This image gallery contains photos of Lego robots left in the course scrap box. Some of them are missing components, and none are attached to their HandyBoards. They are provided to inspire fresh Lego robot construction. At the bottom of the page, links are provided to other photo archives of ESG robots, for further instruction.

A sample gear box with a 1 to 243 gear ratio.
A six-legged walking robot.
A six-legged walking robot, from the side, showing the gears that move the legs.
A six-legged walking robot, from the top, showing internal gears and structure.
A 4-switch expansion board.
The switch board, from the side, showing the permanent glued bond.
A composite robot, consisting of three identical units linked together through universal joints.
The composite robot, from the top, showing the internal structure and connective bits.
A rolling robot, from the side, showing the gear-wheels.
In its partial state, the robot is prone to collapse.
With both sides uncollapsed, the robot is ready to attack!
A pneumatic claw setup, consisting of the Lego claw, a pump sensor, and a switch/connector unit.
A closeup of the pump sensor (yellow) and the switchbox, showing the single input and dual output hoses.
The two hoses lead into a pneumatic piston that opens the claw.
With the piston fully extended, the claw opens quite wide.
The Lego claw, closed.
A walking robot, with coupled gears driving the legs.
Full extension of one leg.
Full extension of the other leg, at the opposite point in the cycle.
The walking robot, from the side, showing the gear hookups.
A somersault robot, with gears and pulleys driving each branch.
A closeup of the middle, with all the gears and interconnects.
The multi-armed robot is essentially identical on the other side; note the underlying symmetry.
A mecha warrior, with a set of outer and inner legs.
The gearbox is open, and the outer legs are at the bottom of their cycle, holding the robot off the ground.
At the top of their cycle, the outer legs are slightly off the ground.
This triangular robot has three sets of wheels.
Sometimes it uses one set...
...but if it gets tipped over, it can move using the other set.
From the top, some of the internal gears.
This robot features a two-pronged claw at one end, and a smashing arm at the other.
The claw closes.
The smashing arm starts to descend...
Fully lowered, the arm can be used for many things, including lifting the robot.
Side view, showing control gears for the claw.
