Biped1 uses only the parts that come with the Mindstorms RIS 2.0. One motor moves both legs fore-aft and the other rotates the ankles laterally. There is a touch switch on each foot that detects when the robot is leaning far enough to swing the other leg forward.

Mechadon is one of my on-going hobby robotics projects that I've been working on over the last 6 years. It has 12 degrees of freedom (6 per leg) and uses R/C servo motors for actuators. The "brain" is a parallel processing system using thirteen PIC16F84's (a relatively small 8-bit Microchip micro). It senses the world using a 2-axis analog tilt sensor in the head and 8 analog force sensors on the toes. The whole robot stands 18" tall and each foot is 4". It weighs about 6lbs. All computation is carried out on-board and the power supply is designed to be operated from a battery for totally autonomous operation. Like a human gait, the robot shifts its weight between feet and picks up its foot at the appropriate point in the step. All of the motions are based on sensor input (i.e. - no elaborate pre-programmed sequences of motion). Because of this, each step is slightly different than the last due to sensor error, mechanical slop in the linkages, etc...

This is my autonomous hexapod robot that I built a few years ago. It uses 12 R/C servos for actuators. The 6 that raise and lower the legs are Hobbico CS-72 1/4 scale and the 6 that move the legs forward and backward are several brands of standard 1/10 scale servos (all are similar the Futaba S3003). The total robot weight is a little over 5lbs and the payload capacity is around 5lbs additional. The vertical travel of the legs is 1 7/8". Overall length and width is 13" X 11". When crouching, it's 5.5" tall. When standing up there is 3.5" of ground clearance under the body. The robot uses a tripod gate for walking. The control system modifies the basic tripod gate based on sensor input so that it can climb over obstacles in it's way.

Biped2 uses parts from the LEGO Mindstorms RIS 2.0 and the #8455 Back-hoe Loader kit. The air tank on the top is a 500mL water bottle with an air fitting installed in the lid. Other than this and a couple hoses, all the parts are LEGO. Biped2 uses all pneumatics for walking - 6 cylinders in all. The walking motion is controlled entirely by air logic. When a cylinder moves part of the robot, it also moves a valve. This redirects air pressure to another cylinder, which moves another part of the robot and another valve, etc... The result is the cyclic walking motion shown in the video below. The programmable brick was not used on this design. There is also no motor, batteries or pump on-board the robot.

The programmable brick was not used on this design. There is also no motor, batteries or pump on-board the robot. Biped2 uses parts from the LEGO Mindstorms RIS 2.0 and the #8455 Back-hoe Loader kit. The air tank on the top is a 500mL water bottle with an air fitting installed in the lid. Other than this and a couple hoses, all the parts are LEGO. Biped2 uses all pneumatics for walking - 6 cylinders in all. The walking motion is controlled entirely by air logic. When a cylinder moves part of the robot, it also moves a valve. This redirects air pressure to another cylinder, which moves another part of the robot and another valve, etc... The result is the cyclic walking motion shown in the video below.

MiniMechadon was designed/constructed from Nov '02 to Dec '03. Currently, the mechanics and electrical hardware are complete. I have written some test code to exercise the servos and demonstrate the flexibility of the robot and for basic walking. The main goal of the project is to experiment with learning algorithms that will allow the robot to learn how to walk, rather than programming it to do so. The physical design is intended to be a simpler version of my Mechadon robot (12 DOF). While simpler than Mechadon, I feel there is still enough complexity to make the problem interesting while not being overly elaborate. My hope is that the techniques developed with MiniMechadon can be extended to more complex robots such as Mechadon.
