Enclosed Heavy Duty 4WD All Terrain Robot Kit

This is our recently revised Deluxe ATR kit. It has been revised to remove the back slope so more batteries and controls can be installed. It is an extremely rugged well built robot. It was originally designed as a water tight robot to go into mines. The robot is entirely enclosed and can be used in all weather conditions. The wheels are axle mounted and supported using two sealed ball bearings. Each of the four axles are driven by a large and powerful IG42 Gear motor via a roller chain to yield a very smooth and slip free mode of operation. This robot is designed for loads greater than 20lbs. For loads greater than 35lbs you need to go with lower gear ratio motors and foam filled tires. The biggest issue is pivot turns on carpet and grass takes a great deal of torque to skid steer, especially with the high traction tires we use.

The ends of the shafts are exposed on the inside if you wish to mount encoders to them. Or you can select gear motors with encoders on them. There are side access panels that allow easy assembly of the motor and chains and adjustment of the chain tension.

For more information on the chassis itself, please see the chassis' main page here.

The kit provides you with what you need to make a great enclosed All-Terrain robot. Below are many options to make a basic robot platform to be powered with a microcontroller. We include a bunch of hardware and electrical wires, fuses, switches, connectors, motor hookup kits, etc to get you going. We also offer assembly of this robot kit. When you purchase this kit you will get access to our assembly manual that contains color images and step by step instructions. There are a lot of options and additions you can select, the links of all the items are included below. Follow the links for details of each item and option.

For further details and descriptions of the ATR, see our ATR Robot Building Page. Additionally, you can see our Videos Page to see this robot in action.

Standard Items:
	The following items are standard with this package: Heavy Duty 4WD Enclosed Chassis with Acrylic Covers (Qty 1) 6.75 inch Tire Wheel Set - TAM-007-000 (Qty 2 sets) Electric Motor Hookup Kit - TE-024-000 (Qty 4) 15 Amp Connector Set - TE-027-015 (Qty 3) HD Electric Power Hookup Kit (Qty 1)


Motor Selection:
	For the motors, the standard motor is our 252 RPM motor, but you can also opt for the 122 RPM motor if you want a more power and a less speed. We also offer the 75 RPM motor for a whole lot of power and a even slower speed. If you want to use encoders, we offer a 252 RPM motor with encoders that will fit in the robot.


Battery Options:
	For the motor batteries, you can choose for one of our 24V batteries. Battery life depends greatly on how you use the robot, what terrain you use it in, how often and sharp you turn (since its skid steering which draws considerable power), etc. A single battery can last from 1/2 hour to 4 hours depending on usage. 24V 4500 mAHr NiMH Battery Pack - TE-099-220 (Qty 1 or 2) High Power 22.2V 3Ahr Li-Ion Module - TE-124-222 (qty 1) High Power 22.2V 10Ahr Li-Ion Module - TE-119-222 (qty 1)


Motor controller Options:
	If you just want to drive the robot via a microcontroller or other device, you will need motor controllers. Motor controller options are listed at he bottom of this list. For more support see our Motor Controller Support Page. If you wish to make your ATR RC control see our Enclosed Heavy Duty 4WD RC All Terrain Robot Kit. MD22 Devantech Dual Motor Driver - TE-020-000 (Qty 1) MD03 Devantech 20A 50V Motor Driver - TE-036-000 (Qty 2) PWM Motor Controller 3A 12-55V - TE-058-000 (Qty 4) Sabertooth Dual 10A Motor Driver - TE-091-210 (Qty 1) Sabertooth Dual 25A Motor Driver - TE-091-225 (Qty 1)


Front Embedded Halogen Light Option:
	This option provides you with two embedded halogen lights with a borosilicate glass cover (thermal shock resistant). This option has to be ordered at the time the robot kit is ordered since it involved a different front panel that is welded into the chassis. The option also includes a 12V 4000 mAHr battery for running the lights.


Camera Dome Option:
	This option includes a 8" camera dome. The top cover is laser cut with an opening and mounting holes for the camera dome. The camera dome is 4" high. There is a large tray below the opening for mounting a camera pan and tilt system.


Foam Filled Tire Option:
	This option should be selected if you wish us to fill your ATR tires with foam. The procedure can also be done by yourself and is outlined in the ATR manual. The standard tires are pneumatic and can handle the weight of the deluxe ATR with no problem, but if you want to add a bunch more batteries, or other equipment, or if you don't want the tires to give during impact you can fill the tires with foam.


Assembly:
	You receive access to our fully illustrated manual that helps you assemble the robot. If you wish you can have us assemble the robot select mechanical, electrical or complete assembly. If complete assembly is selected the robot will be completely assembled and tested and will be ready to go out of the box. Assembly adds 1-2 weeks the delivery.

This item is built to order and usually ships within 3-7 business days depending on volume and assembly options.
