hand model whose fingers tap out tunes and beats. Children assemble a motor and gearbox, the base, a rotating drum and four articulated fingers plus a thumb. The hand is programmed mechanically: pegs placed in the drum's slots lift the fingers as the drum turns, so each pattern of pegs becomes a rhythm. The kit includes program templates for planning patterns before transferring them to the drum. A gearbox slows the motor and includes a ratchet that protects the gears if the drum jams, while each finger works as a lever. Everything needed to build the hand is included except a small crosshead screwdriver and two AAA batteries. It is a good classroom link between programming, sequences and the mechanics of levers and gears.

    Tin Can Cable Car

    With the 4M Tin Can Cable Car, children turn an empty drink can into a working cable car. They build a wheel support with a motor and pulleys, attach the can as the car body with window stickers, and string a cable line between two points at least 2 metres apart, such as two chairs. The motor drives a power pulley that grips the string through friction, pulling the car along the line. When the car reaches a stop at the end of the cable, a reversing shaft flips the reversing switch and the car heads back the other way, so it runs to and fro automatically. The guide explains how pulleys act like gears to reduce speed and how reversing the current changes the motor's direction. The kit requires two AA batteries, a crosshead screwdriver and a used soda can, none of which are included.

    Table Top Robot

    The 4M Table Top Robot is a battery-powered robotic crab that children assemble themselves. Once built and switched on, it walks sideways across a table and turns when it reaches the edge so it keeps moving without falling off. Its edge detection is purely mechanical: when rollers pass over the edge of the table, a third wheel set at right angles touches the surface and steers the robot back until the rollers are on the table again. Cams on the axle move the plates that carry the eight legs and two claws, creating the crab-like scuttle. The guide links the design to real mobile robots that use sensors to avoid edges and obstacles. The kit includes a chassis with pre-installed motor, transparent cover, legs, claws, gears and an antenna. One AA battery and a small crosshead screwdriver are needed. It won a 2014 Parents' Choice Approved Award.
