You can control it directly via R/C, but the connector is not ideal - you can either push the wires directly into the port (not great), or use a breakout board with the matching connector. Refer to the user guide pages 53+. You can likely find the mating connector on Digikey.
We currently do not have a battery which is powerful enough to run the CIM motor. You would need a 12V, 10Ah or more. If you want to operate it for a decent time, you’d need at least 30Ah, and have a spare ready to go.
You would need to make it or contract out. You can consider starting with a dense wood.
This confirms that the paintball mini gun used in the show “Community” at the end of season 2 was real.
Yes, that would work. Notice that the weight is ~32 lbs. If each motor consumes around 10A continuously (for a total of 40A), and the robot has a total efficiency of ~45%, then that battery should last for about 20-30 minutes.
When you design the base, make sure to do so such that the robot can turn properly with as little resistance as possible. You may even want to consider only two motors (with a higher gear ratio) and using swivel casters in front and in back.
You’ll need RB-And-09 (0.5" bore, mates with Plaction wheel), as well as a key and two 0.5" bore shaft collars per shaft (McMaster is a good source). The wheel would need to be mounted very close to the motor, and ideally have the shaft supported at the end as well.
For two motors, using the Drive Motor Sizing Tool, you would need about 3000 oz-in of torque. The CIM motor provides 345oz-in, so you would need at least a 10:1 gear ratio, perhaps a bit higher to be safe. If you use four motors, they would each need a 5:1 gear ratio. Consider 2x RB-Ban-79 which is a 12:1 gear ratio. You would need a pair of casters at the front and at the rear to help support the load.
You don’t actually even need the Arduino MEGA if you plan to control the robot via R/C. You can certainly do gradual acceleration without the motors. Here is an idea of the setup:
Note that the Arduino cannot provide enough current to power normal lights - each pin can provide 40mA, which is enough for a small LED. If you want to run larger fans or lights, you’ll need to use relays. Cooling fans should be directly connected to the power supply, and you can connect all lights to one R/C relay (again, no need for a microcontroller).
If you really want to use an Arduino MEGA, you can certainly use an XBee, though communication would likely be from a computer. We offer the 785HB servo which can rotate continuously - but not all remote controls can send the right signal. Note that you can control the speed of a DC gear motor via R/C signal using an R/C DC motor controller.
Pretty much - the command protocol is all detailed on page 93 and up in the user guide. You should not power the flashlight from the Arduino - use a relay.
The battery does not seem to be included with the kit (AM-2229), but we are checking with the manufacturer just to be certain and will get back to you here… The vast majority of the connections use screw terminals, and no “delicate” soldering" is required.
We do not carry chargers for such big Lead acid batteries, although it would be appropriate for your design. You can find such charger as automotive accessories in a local hardware store.
