※本產品原廠代理從國外進口,有些交期較長,下訂前請詢問!

This rugged, 4-wheel-drive chassis from Dagu Electronics has independent suspension for each of its spiked 120mm-diameter wheels, allowing exceptional traction over uneven terrain, and its body is made from 2mm-thick anodized aluminum with a 10mm-pitch grid of 4mm holes, making it easy to mount electronics and accessories to the chassis. Assembly of the chassis is a simple three-step process that takes just minutes. This model is silver with chrome-colored hubs and has 34:1 steel gearboxes on the motors.

Overview

This rugged, 4-wheel-drive chassis from Dagu Electronics is a smaller version of the Wild Thumper 6WD chassis. It is designed to excel at traversing rough terrain, making it a great platform for any robot that needs to perform tasks in a complex outdoor environment. It features four powerful DC motors with brass brushes and 34:1 or 75:1 steel gearboxes that drive large (120mm diameter) spiked tires, and a unique “super-twist” suspension system acts to keep each wheel in contact with the ground for maximum traction, even when driving over uneven or bumpy surfaces. The suspension can be adjusted to suit different loads and conditions. The chassis is made from a 2mm-thick corrosion-resistant anodized aluminum plate, all of the nuts, bolts, and screws are stainless steel, and the brass fittings and suspension springs are nickel-plated.

When powered at 7.2 V, the version of the chassis with 34:1 gearboxes can reach a top speed of approximately 7 km/h (4.5 mph), and each motor has a stall torque of roughly 5 kg-cm (70 oz-in). At the same voltage, the version of the chassis with 75:1 gearboxes can reach a top speed of approximately 3 km/h (2 mph), and each motor has a stall torque of roughly 11 kg-cm (150 oz-in).

Using the Chassis

The chassis’ aluminum plate has 4mm holes spaced every 10mm, providing plenty of options when it comes to mounting your control electronics, sensors, and additional hardware. A compartment in the chassis has been designed to hold 7.2V sub-C battery packs (not included) that are commonly used in RC cars. Two such battery packs can fit in the compartment. The interior of the chassis also features convenient screw terminals for connecting your battery and motor driver leads. The motor leads are pre-connected to these screw terminals.

This is a differential-drive chassis, meaning that turning is accomplished by driving the motors on the two sides of the platform at different speeds. The two motors on each side of the robot are wired in parallel, so only two channels of motor control are required to get this chassis moving. The motors are intended for a maximum nominal operating voltage of 7.2 V (2V minimum), and each has a stall current of 6.6 A and a no-load current of 420 mA at 7.2 V. Since the motors will briefly draw the full stall current when abruptly starting from rest (and nearly twice the stall current when abruptly going from full speed in one direction to full speed in the other), we recommend a motor driver capable of supplying the 14A combined per-channel stall current of these motors at 7.2 V. We offer several motor controllers that meet these power requirements and make it easy to get this chassis moving:

  • The Simple High-Power Motor Controllers offer a variety of control interfaces: USB, TTL serial, analog voltage (for control from a potentiometer or analog joystick), and RC hobby servo pulses. These controllers are highly configurable and the USB interface makes them very easy to set up and use.
  • The qik 2s12v10 dual serial motor controller provides a simple serial interface and offers features such as acceleration control and current limiting.
  • The TReX dual motor controller offers an RC interface for human control (it can act as a simple ESC right out of the box) and a serial interface for autonomous operation, and it features the ability to blend the two to make a robot that can optionally respond to RC control.
  • The programmable Orangutan X2 robot controller can be the entire control center of an autonomous robot based on this chassis.

Chassis Options

This chassis is available in two different colors (silver and black) and with two different gear ratios (34:1 and 75:1):

  • Silver (chrome-colored hubs), 34:1
  • Silver (chrome-colored hubs), 75:1
  • Black (metallic-red or gold hubs), 34:1
  • Black (metallic-red or gold hubs), 75:1

If you are looking for a bigger robot that is better at scaling inclines and traversing larger obstacles, please consider one of the Wild Thumper 6WD models:

  • Silver (chrome-colored hubs), 34:1
  • Silver (chrome-colored hubs), 75:1
  • Black (chrome-colored hubs), 34:1
  • Black (metallic-red or gold hubs), 75:1

The higher gear ratio version has a lower top speed but can produce greater torque. Note that while the Wild Thumper 4WD chassis includes four wheels, the wheels can be purchased in pairs for use as replacement Wild Thumper parts or as wheels for custom chassis. The wheels are available with metallic-red hubs and chrome-colored hubs. We also offer the Wild Thumper gearmotors individually in a wide range of gear ratios (versions with integrated quadrature encoders are also available, though these will not work with the Wild Thumper chassis).

Modifying the Wild Thumper to use motors with encoders (3MB pdf)
Customer Richard Nguyen has documented his work modifying the Wild Thumper chassis to use 25D motors with encoders in place of the chassis’s included motors.

 

Note: This is not an easy modification, and the chassis can be damaged if it is not done properly, so we generally recommend against it, and we can only provide very limited support for those who want to attempt it. The manufacturer did not intend for the chassis to be modified in this way, and we do not know how well such a modification will work out.
