First test of the bobbin actuator to meaure travel.
This is a video of a single actuated 1-joint robot built at the Manipulation and Biorobotics labs at the Robotics Institute - Carnegie Mellon University. By using dynamic motions, it is possible to build a 1-joint robot that climbs up a parallel chute. The test-bed is an air-table which keeps the mechanism planar.

THIS IS A DEMO OF FIRGELLI TECHNOLOGIES L12 MINI LINEAR ACTUATOR
Speed : 8mm/s
Stroke : 24mm
Weight : 32g
Lod trust : 30N
This was a school project where we had to design and build a "syringe robot" that had four joints and could stack wooden blocks into a pyramid. I think it's more of a mechanical arm because it really doesn't do anything automatically. It works pretty well, although the gripper is more complicated than it could be. Overall, I think mine was the second best in the class.
The following video shows how the joints work:

The Most Advanced Quadruped Robot on Earth
BigDog is the alpha male of the Boston Dynamics family of robots. It is a quadruped robot that walks, runs, and climbs on rough terrain and carries heavy loads. BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog's legs are articulated like an animal's, and have compliant elements that absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule, measuring 1 meter long, 0.7 meters tall and 75 kg weight.
The General Dynamics Land Systems EFV is an amphibious armored tracked vehicle with an aluminum hull. The EFV has a crew of 3pax and can transport 17 Marines and their equipment.
The aluminum hull has caused some controversy due to protection and flammability concerns. However, aluminum hulls have been used for decades in military ground vehicles and boats. The rear loading ramp is not able to open while the vehicle is afloat. This is also typical of other swimming military ground vehicles. For example, the M113 is another armored military ground vehicle the US currently is using that swims. It also has an aluminum hull, and its rear ramp cannot open while the vehicle is afloat.
The engine is a custom MTU Friedrichshafen diesel (MT883) with two modes of operation; a high power mode for planing over the sea, and a low power mode for land travel.
The hull has a hydraulically actuated bow flap to aid planing. Shrouded Honeywell waterjet propulsors are integrated into each side of the hull and hydraulically actuated chines cover the tracks while in seafaring mode.
The Expeditionary Fighting Vehicle (EFV) is the newest USMC amphibious vehicle, intended for deployment in 2015.
This vehicle is an amphibious armored personnel carrier; launched at sea, from an amphibious assault ship beyond the horizon, able to transport a full Marine rifle squad to shore. It will maneuver cross country with an agility and mobility equal to or greater than the M1 Abrams.
The EFV is designed to replace the aging AAV, and is the Marine Corps' number one priority ground weapon system acquisition.
The EFV has 3 times the speed in water and about twice the armor of the AAV, and superior firepower as well.

How to build a simple 2 DOF multipurpose motion simulator using recycled bits and pieces and 2 souped up linear actuators. ..With a bonus feature describing a mobility scooter hack 2 DOF motion sim using a reduction gear and crank setup.
Each group of 3-5 students needs to design an intelligent robot from scratch with various actuators, sensors and a microprocessor communicating with a Base Station (BS), which is a PC, through a wireless modem. The on-board sensors include a pair of motors, a servo, infrared and ultrasonic range finders. The robot is driven by a pair of motors mounted on the custom-made frame of the robot.
The robot and the BS are programmed for different missions, including autonomous waypoint following, mapping, tracking, obstacle avoidance and path planning. The on-board microprocessor can handle all low-level control and simple tasks, such as obstacle avoidance, without the support from the BS, while the BS with high computational power is responsible for more intelligent tasks, e.g. real-time path planning.
For localisation, each robot carries a reflective tape. A Laser Range Finder (LRF) scanning the reflective tape acts as a virtual GPS which provides the locations of all robots in the range of the LRF. Having the feedback from the LRF, autonomous waypoint following is achieved by implementing a controller.
~NOT MINE~ R32 skyline ...2.8 liter stroker 6 speed hks transmission low boost..
The HCR32 Skyline debuted in May 1989. It was available as either a 2-door coupe or 4-door sedan/saloon, all other bodystyles were dropped. It featured several versions of the RB-series straight-6 engines, which had improved heads (the twelve port inlet was gone) and used the ECCS (Electronically Concentrated Control System) injection system. Also available were an 1800 cc 4 cylinder GXi model. Most models had HICAS four wheel steering, with the rear wheels being hydraulically linked to the front steering. The 2.5 litre version became one of the first cars made in Japan to feature a 5 speed automatic transmission. The GTS-t Type M included larger five-stud 16 in wheels, four piston front callipers and twin piston rears. ABS was optional (except for the GT-R), viscous LSD was standard on all turbo models and optional on all but the GXi.
GXi Type-X - 1.8 L CA18i I4, 91 hp (67 kW)
GTE Type-X - 2.0 L RB20E I6, 125 hp (93 kW, 172 N m)
GTS Type-X, S, J - 2.0 L RB20DE I6 155 hp (115 kW, 184 N m)
GTS-25 Type-X, S, XG - 2.5 L RB25DE I6, 180 hp (132 kW, 231 N m)
GTS-t Type-M - 2.0 L RB20DET turbo I6, 212 hp (158 kW, 263 N m)
GTS-4 - 2.0 L RB20DET turbo I6, 212 hp (158 kW, 263 N m) Atessa (RWD w/ FW assist)
GTS-4 - 2.6 L RB26DE I6, 225 hp (169 kW, Atessa (RWD w/ FW assist) Autech Version - auto only
GT-R - 2.6 L RB26DETT twin-turbo I6, 280 hp (206 kW, 368 N m) Atessa (RWD w/ FW assist) also NISMO, V-Spec and V-Spec II variants.
The GT-R returned with twin ceramic turbochargers, all-wheel steering, all wheel drive, and 280 hp (206 kW) at 6800 rpm. The RB26DETT engine actually produced ~320 hp, but it was unstated due to the Japanese car makers' "gentlemen's agreement" not to exceed 206 kW (276 hp). The engine was designed for ~500 hp in racing trim, and then muzzled by the exhaust, boost restriction, and ECU. The electronic boost control had a small physical restriction in the control lines. It was marked in yellow so the new owner could remove it and enjoy a safe factory boost increase. The GT-R had Super HICAS, a more advanced computer controlled four wheel steering system using electric actuators.
The GT-R had a significantly larger intercooler, larger brakes, and aluminum front guards and bonnet. Other distinguishing features include flared front and rear wheel arches. More supportive seats were fitted, and the turbo boost gauge and digital clock were removed from inside the instrument cluster. The clock was replaced with a torque meter that indicated how much torque was being delivered to the front wheels (0%-50%). Oil temp, voltage and turbo boost gauges were fitted below the climate control.
The Porsche 959 was Nissan's target when designing the GT-R. The chief engineer, Naganori Itoh, intended to use the car for Group A racing, so the design specification was drawn up in conjunction with a copy of the Group A rules. The Nordschleife production car record at the time of development was 8'45" - set by a Porsche 944. Nissan test driver Hiroyoshi Katoh reset the record with a time of 8'20". Best Motoring managed 8'22"38.
The R32 GT-R dominated JTCC, winning 29 races from 29 starts, taking the series title every year from 1989-1993. It took 50 races from 50 starts from 1991-1997 (latterly R33) in the N1 Super Taikyu. The R32 GT-R was introduced in the Australian Bathurst 1000 touring-car race to compete against GM Holden and Ford V8 saloons, winning in 1991 & 1992. This success led to the Australian motoring press naming the car Godzilla due to it being a "monster from Japan" and as Australia was the first export market for the car the name quickly spread. However, the GT-R's success was a major contributing factor, sounding the death knell of Group A Touring Car racing; with the formula being scrapped soon after. JTCC was similarly blighted by the R32 GT-R, and splintered soon after, leading to the switch to the Supertouring category and also indirectly to the GT500 category of today.
When originally designed, the homologation rulebook mandated 16" wheels, so that's what the GT-R got. This limited the size of the brakes, and the Nissan four pots weren't really up to competition use. A later change in rules allowed 17" wheels, so in February 1993 the GT-R V-spec (for Victory) emerged wearing 17" BBS mesh wheels covering larger Brembo brakes. The clutch actuation changed from a push to a pull system, and the car received an active rear differential. A year later the V-Spec II appeared with a new sticker and wider tires

With many operators and civilians alike. the Spyderco Military is the quintessential tactical folder. Its 4 S30V clip blade is extremely fast into action, locks up tight and stands ready for both thrust and slash cuts. The Millie wears a slightly larger 14mm deployment hole to facilitate gloved hand actuation. And along that theme, the nicely textured G10 grip is nice and big and provides plenty of real estate for various grasping options. As such the Military merits serious consideration ...
