Category: Automation Circuits / Robotics Views: 4452 Rank: 0 The SIMD1 V3 is very similar to the NPN flavor of SIMD1 V2, but with the addition of a FET on the output line. This makes life easier for its attached load (since there`s no need here for something that can use an `enable line`), by providing power that`s just `there` in the dark. Here the FET is used to sink load current from a pummer, motor, or whatever. visit page.
Related circuits Code provides adjustable differential drive for robots Intelligently modifying the motor-drive commands to a robot can give you control finesse during competitions. Moving a joystick hard right, for example, might have different effects, depending on the robot`s speed and direction. Software running on an inexpensive microcontroller (in this case, an... The P5v2 5-motor walker circuit The 74AC240 chips (U1-U5) are used as H-bridge style motor drivers since they have almost double the drive current compared to 74HC240 chips. These motor driver chips are permanently enabled by grounding control pins 1 and 19. The two groups each have four inputs connected in common to a bicore... RF is just way too cool not to use in your designs. But if you`re a newbie like me it is difficult to successfully build solid RF transmitters and receivers. When I started out I didn`t realize that the larger breadboard I was working off of was causing a lot of the signal deviance because the... Dual dc-motor-speed controllers navigate robots Mobile robots need simple and lightweight dc-motor-speed-control hardware that can work with low-power batteries. Flip-flop type navigation systems allow only one motor to operate at a time while the other motor remains off. Navigation direction changes alternatively even when the robot has to... As you can see, we introduced a PIC into the circuit. Actually this is our first contact with the 16F84 from Microchip . To handle with such a micro-controller, one has to own a programmer, a hardware interface to the PC, where the chip is programmed. We found a design of such a programmer in the... Craig Maynard dreamed up the Chloroplast solar engine (an interesting design, tho' it uses two parts you probably won't have sitting around in your parts drawer). Since I really can't describe it better than Craig can, here's his description (from the Chloroplast web site), followed up by... The "Happy Birthday Singer" solar engine The happy-birthday singer is a two bit wide by n words deep programable sequencer with 4 commands: reset to start vector (00), decrease frequency (01),increase frequency (10), and pause (11). The device starts out with a 2 word vector jump at the start of memory which locates 16 positions in it`s... Me and a friend are both trying to build a millipede. Because of obvious reasons, the millipede is NOT going to have 1000 feet!!! Instead, it`s going to have 16 pager motors as feet. It will also have 3 MicroMotors to ``bend`` towards light, and a backup sensor. Comments
